xml::grove::sub

XML::Grove::Sub(3)					User Contributed Perl Documentation					XML::Grove::Sub(3)

NAME

       XML::Grove::Sub - run a filter sub over a grove

SYNOPSIS

	use XML::Grove::Sub;

	# Using filter method on XML::Grove::Document or XML::Grove::Element:
	@results = $grove_object->filter(&sub [, ...]);

	# Using an XML::Grove::Sub instance:
	$filterer = XML::Grove::Sub->new();
	@results = $grove_object->accept($filterer, &sub [, ...]);

DESCRIPTION

       "XML::Grove::Sub" executes a sub, the filter, over all objects in a grove and returns a list of all the return values from the sub.  The
       sub is called with the grove object as it's first parameter and passing the rest of the arguments to the call to `"filter()"' or
       `"accept()"'.

EXAMPLE

       The following filter will return a list of all `"foo"' or `"bar"' elements with an attribute `"widget-no"' beginning with `"A"' or `"B"'.

	 @results = $grove_obj->filter(sub {
	     my $obj = shift;

	     if ($obj->isa('XML::Grove::Element')
		 && (($obj->{Name} eq 'foo')
		     || ($obj->{Name} eq 'bar'))
		 && ($obj->{Attributes}{'widget-no'} =~ /^[AB]/)) {
		 return ($obj);
	     }
	     return ();
	 });
