      But when I am trying to access the nodes as below I don't get any value.
      print $chapter_node->findvalue('./book:locator/@xlink:href') . "\n";
      Could you please elaborate a bit or point out where I am committing mistake?
        Works for me:
        #!/usr/bin/perl use warnings; use strict; use XML::LibXML; my $xml = XML::LibXML->load_xml(IO => *DATA); my $root = $xml->documentElement; my $chapter_node = $root->findnodes('book:chapter')->[0]; print $chapter_node->findvalue('./book:locator/@*') . "\n"; __DATA__ <book xmlns:book='b'> <!-- Namespace definition missing in the origina +l data --> <book:chapter id="bk444444ch1" type="CHAPTER"> <book:locator xlink:href="/book/isbn/979-0-4444-1000-17/book-part/chap +ter/bk444444ch1?releaseStatus=RELEASED" xlink:title="Photonic crystal + light-emitting sources" xlink:type="locator" xmlns:xlink="http://www +.w3.org/1999/xlink"/> <book:locator xlink:href="/book/isbn/979-0-4444-1000-17/book-part/chap +ter/bk444444ch1?releaseStatus=RELEASED&amp;format=pdf" xlink:title="P +hotonic crystal light-emitting sources" xlink:type="locator" xmlns:xl +ink="http://www.w3.org/1999/xlink"/> <book:locator xlink:href="/book/isbn/979-0-4444-1000-17/book-part/chap +ter/bk444444ch1?releaseStatus=RELEASED&amp;format=epub" xlink:title=" +Photonic crystal light-emitting sources" xlink:type="locator" xmlns:x +link="http://www.w3.org/1999/xlink"/> </book:chapter> <!-- Missing in the original data --> </book>

        Note the changes I made to your data. Maybe your $chapter_node contains something else?

        Well, no, you don't show self-contained code . I guess that you didn't read my nodes and setup xpc with some setns, but I don't really have any way of knowing; also, I hate xml
