Graph::Reader::XML - class for reading a Graph instance from XML
use Graph::Reader::XML; use Graph; $reader = Graph::Reader::XML->new(); $graph = $reader->read_graph('mygraph.xml');
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.
Constructor - generate a new reader instance.
$reader = Graph::Reader::XML->new();
This doesn't take any arguments.

$graph = $reader->read_graph( $file );
$file argument can be either a filename or a filehandle of a previously opened file.
Attribute values must be scalar. If they're not, well, you're on your own.
