Hello all,
I have a XML

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

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

And I want to add a new node called <value> as

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

<aaa id="b"> 
<a id ="1"> 
<field1> 
[B]<value>[/B]
<field2> 

</a> 
<a id ="2"> 
<field1> 
[B]<value>[/B]
<field2> 

</a> 
..
..
..
..

</aaa> 

</root>

The data to be added in the <value> field is in 2 dimensional array $array[$y][$z]

I tried doing following

$query = "//root/aaa[2]/a/Field2/";
$doc=new domxpath($dom);
$xpath = $doc->query($query);


 foreach($xpath as $node)
   { 

$data= $a[$y][$z];
$refnode=$node;
$parentnode = $refnode->parentNode;
$newnode = $dom->createElement('value',$data);
$newnode = $parentnode->insertbefore($newnode, $refnode);

}
   $y++;
 }
 $z++;
 $y=1;	   

}

but the loop for counter $y,$z does not works with loop for the Xpath, and so I am not able to put in right data at right<value> tag.Can some one help me with the loop please...

Regards,
Thanks in advance

What doesn't work? Are you getting any error messages? I've found that it's somewhat common that the DOM library isn't always installed - you should check to make sure it is installed (although an error message would tell you this - 'function not found').

Also, please wrap your code in the built-in php tags...rough on the eyes.

Hello,

I have DOM properly installed and working fine. Problem is with the loop, I am not able to put in correct elements from my array $a[$y][$z] into correct positions.
What happens is that the loop for the variables $y and $z and loop for Xpath together does not give the desired results.
I have array of data as follows

$y $z value

1 1 10
1 2 20
. ..
. ..

1 8
2 1
..
..
3 1
..
..
5 8

and in the loop I want the array loop to work in such a way so that for first value tag it attaches under <aaa id="b"> it attaches value $a[1][1],
for second tag a[2][1]
for third tag a[3][1]
a[4][1]
a[5][1]

Thanks in advance
Regards,
