NAME
       Graph::Writer::XML - write out directed graph as XML


SYNOPSIS
           use Graph;
           use Graph::Writer::XML;

           $graph = Graph->new();
           # add edges and nodes to the graph

           $writer = Graph::Writer::XML->new();
           $writer->write_graph($graph, 'mygraph.xml');


DESCRIPTION
       Graph::Writer::XML is a class for writing out a directed graph in a simple XML format.  The graph must be
       an instance of the Graph class, which is actually a set of classes developed by Jarkko Hietaniemi.

       The XML format is designed to support the Graph classes: it can be used to represent a single graph with
       a collection of nodes, and edges between those nodes.  The graph, nodes, and edges can all have
       attributes specified, where an attribute is a (name,value) pair, with the value being scalar.


METHODS
   new()
       Constructor - generate a new writer instance.

           $writer = Graph::Writer::XML->new();

       This doesn't take any arguments.

   write_graph()
       Write a specific graph to a named file:

           $writer->write_graph($graph, $file);

       The $file argument can either be a filename, or a filehandle for a previously opened file.


KNOWN BUGS
       Attribute values must be scalar. If they're not, well, you're on your own.
