Description:

Hi folks,

I just downloaded development version av PHP 5 (CVS 2003-11-02) and tried the new DOM functions that uses libxml2 library. It's working great but there is one thing that I don't understand.

I tried to update a xml file I have and I can add nodes and attributes but when i try to save file then nothing happens. There is no error messages at all.

How ever if I choose another file name for the save function then it is working. New file is created and I see both the old and the new nodes in the xml file.

Am I missing something here?

Reproduce code:
---------------
<?php
    echo "<h3>Just a simple DOM test</h3>";

    $dom = new domDocument();
    $load = $dom->load('test.xml');
    $root = $dom->documentElement;

    $element = $dom->createElement("temp", "Just a test text");
    $attr = $element->setAttribute("id", "0007");
    $attr = $element->setAttribute("author", "darren");
    $tmp = $root->appendChild($element);

    $tmp = $dom->save('test.xml');
    echo $tmp." bytes was saved to the xml file.";
?>

Expected result:
----------------
The file should be updated. Output i my browser should be:

363 bytes was saved to the xml file.

Actual result:
--------------
0 bytes was saved to the xml file.
