NAMEGraphViz::XML - Visualise XML as a tree
use GraphViz::XML; my $graph = GraphViz::XML->new($xml); print $g->as_png;
DESCRIPTIONThis module makes it easy to visualise
XMLas a tree.
XMLis hard for humans to grasp, especially if the
XMLis computer-generated. This modules aims to visualise the
XMLas a graph in order to make the structure of the
XMLclear and to aid in understanding the
XMLelements 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.
newThis is the constructor. It takes one mandatory argument, which is the
XMLto be visualised. A GraphViz object is returned.
my $graph = GraphViz::XML->new($xml);
XMLcan 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;
BUGSGraphViz tends to reorder the nodes. I hope to find a work around soon (possibly with ports).
