Modifying an XML File using Perl

Question

I have an XML file, with some format. I want the data to be modified in some way I want. I feel XML::Twig is the way to do it.

I want to know if there is any other better alternative?

Answer 1

You will probably find the XML::Twig is an ideal tool for the task and there have been plenty of questions/answers on Stack Overflow that seem to reaffirm this:

• In Perl, how can I change an element in an XML file without changing the format of the XML file?
• Can you provide an example of parsing HTML with your favorite parser?
• How can I extract some XML data from a URL using XML::Twig?
• How can I add an attribute to a child element using Perl’s XML::Twig?
• How can I get content using XML::Twig?
• How do I add child elements to XML using Perl’s XML::Twig?

You may also find it helpful to know that the author of XML::Twig does answer questions on this site: Mirod.

However if you really are looking for an alternative then have a look at XML::LibXML. This module is based on libxml2 library (XML::Twig is written on top of XML::Parser which uses the expat library).

Mirod himself lists alternatives to XML::Twig in his FAQ.
