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.
