Graph::Reader::XML - class for reading a Graph instance from XMLSYNOPSIS
use Graph::Reader::XML; use Graph; $reader = Graph::Reader::XML->new(); $graph = $reader->read_graph('mygraph.xml');
DESCRIPTION
Graph::Reader::XML is a perl class used to read a directed graph stored as XML, and return an instance of the Graph class.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,
Graph::Reader::XML is a subclass of Graph::Reader, which defines the generic interface for Graph reader classes.
METHODS
