[Resolved] Replacing data in XML file using DOMXML?

[lilleman]

Description

I've recently started to look at the DOMXML extension and I have found it to be very useful. I have no problems to create a new XML file or read data from an existing one. So, why am I here? Well, yesterday I came up with a question that I haven't managed to find an answer to.

First, let us say that I have a XML file that contain this structure.

<?xml version="1.0" encoding="UTF-8" ?>

<friends>

  <friend>
   <name>Eric</name>
   <email>[e-mail]</email>
  </friend>

  <friend>
   <name>James</name>
   <email>[e-mail]</email>
  </friend>

  <friend>
   <name>John</name>
   <email>[e-mail]</email>
  </friend>

</friends>

Question

As you probably know you might get tired of your email after a while and decide to change it. Let's say that James decide to change his email to '[e-mail]'. Is it possible for me to open the XML file and change the email for James using the DOMXML functions?

Thanks in advance!

I got an answer in another forum.

<?php

#- The path to the XML files
$xmlPath = dirName( __FILE__ );

#- Load the file
$dom = domxml_open_file( $xmlPath . '/xml/friends.xml' );

#- Fetch the correct <email> node
$xpc = xpath_new_context($dom);
$result = xpath_eval( $xpc, "//friends/friend[name = 'James']/email" ) or die('fel');

#- Get the node
$email = $result->nodeset;

#- Create the new email and replace the old one
foreach( $email as $i => $node )
{
  $newEmail = $dom->create_text_node('[e-mail]');
  $email[$i]->replace_child( $newEmail, $email[$i]->first_child());
}

#- Print it as an XML file
header('Content-Type: text/xml');
echo $dom->dump_mem();
