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. Graph Jarkko Hietaniemi's modules for representing directed graphs, available from CPAN under modules/by-module/Graph/ Algorithms in Perl The O'Reilly book which has a chapter on directed graphs, which is based around Jarkko's modules.
