Change manifest.plist values in PHP

Question

I have a manifest.plist file (come from Apple). This is an XML file. Here's an exemple of the structure :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>id</key>
    <string>3214</string>
    <key>name</key>
    <dict>
      <key>en</key>
      <string>Hello World</string>
      <key>jp</key>
      <string>Hello World JP</string>
    </dict>
    <key>kilometers</key>
    <integer>430</integer>
    <key>cloud</key>
    <true/>
  </dict>
</plist>

I can get this XML as object with simplexml. Now I would like to change some values in my XML (e.g cloud to false of jp string value).

OK, but what is your question? Is it just how to edit the XML? Then searching `php edit xml` will give you everything you need — Pekka, Mar 08 '13 at 10:36
Now I tried with DOMElement and Xpath query '/plist/dict/key[4]' to get the cloud key. But How can change its value to false ? — Pierre, Mar 08 '13 at 11:02

Now I tried with DOMElement and Xpath query '/plist/dict/key[4]' to get the cloud key. But How can change its value to false ?

The element you talk about is here:

    <key>cloud</key>
    <true/>

And you want to change from <true/> to <false/>. However that is not changing the value but replacing the <true/> element node with a new node, a <false/> element node.

This is not (really) possible with SimpleXML because it can not replace nodes.

With DomDocument you can do it with the DOMNode::replaceChild()^Docs function.

An example:

Let's assume you have the variable $key and it is the <key> element you've fetched via xpath.

$true  = $key->nextSibling;
$false = $key->ownerDocument->createElement('false');
$key->parentNode->replaceChild($false, $true);
