NAME

       GraphViz::XML - Visualise XML as a tree

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).
