SYNOPSIS
use GraphViz::XML;
my $graph = GraphViz::XML->new($xml);
print $g->as_png;
DESCRIPTION
This module makes it easy to visualise XML as a tree. XML is hard for
humans to grasp, especially if the XML is computer-generated. This
modules aims to visualise the XML as a graph in order to make the
structure of the XML clear and to aid in understanding the XML.
XML elements are represented as diamond nodes, with links to elements
within them. Character data is represented in round nodes.
Note that the XML::Twig module should be installed.
METHODS
new
This is the constructor. It takes one mandatory argument, which is the
XML to be visualised. A GraphViz object is returned.
my $graph = GraphViz::XML->new($xml);
as_*
The XML can be visualised in a number of different graphical formats.
Methods include as_ps, as_hpgl, as_pcl, as_mif, as_pic, as_gd, as_gd2,
as_gif, as_jpeg, as_png, as_wbmp, as_ismap, as_imap, as_vrml, as_vtx,
as_mp, as_fig, as_svg. See the GraphViz documentation for more
information. The two most common methods are:
# Print out a PNG-format file
print $g->as_png;
# Print out a PostScript-format file
print $g->as_ps;
BUGS
GraphViz tends to reorder the nodes. I hope to find a work around soon
(possibly with ports).
