.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is for testing XML::Twig handlers.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
All functions are exported.
.IP "get_twig ( \s-1INPUT\s0 [, \s-1ARGS\s0 ] )" 4
.IX Item "get_twig ( INPUT [, ARGS ] )"
Return a parsed twig of \s-1INPUT,\s0 or undef on parse failure. Optionally,
\&\s-1ARGS\s0 may be supplied as a set of hash-like parameters to be passed into
the twig constructor.
.IP "test_twig_handler ( \s-1HANDLER, INPUT, EXPECTED, TESTNAME\s0 [, \s-1COND\s0 ] )" 4
.IX Item "test_twig_handler ( HANDLER, INPUT, EXPECTED, TESTNAME [, COND ] )"
Parse \s-1INPUT,\s0 using \s-1HANDLER\s0 as a \fItwig_handler\fR (i.e: it gets called
after the parse tree has been built). Tests that the result is the same
as \s-1EXPECTED\s0 (which can be either a string of \s-1XML\s0 or a quoted regex).
\&\s-1HANDLER\s0 must be a code ref.
.Sp
Optionally, \s-1COND\s0 can be supplied. Instead of the handler being called
with the root element of \s-1INPUT, COND\s0 will be used with \fBfirst_child()\fR to
select an alternative element.
.Sp
Returns true / false depending upon test success.
.IP "test_twig_handlers ( \s-1ARGS, INPUT, EXPECTED, TESTNAME\s0 )" 4
.IX Item "test_twig_handlers ( ARGS, INPUT, EXPECTED, TESTNAME )"
This is similiar to \fBtest_twig_handler()\fR, but with more flexibility. The
first argument, \s-1ARGS,\s0 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 \fIstart_tag_handlers\fR, as well as multiple
\&\fItwig_handler\fRs together.
