Trouble Parsing XML File Using Perl

[akziag69]

I'm trying to parse an XML manifest file for an Articulate eLearning course (imsmanifest.xml).An excerpt of the XML structure is provided below (I'm trying to drill down to adlcp:masteryscore):\[code\]<?xml version="1.0" encoding="UTF-8"?><manifest xsi:schemaLocation="http://www.imsproject.org/xsd/imscp_rootv1p1p2 imscp_rootv1p1p2.xsd http://www.imsglobal.org/xsd/imsmd_rootv1p2p1 imsmd_rootv1p2p1.xsd http://www.adlnet.org/xsd/adlcp_rootv1p2 adlcp_rootv1p2.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:adlcp="http://www.adlnet.org/xsd/adlcp_rootv1p2" xmlns="http://www.imsproject.org/xsd/imscp_rootv1p1p2" version="1.0" identifier="Electrical_Design_Part_3"> <metadata/> <organizations default="Electrical_Design_Part_3_ORG"> <organization identifier="Electrical_Design_Part_3_ORG"> <title>Electrical Design - Part 3</title> <item identifier="Electrical_Design_Part_3_SCO" identifierref="Articulate_Presenter_RES" isvisible="true"> <title>Electrical Design - Part 3</title> <adlcp:masteryscore>65</adlcp:masteryscore> </item> </organization> </organizations> <resources/></manifest>\[/code\]I've tried using XML::Simple and XML::LibXML. I can get these modules to work fine with simpler XML files, but not the manifest file I actually need to parse.The following code shows my attempt to use XML::LibXML to drill down to the title tag:\[code\]use XML::LibXML;$filename = "imsmanifest.xml";$parser = XML::LibXML->new();$xmldoc = $parser->parse_file($filename);for my $sample ($xmldoc->findnodes('/manifest/organizations/organization/item/title')) { for my $property ($sample->findnodes('./*')) { print $property->nodeName(), ": ", $property->textContent(), "\n"; } print "\n"; };\[/code\]How does one deal with the colon in the adlcp:masteryscore tag? Whenever I try to use this, I get an error - but maybe I'm not doing it right.Could someone please show me the correct way to drill down to adlcp:masteryscore?Thank you very much.
