PHP - Php Domdocument, Finding Specific Tags In A Very Easy Example [here My Approach]
good evening dear Community,
Well first of all: felize Navidad - I wanna wish you a Merry Christmas!! Today i'm trying to debug a little DOMDocument object in PHP. Ideally it'd be nice if I could get DOMDocument to output in a array-like format, to store the data in a database! My example: head over to the url - see the example: the target http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880 I investigated the Sourcecode: I want to filter out the data that that is in the following class <div class="floatbox"> See the sourcecode: <span class="grey"> <span style="font-size:x-small;">></span></span> <a class="navLink" href="http://dms-schule.bildung.hessen.de/suchen/index.html" title="Suchformulare zum hessischen schulischen Bildungssystem">suche</a> </div> </div> <!-- begin of text --> <h3>Siegfried-Pickert Schule</h3> <div class="floatbox"> See my approach: Here is the solution return the labels and values in a formatted array ready for input to mysql! <?php $dom = new DOMDocument(); @$dom->loadHTMLFile('http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880'); $divElement = $dom->getElementById('floatbox'); $innerHTML= ''; $children = $divElement->childNodes; foreach ($children as $child) { $innerHTML = $child->ownerDocument->saveXML( $child ); $doc = new DOMDocument(); $doc->loadHTML($innerHTML); //$divElementNew = $dom->getElementsByTagName('td'); $divElementNew = $dom->getElementsByTagname('td'); /*** the array to return ***/ $out = array(); foreach ($divElementNew as $item) { /*** add node value to the out array ***/ $out[] = $item->nodeValue; } echo '<pre>'; print_r($out); echo '</pre>'; } well Duhh: this outputs lot of garbage. The code spits out a lot of html anyway. What can i do to get a more cleaned up code!? What is wrong with the idea of using this attribute: $dom->getElementById('floatbox'); any idea!? any and all help will greatly appreciated. season-greetings db1 Similar TutorialsDelete ... need to change host .. I use the Wholesale Suite Premium Prices plugin with WooCommerce. I have 6 specific wholesale roles out of 15 that I wish to hide two specific shipping methods from being selected for the 6 exceptions. I'm just trying this on my staging server at this time using a code snippet example that I found and modified for my specific conditions. Would the following work for this purpose?
/* Hide specific shipping methods for specific wholesale roles */
add_filter( 'woocommerce_package_rates', function( $shipping_rates ) {
// User role and shipping method ID to hide for the user role
$role_shipping_method_arr = array(
'ws_silvia_silver' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
);
// Getting the current user role
$curr_user = wp_get_current_user();
$curr_user_data = get_userdata($current_user->ID);
// Wholesale Suite Roles
if (isset($current_user) && class_exists('WWP_Wholesale_Roles')) {
$wwp_wholesale_roles = WWP_Wholesale_Roles::getInstance();
$wwp_wholesale_role = $wwp_wholesale_roles->getUserWholesaleRole();
// Loop through the user role and shipping method pair
foreach( $role_shipping_method_arr as $role => $shipping_methods_to_hide ) {
// Check if defined role exist in current user role or not
if( in_array( $role, $current_user->roles) ) {
// Loop through all the shipping rates
foreach( $shipping_rates as $shipping_method_key => $shipping_method ) {
$shipping_id = $shipping_method->get_id();
// Unset the shipping method if found
if( in_array( $shipping_id, $shipping_methods_to_hide) ) {
unset($shipping_rates[$shipping_method_key]);
}
}
}
}
}
return $shipping_rates;
});
Any insights as to how to accomplish this would be greatly appreciated. Lyse I have some code $doc = new DOMDocument(); $doc->loadHTML( '<html> <head><title>Test</title></head> <body></body></html>' ); $doc->encoding = 'iso-8859-1'; file_put_contents('test.html', $doc->saveHTML()); when i view the output file i get <html><head><title>Test</title></head><body></body></html> all on one line is there no way of having it format it like the original source code so that its not all bunched together? Is there any reason that people can think as to why DOMDocument::saveHTML would remove the following: Code: [Select] <![if !vml]> <img src="someimage.jpg" /> <![endif]> A little clarification... This HTML comment tag is used in my company's email newsletter code and is necessary to make Outlook 2007 behave properly. For whatever reason, saveHTML strips it out. I know that this doesn't conform to HTML standards and I'm guessing that that is why it is being stripped. BUT, from reading on the internet, saveHTML can produce junk html code anyways. Any help is appreciated. Hi all, I am pretty new to php and I am having an issue trying to load an XML document. When ever I try to use Xpath it negates all the code below the line, including the HTML, and returns a white page. here is my code: Code: [Select] <html> <head> <?php $xpath = new DOMXPath("structure.xml"); ?> <body> hello world </body> </html> I checked phpinfo() and I have both the DOM and XPath enables and installed. I have also tried using just DOM and that worked so it is only Xpath that is not working. Ideas? Thank you James S Hi guys, Just starting to play with PHP Domdocument, only to fail at the very first step:
<?php
$html = 'test/php/somefile.html' ;
if(!empty($html)){
$dom_1 = new domDocument ;
$dom_1->loadHTML($html) ;
$links = $dom_1->getElementsByTagName('li') ;
foreach ( $links as $link) {
// echo $link ;
echo $link->nodeValue, PHP_EOL;
}
}
?>
When I visit it in a browser I get a WSOD, what am I missing? I am wanting to make a product list page with PHP. At the moment I using this code: Code: [Select] $query = "select * from products where category = 'Belts'"; $result = mysql_query($query); while($row=mysql_fetch_assoc($result)) { echo $row['name']; } The result is something like this: http://i51.tinypic.com/2w56ljq.png What I want is for them to be aligned like this: http://i53.tinypic.com/w811tz.png Eventually, I am also going to include an image with each product. How would I go about alignment? With CSS or PHP? I just finished (or so I thought) a project. But my client's server runs PHP4, so I need to adapt my code. Here's what stopped working: Code: [Select] $localClasses = new DOMDocument; $localClasses -> load("file.xml"); $localClasses -> get_elements_by_tagname('Title') -> item(0) -> firstChild -> nodeValue Here's my petty attempt at trying to adapt this code to run in PHP4: Code: [Select] $file = file_get_contents("localClasses.xml"); $localClasses = new DOMDocument($file); $test = $localClasses -> get_elements_by_tagname('Title'); $testText = $test -> item[0] -> firstChild -> nodeValue; print $testText; This doesn't give me any errors, but nothing shows up. Any help would be appreciated. Thanks for reading! so there's some html i'm having to fetch and parse for personal use...but some of the data i want is started in a table written this way: rawTableData = {"rows": [{"colname1": value, "colname2": "value", "colname3: value} how can i use domdocument to parse this data if say i want the value for colname2? there are no tags for me to use. Hi guys, Reading this from php.net, has got me a wee bit confused. Trying to implement is has got me doubly confused! My code:
$dom = new DOMDocument;
libxml_use_internal_errors(true);
$dom->loadHTMLFile($parent_node);
if($dom->childNodes <>0) {
$kids = array (
'url' => $parent_node,
'No_of_kids' => count($dom->childNodes)
);
}
Results in '' Notice: Object of class DOMNodeList could not be converted to int' How the heck am i supposed to count the childNodes? Hi, I have a php code that could extract the categories and display them. However, I still can't extract the numbers that goes along with it too(without the bracket).
This is my code:
<?php
$grep = new DoMDocument();
@$grep->loadHTMLFile("http://www.lelong.com.my/Auc/List/BrowseAll.asp");
$finder = new DomXPath($grep);
$class = "CatLevel1";
$nodes = $finder->query("//*[contains(@class, '$class')]");
foreach ($nodes as $node) {
$span = $node->childNodes;
echo $span->item(0)->nodeValue."<br>";
}
?>
This is my desired output:
Arts, Antiques & Collectibles : 9768 B2B & Industrial Products : 2342 Baby : 3453 etc...Any help is appreciated. Thanks! good evening dear PHPFreaks - hello to everybody. i want to create a link parser. i have choosen to do it with Curl. I have some lines together now. Love to hear your review... Since i am new to programming i love to get some hints from experienced devs. Here some details: well since we have several hundred of resultpages derived from this one: http://www.educa.ch/dyn/79362.asp?action=search Note: i want to itterate over the resultpages - with a loop. http://www.educa.ch/dyn/79376.asp?id=1568 http://www.educa.ch/dyn/79376.asp?id=2149 i take this loop: for($i=1;$i<=$match[1];$i++) { $url = "http://www.example.com/page?page={$i}"; // access new sub-page, extract necessary data } Dear PHP-Freaks, what do you think? What about the Loop over the target-Urls? BTW: you see - there will be some pages empty. Note - the empty pages should be thrown away. I do not want to store "empty" stuff. well this is what i want to. And now i need to have a good parser-script. Note: this is a tree-part-job: 1. fetching the sub-pages 2. parsing them 3. storing the data in a mysql-db Well - the problem - some of the above mentioned pages are empty. so i need to find a solution to leave them aside - unless i do not want to populate my mysql-db with too much infos.. Btw- parsing should be a part that can be done with DomDocument - What do you think? I need to combine the first part with tthe second - can you give me some starting points and hints to get this. The fetching-job should be done with CuRL - and to process the data into a DomDocument-Parser-Job. note ive taken the script from this place: http://www.merchantos.com/makebeta/php/scraping-links-with-php/ function storeLink($url,$gathered_from) { $query = "INSERT INTO links (url, gathered_from) VALUES ('$url', '$gathered_from')"; mysql_query($query) or die('Error, insert query failed'); } for($i=1;$i<= 10000; $i++) { $target_url = "http://www.educa.ch/dyn/79376.asp?id={$i}"; } // access new sub-page, extract necessary data $userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)'; // make the cURL request to $target_url $ch = curl_init(); curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); curl_setopt($ch, CURLOPT_URL,$target_url); curl_setopt($ch, CURLOPT_FAILONERROR, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER,true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $html= curl_exec($ch); if (!$html) { echo "<br />cURL error number:" .curl_errno($ch); echo "<br />cURL error:" . curl_error($ch); exit; } // parse the html into a DOMDocument $dom = new DOMDocument(); @$dom->loadHTML($html); // grab all the on the page $xpath = new DOMXPath($dom); $hrefs = $xpath->evaluate("/html/body//a"); for ($i = 0; $i < $hrefs->length; $i++) { $href = $hrefs->item($i); $url = $href->getAttribute('href'); storeLink($url,$target_url); echo "<br />Link stored: $url"; } Dear PHP-Freaks, what do you think? What about the Loop over the target-Urls? love to hear from you ! It is easy to get image or link by DomDocument, but I did not find a way to get image with its target link. Imagine a html as Code: [Select] <div class=image> <a href='http://site.com'><img src='imagelink.jpg'></a> </div>How to get both the image link and href? $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath($dom); $hrefs = $xpath->evaluate("/html/body//div[@class='image']"); for ($i = 0; $i < $hrefs->length; $i++) { $href = $hrefs->item($i); Now to get the image and its href, we need first getElementsByTagName('a') and getElementsByTagName('img') but they do not work inside foreach. What's your idea? Code: [Select] $domdoc=new DOMDocument(); $domdoc->formatOutput=TRUE; $empty_cart_xml= '<Order> <Cart> <Items> <Item>1</Item> <Item>2</Item> <Item>3</Item> </Items> </Cart> </Order>'; $domdoc->loadXML($empty_cart_xml); print $domdoc->saveXML()."<hr/>"; //works up to this point $xpath=new DOMXPath($domdoc); $items=$xpath->query('Order/Cart/Items'); foreach($itemses AS $items) { $items->appendChild($domdoc->createElement('Item','4')); } print $domdoc->saveXML(); All I want to do is to add a new Item to Items. What am I doing wrong? Imagine an html with the following structure Code: [Select] <div class="item"> <div class="title"> <a class="title" href="http://www.domain.com/title.html">Title is here</a> </div> <div class="image"> <a href="http://www.domain.com/title.html"><img src=image.jpg /></a> </div> </div> How to make an array containing $title - $url - $image_url ? Hi everyone,
So I'm relatively new to OO PHP and moreover, OO PHP with MVC design pattern.
This may be a largeish post so please bear with me on this one!
So here is a scenario that I'd like to understand. There are likely multiple ways to go about this, but it'd be nice to see what is said.
I'll include what I think should be the solution here and hopefully i'll get some feedback about it.
Scenario:
A page needs to display a list of "parts" for a car. A database table already exists with these parts. The list of parts on the page need to be ordered by name on first load, but then can be re-ordered by users using a drop down list. They can also be filtered, and searched.
A page also exists to display a single car part.
What I think should be, and what i'm struggling with:
Model:
I will have a "part" object which represents an individual car part.
The part object will use a database abstraction layer. On "new Part()" will generate an empty object. ->Load( id ) will load an individual part.
Controller:
I do not know how I would implement this. I know it would contain methods to Filter(), Search() and Order() and that would directly access the Model.
View:
I am lost here too, I need to display a list of car parts, and on another page, a single car part. I understand I should use the same Model for both. However I do not see how I would list the parts.
Some Questions:
Should I have another "model" that is a list of the "Part" model called PaetListModel, or should "Part" be able to generate that list?
I clearly should have 2 views, one for singular part, one for list of parts. Should the view access the model to generate the list before using the data for output?
Should the controller be used in the view instead of the model to generate the initial list (or singular) on page load?
Should the filter functions in the controller reload the "PartsList" from wherever our list is stored?
I think the most important question for me though is:
How would YOU implement the above green scenario?
I would like to learn from peoples examples so I get an idea of what road to follow
Hello everyone, I am new to php and I need a confirmation if this is the correct approach for a code I wrote. Basically, I have a contacts.php page where I have a bootstrap table and a modal with some fields to add a new contact. I managed to write all the code, it works perfect but I want to know if this approach is ok. The application will be much more complex and I don;t want to start on the wrong foot here. I have 2 files: contacts.php and add_new_contact.php. First file, contacts.php:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<!-- ............ -->
</head>
<body>
<!-- ............ here is the page layout-->
<!-- Then I have my modal from bootstrap -->
<div class="modal fade" id="addContact" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<form action = "add_new_contact.php" method="post">
<!-- .....content with all the inputs -->
<button type="submit" class="btn btn-primary">Save to database</button>
</form>
</div>
</body>
</html>
Now, in form action I am telling html to go to add_new_contact.php where I wrote the code for inserting all the values to the database. When doing this, it opens the page and it stays blank because there is no html there. So, in that php file I added a redirect code to the initial contacts.php. Here is the code: Second file: add_new_contact.php:
<?php
//all the code needed to insert the contact in the database
header("Location: http//..../contacts.php");
exit();
?>
So, this works fine. But is this the best way to do it? Thank you. I'm looking for some direction as I approach a new challenge. I have a table named friends_and_family and it contains name, email, and age fields. I'm planning a party and want to invite 10 of the people that are between 20 and 35 years old. The format I am considering would query the table and provide a list of those members that fit the age requirement. I would like to generate that result (which I should be capable of handling) so that each person listed has a checkbox next to their name. I imagine I will be creating a resultant form, so that I can then evaluate the result and select the checkboxes for those specific people that I want to invite. Upon submission, an email will be sent to the people with selected checkboxes. How should I approach this best? A for each loop? Implode an array? I'm not very good with AJAX, so I'm thinking along these lines.
