How do I rename XML values using php? -

how rename value in xml using php? i've got far:

<?php $q = $_get["q"]; $q = stripslashes($q);  $q = explode('|^', $q);  $old = $q[0];  $dom                     = new domdocument; $dom->preservewhitespace = false; $dom->formatoutput       = true;  $dom->load("test.xml");  $xpath   = new domxpath($dom);     $query1  = 'channel/item[title="' . $old . '"]/title'; $entries = $xpath->query($query1);  foreach ($entries $entry)  {             $oldchapter = $entry->parentnode->removechild($entry);      $item       = $dom->getelementsbytagname('item');      foreach ($item $items)      {         $title = $dom->createelement('title', $q[1]);                     $items->appendchild($title);                 } }      $dom->save("test.xml"); 

basically, take 2 titles url, old existing title, , 1 user wants change (so oldtitle|^newtitle), , puts them array.

what i've tried doing removing existing old title, , making new title with, using new title value url, doesn't seem working. going wrong, or there easier way of doing this?

the way domnode::replacechild(). majority of code correct, you've over-complicated of dom stuff.

try this:

<?php      $q = $_get["q"];     $q = stripslashes($q);      $q = explode('|^', $q);      $old = $q[0];      $dom                     = new domdocument;      // *before* loading document     $dom->preservewhitespace = false;     $dom->formatoutput       = true;      $dom->load("test.xml");     $xpath = new domxpath($dom);      $query1  = 'channel/item[title="' . $old . '"]/title';     $entries = $xpath->query($query1);      // need in loop     foreach ($entries $oldtitle) {         $newtitle = $dom->createelement('title', $q[1]);         $entry->parentnode->replacechild($newtitle, $oldtitle);     }      $dom->save("test.xml");
