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).
