Graph:...r::XML(3pm)

💖 Graph::Writer::XML — the vibe 💖

okay bestie, so this is Graph::Writer::XML(3pm) — a lil page from the User Contributed Perl Documentation corner of the internet, and it's literally here to teach you how to turn a directed graph into XML. no cap. 🦋

---

✨ NAME ✨

Graph::Writer::XML — write out a 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 💅

So Graph::Writer::XML is a class whose whole entire job — its main character moment, if you will — is writing out a directed graph in a simple XML format. 🌈

The graph has to be an instance of the Graph class. and like, that's not just one class, it's actually a whole set of classes developed by Jarkko Hietaniemi. so jot that down. 📝

The XML format is designed to support the Graph classes: it can represent a single graph with a collection of nodes, and edges between those nodes. and the graph, the nodes, and the edges can all have attributes specified — where an attribute is a (name,value) pair, and the value is a scalar. that's the whole deal. ✨

👑 METHODS 👑

💜 new()

Constructor — it makes you a brand new writer instance. 🫶

$writer = Graph::Writer::XML->new();

This one doesn't take any arguments. not a single one. she's low maintenance like that. 🙈

💜 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 file you already opened earlier. your choice bestie, both are valid. 🔥

---

💀 KNOWN BUGS 💀

Attribute values must be scalar. if they're not... well. you're on your own. 😭 no rescue, no lifeline, just vibes and consequences. good luck out there. 🍓

• Graph — Jarkko Hietaniemi's modules for representing directed graphs, available from CPAN under modules/by-module/Graph/. iconic. 👑
• Algorithms in Perl — the O'Reilly book which has a chapter on directed graphs, and that chapter is based around Jarkko's modules. 📚
• Graph::Writer — the base-class for Graph::Writer::XML. her mother, her origin story. 🧚
