[PHP]
use XML: Smiley Very Happy

OM;

use XML: Smiley Tongue

arser;

my $file = "test.xml";

my $parser = new XML: Smiley Very Happy

OM:

arser;
my $doc = $parser->parsefile($file);

my $nodes = $doc->getElementsByTagName("product");
my $node = $nodes->item(0);
my $valueOfID = $node->getAttributeNode("id");
my $valID = $valueOfID->getValue;

# $node->setAttribute("id","abc");

[/PHP]

but findind it difficult to set the value to the id attribute of the product node

What would happen if you uncomment the last line in the code?

thanks Ronald ,

Nothing , it does nothing to the XML file. I put it to test if it sets the attribute value but in vain Smiley Sad

Ah, now i see what you mean.

Setting the attribute changes the in-memory-dom. But not the actual file. You will have to write the resulting xml to the file to do that. See the example in the perldoc of the DOM module for how to.
