XML update with DOM

[xcandiottix]

XML File

<Name N="john">

 

PHP File

$xmltabname = $dom->getElementsByTagName("Name");
$xmltabname->item($i)->textContent = $_POST['tabname'.$i.''];

 

I'm trying to update my XML file, as above I want to change N="john" to $_POST['tabname'.$i.'']. I'm not sure how to construct the second line of the php code. In place of textContent i've tried nodeValue but I'm not hitting the attribute.

 

Can anyone point me the right way?

 

Thanks

Got it. For anyone interested:

$xmltabname = $dom->getElementsByTagName("Name");
$xmltabname->item($i)->textContent = $_POST['tabname'.$i.''];

 

should be:

$xmltabname = $dom->getElementsByTagName("Name");							
$xmltabname->item($i)->setAttribute("N",$_POST['tabname'.$i.'']);

Just a heads up: Things get much more tricky if you have more than one XML element on the page with the attribute "N". If you have a file with a bunch of repeated (nested) XML in it, you will have to first search for a unique value, then perform your search for a particular value or attribute inside of the parent node for that element (the one containing the unique value).
