PHP - Parsing Xml And Removing Parent If Link = String
Hello,
Any help would be great. I'm filtering and rss feed and to create a new feed with some <item>'s removed. Here is a snippet from the source file. <item> <title><h1>Indians, Pacers and Colts attendance is only part of story</h1></title> <link>http://www.newsweek.com/the-score/2010/07/29/indians-pacers-and-colts-draw-similar-sized-crowds/PARAMS/post/21385</link> <description></description> </item> <item> <title><h1>Declining attendance forcing Speedway to make changes</h1></title> <link>http://www.newsweek.com/declining-attendance-forcing-speedway-to-make-changes/PARAMS/article/21369</link> <description></description> </item> <item> <title><h1>Three issues that could derail Indy's 2012 Super Bowl</h1></title> <link>http://www.newsweek.com/the-score/2010/07/27/three-issues-that-could-derail-indys-2012-super-bowl/PARAMS/post/21341</link> <description></description> </item> I'm wanting to use the link tag to detect the item that need to be removed for the new rss feed. All <item>with <link> that contain http://www.newsweek.com/the-score/ as the beginning of the link need to be filtered out. Here is my code so far. <?php echo '<?xml version="1.0" encoding="UTF-8"?> <rss version="2.0" xmlns:media = "http://search.yahoo.com/mrss"> <channel> <title>CLE Calendar</title> <description>CLE Calendar</description> <language>en-us</language> <pubDate>June 14, 2010</pubDate> <lastBuildDate>June 14, 2010</lastBuildDate> <ttl>15</ttl>'; ?> <?php $rss = new SimpleXMLElement('http://www.newsweek.com/mobile-app/rss/feed?rssId=18&premium=false', null, true); ?> <?php foreach ($rss->channel->item as $items): ?> <item> <title><?php echo '<h1>' . $items->title . '</h1>'; ?></title> <link><?php echo $items->link; ?></link> </item> <?php endforeach; ?> </channel> </rss> Thanks in advance, MK Similar TutorialsI have the following function, which takes a string with commas in it and attempts remove those commas. The way I have it here is that I use explode to take out the commas, which makes an array, and then iterate through that array to put a string back together without the commas. function tags_to_sort_by( $sortMeta ) { $sortByArray = explode(",", $sortMeta); $sortByCount = count($sortByArray); for ($i = 0; $i < $sortByCount; $i++) { $sortByString += $sortByArray[$i]; } return $sortByString; } What does not work is the following line: $sortByString += $sortByArray[$i]; Somehow that outputs a 0, which I don't understand. It should output something like: arrayItem1 arrayItem2 array3 etc. My question is if there either is an easier way to remove the commas from the original string or what I am doing wrong in this line: $sortByString += $sortByArray[$i]; // I am trying to concatenate each part of the array back into the string. Thanks a lot for help with this! I got the below Div. I gather i got the following subtitles in the div (sometimes not all) $subtitle = array('Postal Address:','Street:','Town :','Telephone:','Mobile:','Contact Person:','Country:','e-mail:','Website:'); It occurs that the title is enclosed in font tag and the title text is what follows after the closing </font> upto the next <br>; Please help on retrieving The Title and the text. Regards <div align="left" id="tabledetails__"><font color="#4E779F" size="+1">Beverages Ltd</font><br> <font color="brown">Postal Address: </font>1604120 <br> <font color="brown">Street: </font>Karatina Town Council <br> <font color="brown">Town :</font>Kampala <br> <font color="brown">Telephone: </font>+254 414 983456 <br> <font color="brown"> Country: </font>Kenya <br> <font color="brown">e-mail: </font><a href="mailto:sales@karatina.co.ug">sales@karatina.co.ug</a> </div> I remember doing this over a year ago, but now I've completely forgotten how to do this, and I'd much appreciate some pointers: I have a string as follows: 12|445|3|321|88|2 I'd like to do 2 things: First, I'd like to count the number of numbers (6 in this case: 12, 445, 3, 321, 88, 2); Then I'd like to enter them into an array. How do I go about this? Please help ... What I want to do is simple: The string "this_is_an_example.php" should return "this_is_an_" while: "this_is_an_example_filename.php should return "this_is_an_example_" Is there a simple function which can cut off the part after the last _ ? I have been looking and trying several functions, but can't seem to find the right one for this. (the last _ being cut off of course wouldn't be a problem I couldn't live with :-) ) Any help will be greatly appreciated! Here's what I need to do: I have a page that reads file and simply echos it. $mystring = file_get_contents($file); echo "$mystring"; There is one piece of info I need to parse out and then use as part of my page title. The phrase I need to parse is an HTML comment field and looks like this: <!--PageTitle=<some text here> --> I'm sure this is simple but I'm clueless as you can tell. How can I do this? DryAquaman hi im having trouble removing ' from strings
so say
$name = "D'vion";
$newname = str_replace("'","",$name);
but this just returns the same.
thanks matt
Hello Everyone, I am working on a project I pull the field names from the database. I am trying to remove the underscore (_) when the field name is displayed. Does anyone know how I would do that? Here is the code that I am working with Code: [Select] $i = 0; while ($i < mysql_num_fields($fieldnamesquery_result)) { $meta = mysql_fetch_field($fieldnamesquery_result, $i); if (!$meta) { echo "No information available"; } $meta = str_replace("_", " ", $meta); $tablecolumn .= "<p>" . $meta->name . ":<input type='text' name='" . $meta->name . "' id='" . $meta->name . "' /></p>"; $i++; Hello guys, I want to remove part of a string and convert it to a var instead of echoing it out.. How would I do it.. $string = "temp_photo/testing.jpg"; I want to remove temp_photo so the out put should be $filename2 = testing.jpg Please advise.. Thanks, Dan Hey all, I'm using the form 'method="get" action="results.php"' on my search form... Say someone uses my 'Photo search' to search my database for aircraft, and leaves all fields blank. In this case, the only field of the search is 'aircraft'. This will take the user to 'results.php?aircraft='. Is there anyway to remove the sting if there is no search value? So it would just read 'results.php'? This is the code i have so far: Code: [Select] <?php if(isset($_GET['aircraft'])){ $aircraft = $_GET['aircraft']; } if($aircraft==""){ $aircraft = mysql_query("IGNORE aircraft"); } ?> Thanks in advanced! In <div id="chart_rt">%3$s</div> below, it is populated with a string that always begins with a number followed by a colon (from 1: to 25:). I see that ltrim removes characters from the beginning of a string but I don't see how to compensate for the extra character in 10: through 25: function wp_rss( $url, $num_items = -1 ) { if ( $rss = fetch_rss( $url ) ) { echo '<div id="charts">'; if ( $num_items !== -1 ) { $rss->items = array_slice( $rss->items, 0, $num_items ); } //start count $i = 1; foreach ( (array) $rss->items as $item ) { printf( '<div id="chart_lt">'.$i.'</div><div id="chart_rt">%3$s</div>', esc_url( $item['link'] ), esc_attr( strip_tags( $item['description'] ) ), htmlentities( $item['title'] ) ); //increment $i++; } echo '</div>'; } else { _e( 'An error has occurred, which probably means the feed is down. Try again later.' ); } } Hey guys! I found a flush function and it seems to be working well, but sometimes it will cut off characters. It's very strange. Here's my flush function: function out($str) { echo $str."<br />\n"; vbflush(); } function vbflush() { if (ob_get_length()){ @ob_flush(); @flush(); @ob_end_flush(); } @ob_start(); }And I'm calling it like this:out('Waiting 30 seconds until execution');And this is my output: Code: [Select] Waiting 30 seconds until executioAnyone know why? %3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only). 1: 2: 3: etc... Is there a way to remove the number and the colon entirely and leave the rest of the string intact? Code: [Select] function wp_rss( $url, $num_items = -1 ) { if ( $rss = fetch_rss( $url ) ) { if ( $num_items !== -1 ) { $rss->items = array_slice( $rss->items, 0, $num_items ); } //start count $i = 1; foreach ( (array) $rss->items as $item ) { printf( '<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>', esc_url( $item['link'] ), esc_attr( strip_tags( $item['description'] ) ), htmlentities( $item['title'] ) ); //increment $i++; } Ashley This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=321479.0 Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.
Here is what the the output of the RSS looks like.
<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font> 20:00 PM - 6:00 AM</div>]]></description>Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. Incident: Exit ramp closed. Current Status: Open Affected Lanes: Exit Ramp Dates: Wednesday, May 28 - Thursday, May 29 Days Closed: SMTWTFS 20:00 PM - 6:00 AMThis is how it is formated in the td cell.
<td style='{$td2Style}'><strong>Incident:</strong> {$incident_data_desc}</td>\n";
So as you can see above, there is nothing before it that would cause it to break to a new line both in the table or in the RSS.
So how can I remove that first return only is that is on the same line with it and not below it.
I have tried this and a couple of other things like trim with no luck.
$description = $item->description;
$incident_data_desc = str_replace("\r", '', $description );
Note, I only need that first one removed, the others are fine. I can do it but it will remove all the breaks and I only want to remove that first one that is causing the line to be on a new line.
Any suggestions?
-ThanksI have a string of mixed Japanese or Chinese and Western characters and I would really like to leave the western characters and remove the others. Is there any way to detect which UTF-8 characters are Japanese/Chinese and to remove them? I have tried to use this which I found on another thread but my version of PHP (5.3) will not allow the /u in the following Code: [Select] echo "<BR>".preg_replace('/[^\u4E00-\u9FFF]+/', '', $string); I have tried using various combinations of /p (these, plus others) Code: [Select] echo "<BR>".preg_replace('/\p{Bopomofo}+/u', '', $string); echo "<BR>".preg_replace('/\p{Hiragana}+/u', '', $string); and the /x{} option tells me the numbers are to large Code: [Select] echo "<BR>".preg_replace('/[^\x{4E00}-\x{9FFF}]+/', '', $string); My string for this example is this but any combination of western and Japanese/Chinese characters are possible in the title. 2011.12.06 19:00-20:00 / ふくいちライブカメラ (Live Fukushima Nuclear Plant Cam) | Uploaded: 06 Dec 2011 Thanks for any help.

Hello everyone, This is the code I need to implement: https://developer.wordpress.org/reference/functions/wp_get_attachment_link/
and this is the file where it has to included: I have been becoming more and more familiar with PHP over the past few months, but this problem stumps me. How can I take a string of words separated by spaces taken from an XML feed (example: word1 word2 word3 word4) and turn it into something like this: <a href="word1">word1</a> <a href="word2">word2</a> ... and so on. This has to be done on the fly, since it is taking the words from the XML feed, they change depending on the page. I want them to be in a vertical column, and be able to link each one to the search page for that word, so each link has to be different. An even more in-depth problem, how can I sort it then so that there are multiple columns if necessary, say one page only has 3 words, but another has 50. How can I split them up into multiple vertical columns, say with 10 words in each? Have I confused anyone yet? I am trying to wrap a string with an anchor tag if it finds a match with a block of text. Here is an example text block: CONOCO 1'10x8 VC DF TP SGN||PRINCIPAL ILLUMINATION||ENG: CO3028TP_0VPR||DWG: CO200428||TO BE: DYED DIESEL (SPEC)|| The string I would want to wrap with a link would be "CO200428". The next problem is the drawings (what I'm searching the text for) has over 115,000 possibilities. The text blocks to search are over 1300. I have the drawing names stored in a simple mysql table...but doing a foreach takes forever...I imagine it will take even longer when looking in the text blocks... Is there a way to easily to do the anchor wrap? I don't know regex very well... |
