You are overcomplicating the problem. Do not use setDocumentElement, it creates a new root element. The constructor of XPathContext takes a context node as a parameter, not a file. This is a Short, Self Contained, Correct Example:
#!/usr/bin/perl use warnings; use strict; use XML::LibXML; my $dom = XML::LibXML->load_xml(string => << '__XML__'); <Article> <!-- fixed typo --> <Main> <Sect> <H4>Include</H4> ..... <P1> This is the criteria</P1> <L> <LI> <LI_Label>1.</LI_Label> <LI_Title>Critera 1</LI_Title> </LI> <LI> <LI_Label>2.</LI_Label> <LI_Title>Critera 2</LI_Title> </LI> <LI> <LI_Label>3.</LI_Label> <LI_Title>Critera 3</LI_Title> </LI> <LI> <LI_Label>4.</LI_Label> <LI_Title>Critera 3</LI_Title> </LI> </L> <!-- fixed missing closing tag --> </Sect> </Main> </Article> __XML__ my $xc = XML::LibXML::XPathContext->new; my $count = $xc->findvalue('count(//Article//Sect//LI)', $dom); print "$count list nodes found.\n" if $count;
