Query into xinclude (included xml) using xpath

Hi,

I have 2 xmls; main.xml and child.xml. child.xml is included in main.xml using xinclude. attribute values in child.xml internally refer to value of attribute in main.xml. sample files are as below.

main.xml

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<mainroot>
    <xi:include href="child.xml"/>
    <path name="mypath" value="C:\Work"></path>
</mainroot>

child.xml

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<childroot>
    <childelement processname="myprocess" process_input_file="${[//dir@mypath]}/myinputfile.txt"></childelement>
</childroot>

Since child.xml is included in main.xml, i thought i could write the following code to get the value of "process_input_file".

Code:

#!/usr/bin/perl
use XML::XPath;
my $xp = XML::XPath->new(filename => 'c:/main.xml');
my $nodeset = $xp->find('//mainroot/childroot/childelement');
foreach my $node ($nodeset->get_nodelist) {
  $processname = "".$node->find('@processname');
  $processinputfile = "".$node->find('@process_input_file');
  if ($processname eq "myprocess") {
    print "processinputfile=$processinputfile\n";
  }
}

But it doesn't work. Can I query into included xml file through the parent xml (here main.xml) using xpath? If not, is there an alternative?

Thanks
Sajith
