SYNOPSIS

         use Weasel::FindExpanders qw( register_find_expander );

         register_find_expander(
           'button',
           'HTML',
           sub {
              my %args = @_;
              $args{text} =~ s/'/''/g; # quote the quotes (XPath 2.0)
              return ".//button[text()='$args{text}']";
           });

         $session->find($session->page, "@button|{text=>\"whatever\"}");

FUNCTIONS

       register_find_expander($pattern_name, $group_name, &expander_function)
           Registers &expander_function as an expander for $pattern_name in $group_name.

           "Weasel::Session" selects the expanders to be applied using its "groups" attribute.

       expand_finder_pattern($pattern, $args, $groups)
           Returns a string of concatenated (using xpath '|' operator) expansions.

           When $groups is undef, all groups will be searched for "pattern_name".

           If the pattern doesn't match '*<pattern_name>|{<arguments>}', the pattern is returned
           as the only list/arrayref element.
