If you want to search the whole document, you can use `/descendant::Volume[@VolumeCategory="L"]` [download] which can be abbreviated to `//Volume[@VolumeCategory="L"]` [download] Should I understand that that methods does not support attribute? If you're asking if `getElementsByTagName` can filter the returned nodes to retain only those with a specific attribute value, then the answer is no. The only argument it takes is a tag name. You could do `my @matching = grep { my $vc = $_->getAttribute('VolumeCategory'); defined($vc) && $vc eq "L" } $doc->getElementsByTagName('Volume');` [download] but aforementioned `my @matching = $doc->findnodes('//Volume[@VolumeCategory="L"]');` [download] is much simpler.

I think you meant to type… `/descendant::Volume[@VolumeCategory="L"]` With just one colon, you get… `XPath error : Undefined namespace prefix`	[reply] [d/l] [select]
