I'm sorry, but I'm a bit confused, I don't understand what the code is supposed to do

I'm trying to pick out items from an XML file by their titles using Xpath in DOM, but because some have apostrophes, and others have quotes, it doesn't work. I've tried replacing the apostrophes using this $query1 = 'channel/item[title='.$p.']/title'; but it only works for the apostrophes, not the quotes. Any advice on how to do this? <?php $q = $_GET["q"]; $q = explode('|^', $q); $counts = count($q); unset($q[$counts-1]); $p = stripslashes($q); $q = stripslashes($p); $dom = new DOMDocument; $dom->preserveWhiteSpace = false; $dom->formatOutput = true; $dom->Load("../$userid.xml"); $xpath = new DOMXPath($dom); foreach ($q as $r) { $p = preg_replace("/'/","",$r); $query1 = "channel/item[title="'.$p.']/title"; $query2 = "channel/item[title="'.$p.']/url"; $query3 = "channel/item[title="'.$p.']"; $entries = $xpath->query($query1); $entries2 = $xpath->query($query2); $entries3 = $xpath->query($query3); foreach ($entries as $entry) { foreach ($entries2 as $entry2) { foreach ($entries3 as $entry3) { $oldchapter = $entry->parentNode->removeChild($entry); $oldchapter2 = $entry2->parentNode->removeChild($entry2); $oldchapter3 = $entry3->parentNode->removeChild($entry3); $dom->preserveWhiteSpace = false; } } } } $dom->formatOutput = true; $dom->save("../$userid.xml") ?> Basically, my code extracts titles from a URL, separated by "|^" (For example title1|^title2|^title3|^). Because the "|^" is appended to the end of each title, I have to remove the empty value from the array. Then, because the titles with apostrophes come in like "Title\\'s", I have to strip slashes twice to get rid of them. Then I load a new DOMdocument, and find the titles from the URL in my existing XML document. Then I want the code to remove the whole items (titles, urls and the item itself) which have the same titles as the ones in the URL, and then save the document.

I can't use a database, because the video player I'm using only supports xml and rss playlists. I don't understand what you mean by export to XML (sorry). Also, what are the proper functions I should be using. (sorry, complete noob)

Basically, I am writing a script in PHP, which can take YouTube videos from playlists, items from RSS feeds and podcasts, and individual YouTube videos and files, and places them into an XML document, so they can browsed and kept in one place. I also have a script which removes these items, if the user wants. The problem I'm facing is with characters. Because I can't control what the user will name their videos/files, or how they're named in the feed, the titles could have quotes, brackets, ampersands, hashes etc, which causes problems when they're being removed and Because I'm using Xpath (which can be temperamental at the best of times) in the remove script, any items with titles with these characters won't get removed. Here's my remove code: <?php $q = $_GET["q"]; $q = stripslashes($q); $q = explode('|^', $q); $counts = count($q); unset($q[$counts-1]); $dom = new DOMDocument; $dom->preserveWhiteSpace = false; $dom->formatOutput = true; $dom->Load("../$userid.xml"); $xpath = new DOMXPath($dom); foreach ($q as $r) { $r = preg_replace("|&|", '&', $r); $r = preg_replace('|"|', '"', $r); $query1 = 'channel/item[title='.$r.']/title'; $query2 = 'channel/item[title='.$r.']/media:content'; $query3 = 'channel/item[title='.$r.']'; $entries = $xpath->query($query1); $entries2 = $xpath->query($query2); $entries3 = $xpath->query($query3); foreach ($entries as $entry) { foreach ($entries2 as $entry2) { foreach ($entries3 as $entry3) { $oldchapter = $entry->parentNode->removeChild($entry); $oldchapter2 = $entry2->parentNode->removeChild($entry2); $oldchapter3 = $entry3->parentNode->removeChild($entry3); $dom->preserveWhiteSpace = false; } } } } $dom->preserveWhiteSpace = false; $dom->formatOutput = true; $dom->save("../$userid.xml") ?> How it works is when the user selects the items they want to remove, using a select box, the selections are put into the URL. My code extracts the titles from the URL, separated by "|^" (For example title1|^title2|^title3|^). Because the "|^" is appended to the end of each title, I have to remove the empty value from the array. Then I load a new DOMdocument, and find the titles from the URL in my existing XML document. Then I want the code to remove the whole items (titles, urls and the item itself) which have the same titles as the ones in the URL, and then save the document, but because some of the titles could have &, ", * or #, they don't get removed. Is there a way that I can maybe screen, and change the characters to get it to work (I tried this with "preg_replace", but it didn't work), or even change them before they're saved to the XML in the first place? Any advice?
