Question

I am looking for a way to delete part of a string from an xml file. At the moment i have some content like so:

<description>blah blah blah blah</description>

I would like to use a function to find

<description> & </description>

and delete the content between. It would also need to repeat this throughout the xml document to remove any content between further description tags.

Im not sure how to start at attempting this and any sample code would be much appreciated.

If your document is fully XML, you can use the DOMDocument extension to manipulate it.
See especially http://www.php.net/manual/en/domdocument.getelementsbytagname.php
You could write something like:

$dom = new DOMDocument;
$dom->loadXML(' YOUR XML CODE HERE ');
$descriptions = $dom->getElementsByTagName('description');
foreach ($descriptions as $description) {
   $description->nodeValue = '';
}
$xml = $dom->saveXML();
