PHP - Portiing Over A Parser From Bs4 To Simplehtmldom-parser

Hi All.

I was working on this class for the last .. 2 hours or so. I was just wondering, if any of you could see anything immediatly wrong with it. I haven't really had chance to test it. If it does work. Help yourselves to it.

Im using some software called php html dom parser i wont to be able to keep the souce tidy

i.e before dom parser

is there anyway i can keep it like the original fil after dom?

Code: [Select]
<?php
$dom = new DOMDocument();
$dom->loadHTMLFile('http://en.wikipedia.org/wiki/Liverpool_F.C.');
$domxpath = new DOMXPath($dom);
foreach ($domxpath->query('//span[@id="Players"]/../following-sibling::table[1]//span[@class="fn"]') as $a)
{echo
"
<p>$a->textContent</p>
";
};
?>

Hello, how can I parse an XML that includes all of the $a->textContent with a tag like <player></player>?

Everything works fine, unless I add this stupid thing to get rid of people using HTML
Code: [Select]
$text = pun_htmlspecialchars($text);
Once I add that to my function, no bbcodes work at all?  But I cant use html.. (which is good) but I need to beable to use BBCODE, and parse hackers from using html also, any help?



MY CODE absolutely destroyed the forum page

here it is:

http://pastebin.com/jv7m47kn

Ok, so i'm working on my forum software in PHP to both get some knowledge out of this and accomplish something in the run. While adding a BBCode parser, I ran into some trouble.

This is what happened:
http://ebulletin.ballindesign.com/message.php?id=1

As you can see, a <br /> tag shows up after EVERY line...
Here is my BBCode parser:

Hi guys!

Am trying to get hold of a PHP Math Expression Parser that follows correct precedence and executes custom functions. Can somebody share his scripts? or lead me to the right directions?

Hope you can help! Thanks a lot! My boss is gonna kill me soon. This is 1 week overdue already.

Jon

In the following code, I am getting an error: Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting T_STRING or T_VARIABLE or '{' or '$' in XXX on line 235

Line 235 is the second line in the code snippet
Code: [Select]
       $result = mysql_query( $querystr, $this->linkid );
        $this->"queryid".$id = $result;
        if ( defined( "SWIFTDEBUG" ) )
        {
Thanks

Dear all,

Hello, i'm a newbie programmer. I want to implement the concept about recursive descent parser for natural language (english). The concept was found in http://nltk.sourceforge.net/doc/en/ch07.html#rdparser. But my problem is, how to implementation the concept/theory to PHP code ? Anyone would to help me to give the advice or tutorial or maybe anyone has to make script before?

Thank you very much in advance.

I have an XML file (differences.xml)
<element>
<item code="lM" name="castle" type="building">
<cost>5000</cost>
</item>
...more items....
</element>

I have parser.php whih parses the XML and displays all item names in a checklist for the user to select items. These selected items are method=post back to parser.php which re-parses the XML where selected item = item name and SHOULD then display all selected items' names (and more):
<?php        
if (isset($_GET['formSubmit'])) {
$option = $_POST['option'];
$option = array_values($option);
if (!empty($option)){
$xml = simplexml_load_file('differences.xml');
$i = 0;
$count = count($option);
while($i < $count)
{
$selected = $xml->xpath("//item[@name='".$option[$i]."']");
echo $selected[$i]['name'];
$i++;
}
}else{
echo "No items selected, Please select:";
}
}else{

$xml = simplexml_load_file('differences.xml');
$object = $xml->xpath('//item');
$count = count($object);
$i = 0;
echo "<form method='POST' action='parser.php'>";
while($i < $count){
$xmlname = $object[$i]['name'];
echo "<input type='checkbox' name='option[".$i."]' value='$xmlname'>".$xmlname;
echo "<br>";
$i++;
}
echo "<br><input type='submit' name='formSubmit' value='Proceed'><br>";
echo "</form>";
}
?>

The problem is, the parser is only displaying the first selected item and isn't outputting the rest. To clarify the code:
- The first half executes only if items have been previously selected in the form. If no items were selected, it goes to the secod half, which parses the XML file and presents the checklist form for the user to select items. THIS WORKS GREAT.
- After pressing the submit button, the items are sent using POST and the page is reloaded. THIS WORKS GREAT.
- After reloading, the first half executes and finds the $_POST and resets the array so that it works with the coming loop. THIS WORKS GREAT.
- The loop parses the XML and returns only those item names that have been selected in the $_POST. THIS DOES NOT WORK.

So my question is: what's wrong with my code? The array $options has all the proper information, but the parser is only outputting the first item. All consecutive loops result in empty space with no output.

I've been at this for 2 weeks and can't find the solution. Any help is appreciated!

Hello
I would like to know how to parser chemical and mathematical formulas into images or html-based layout. Please advise me.
Thank you.

good day 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
}


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.
No Problem he But how  to do the DOM-Document-Job ...

i have installed FireBug into  the FireFox...

now i have the Xpaths for the sites:

Hello all,

I have here some PHP code that was working fine under my installation of XAMPP (it has PHP 5). When I moved the following code to my web hosting site, 1&1, it threw up the error you see in the subject field. I attempted to create a new htaccess file in the same directory as my website files to force PHP 5, but I still get the same error. Any ideas on how else I can parse the XML? My code is as follows:

//get ALL instances of wanted element(s)
            $titles = $item->getElementsByTagName('title');
            $dates = $item->getElementsByTagName('pubDate');
            $descriptions = $item ->getElementsByTagName('description');
            
            //formatting
            $content = ('
               <ul class ="blog_entry">
                  <li class="title_entry">
                  '.$titles->item(0)->nodeValue.
                  '</li>
                  <li class="date_entry">
                  Posted on '.date("M d, Y H:i",strtotime($dates->item(0)->nodeValue)).
                  '</li>
                  <br>
                  <li class="description_entry">
                  '.$descriptions->item(0)->nodeValue.
                  '</li>
               </ul>
               ');
            echo $content;
            }

Personally, I think it's a problem with the nodeValue, since apparently the PHP 5 push doesn't seem to work. Any other way I could reference the XML values I get?
