Second of all,

XML::Simple

$ perldoc XML::Simple
[download]

#!/usr/bin/perl

use XML::Simple;
use strict;         # use strict, always use strict

$x    = new XML::Simple();
$xref = $x->XMLin('/path/to/xmlfile');

# $xref now stores your xml in a hashref

I strongly suggest you read the docs above though because there are a few attribute options for the <text>XML::Simple</text> object that you will want to at least know about.

You might want to ask a little bit more about the problem before recommending XML::Simple. XML::Simple works great for data-oriented XML, but as soon as you have to deal with documents, that usually include mixed content (<p>this is <b>mixed</b> content</p>: text and sub-elements mixed within an element) then you just can't use it. The content field of the hash can only hold one text, not several as is the case with mixed content.

Plus what if the data to be processed is 4Gb of XML log?

That said there are no tutorials that I am aware of on the Object style of XML::Parser.

Plus XML::Parser is not really the favored way to process XML any more (read it is not actively maintained and its interface is not standard): XML::libXML, or XML::XPath, or (shameless plug!) XML::Twig are good alternatives. Plus of course XML::Simple if your XML is nice enough to fit in it ;--)

Thank you. XML::Simple is good enough for my project.

Just wanted to offer my 10 cents from palying around with HoH (Hash of Hashes) with XML::Dumper / XML::Parser.

Basically didn't play very well with HoH, I use XML::Dumper to output the HoH, but use a custom loader module for the re-reading of the HoH.

It may work well, but I unfortunatly did not find the correct attributes to get it working with HoH.

Plus my little XML database wasn't that hard to make a loader module for.

Best of Luck,
