    read DOMDocument ( php.net/manual/en/class.domdocument.php ) or SimpleXML ( php.net/manual/en/book.simplexml.php ) manual. Commented Feb 26, 2012 at 15:26
  • If this is all the xml within the file would it not be easier to have a template with a placeholder then you can use simple str_replace to insert the values then replace the file, else you would need to xpath the node and then rebuild the xml Commented Feb 26, 2012 at 15:33

Use SimpleXML

  • load the file with $xml = simplexml_load_file('filename')
  • manipulate the value in $xml
  • save the output of $xml->asXML();
