Given the following XML doc: <?xml version="1.0" encoding="UTF-8"?> <bookstore> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="children"> <title lang="en">Harry Potter</title> <author>J K. Rowling</author> <year>2005</year> <price>29.99</price> </book> <book category="web"> <title lang="en">Learning XML</title> <author>Erik T. Ray</author> <author>James McGovern</author> <year>2003</year> <price>39.95</price> </book> <book category="web"> <title lang="en">XQuery Kick Start</title> <author>Per Bothner</author> <author>James McGovern</author> <author>Kurt Cagle</author> <author>James Linn</author> <author>Vaidyanathan Nagarajan</author> <year>2003</year> <price>49.99</price> </book> </bookstore> If I use the contains() function for books that have an author whose name contains the string McGovern, it works only if McGovern is the first author. Test script below: use strict 'vars'; use IO::Handle; use XML::Simple; use XML::LibXML qw( ); use Data::Dumper; my $parser = XML::LibXML->new(); my $doc = $parser->parse_file('Books.xml'); my @Titles = map {$_->to_literal} $doc->findnodes(q {//book[contains(author, "McGovern")]/title}); # my @Titles = map {$_->to_literal} $doc->findnodes(q {//book[author = "James McGovern"]/title}); print Dumper (@Titles); If I specify an exact match on the full author name, it finds the books.

Probably reading https://stackoverflow.com/questions/1064968/how-to-use-xpath-contains-here helps here. Changing the XPath to //book[./author[contains(.,'McGovern')]]/title seems to return what you want. Regards, Slaven
