NAME

       Test::XML::Twig - Test XML::Twig handlers

SYNOPSIS

         use Test::XML::Twig tests => 2;
         use My::Twig qw( handler );

         test_twig_handler(
             \&handler,
             '<foo/>', '<bar/>',
             'turns foo to bar',
         );

         test_twig_handlers(
             { twig_handlers => { 'foo' => \&handler } },
             '<foo/>', '<bar/>',
             'turns foo into bar',
         );

DESCRIPTION

       This module is for testing XML::Twig handlers.

FUNCTIONS

       All functions are exported.

       get_twig ( INPUT [, ARGS ] )
           Return a parsed twig of INPUT, or undef on parse failure.  Optionally, ARGS may be
           supplied as a set of hash-like parameters to be passed into the twig constructor.

       test_twig_handler ( HANDLER, INPUT, EXPECTED, TESTNAME [, COND ] )
           Parse INPUT, using HANDLER as a twig_handler (i.e: it gets called after the parse tree
           has been built).  Tests that the result is the same as EXPECTED (which can be either a
           string of XML or a quoted regex).  HANDLER must be a code ref.

           Optionally, COND can be supplied.  Instead of the handler being called with the root
           element of INPUT, COND will be used with first_child() to select an alternative
           element.

           Returns true / false depending upon test success.

       test_twig_handlers ( ARGS, INPUT, EXPECTED, TESTNAME )
           This is similiar to test_twig_handler(), but with more flexibility.  The first
           argument, ARGS, is a hash reference which can be used to specify any of the ordinary
           parameters to twig's constructor.  This lets you test things like start_tag_handlers,
           as well as multiple twig_handlers together.
