Name change of cloned node in DOM?

[makingphpwork]

Hello all,
I have a XML as below

<root>
<aaa id="a">
<a id='1'>
<field1> 
<field2>
</a>
<a id="2">
<field1> 
<field2>
</a>
</aaa>

<aaa id="b">
<a id ="ab">
<fielda> 
<fieldb>
</a>
<a id ="pq">
<fielda> 
<fieldb>
</a>
</aaa>
</root>

and I have a PHP code which clones <aaa id=b> node say n times.

Now my problem is I need to add a incremental number to <a id => tag value as below.
For example say if my code clones the <aaa id=b> node 4 times like below

I want to add numbers to the field <a id => as above

<aaa id="b">
<a id ="ab1">
<fielda> 
<fieldb>
</a>
<a id ="pq1">
<fielda> 
<fieldb>
</a>

<a id ="ab2">
<fielda> 
<fieldb>
</a>
<a id ="pq2">
<fielda> 
<fieldb>
</a>

<a id ="ab3">
<fielda> 
<fieldb>
</a>
<a id ="pq3">
<fielda> 
<fieldb>
</a>

<a id ="ab4">
<fielda> 
<fieldb>
</a>
<a id ="pq4">
<fielda> 
<fieldb>
</a>

</aaa>
</root>

Any suggestions..??

Thanks in advance

Hmm, if you want to change something its not really a 'clone' is it ;-)

Anyway, having a quick look-see at php.net you could try something like this:

...
$clonenode = $node->cloneNode(true);   

//and then change the name before you append it, I am just adding your counter.
$clonenode->set_name($clonenode->node_name().$j);
$section->appendChild($clonenode); 
...

that assumes that $node and $clonenode are DomElements, otherwise node_name will return something different. Check function.domnode-node-name.php over at php.net

Good luck.

Tks Shadar,

Both $node and$clonenode are Donelements. On using the above I get the following error

  [[I]B]Fatal error: Call to undefined method DOMElement::set_name() [/B]  [/I] 

Is this because I am using PHP 5 and the set_name etc function are in DOM XML which is in the earlier version..???

If so how can I do this in PHP version 5 or through DOM function

or in other words what the PHP 5 counter part of DomNode->set_name

Thanks in advance
