graph::writer::xml
Graph::Writer::XML(3pm) User Contributed Perl Documentation Graph::Writer::XML(3pm)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.
SEE ALSO
XML::Writer
The perl module used to actually write out the XML. It handles entities etc.
