PHP - Update an XML attribute

I'm trying to update XML document. I start with a string that contains XML.

I'm loading that string to SimpleXMLElement object:

$xmlDoc = simplexml_load_string($my_xml_string);

I find a node that I would like to update like so:

$node= $xmlDoc->xpath("//nodename[@node_attribute='{$search_attribute_value}']");

Now I would like to update the node_attribute attribute. I try to do $node['node_attribute']=$new_attribute_value however $node is it's own object and this doesn't update the $xmlDoc object.

How do I find and update attribute value in the $xmlDoc?

Untested, but you should try like this.

$nodename->attributes()->node_attribute = $new_attribute_value;

The $node you have there is actually an array of nodes. If you know you've only got one to update you can:

$node[0]['node_attribute'] = $new_attribute_value;

More appropriate may be:

$nodes = $xmlDoc->xpath("//nodename[@node_attribute='{$search_attribute_value}']");
foreach ($nodes as $node) {
    $node['node_attribute'] = $new_attribute_value;
}

And everything will be updated as expected.
