Graph::Writer::XML(3pm)

Usage

    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');

Overview

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.
