The Comprehensive Perl Archive Network (CPAN), is a wonderful place, packed to the brim with all manner
of goodies for Perl programmers. A little rummaging around, and you’ll
uncover ready-made widgets for everything from text processing to socket
programming. And one category CPAN
is particularly strong in is XML, especially as more and more people have begun
integrating XML into their applications.

If you’re one of those people, keep reading, because this
document lists ten CPAN modules that you’re sure to find helpful in your daily
development activities.

Note: You can
install CPAN modules directly from
the Internet; just follow the provided instructions

XML::Parser

This
module provides an interface to the expat XML parser.
It is one of the core Perl modules for XML parsing, and many of the other
packages in this list depend on it. It uses the SAX approach to XML parsing,
wherein different handlers are defined for the various types of XML elements
in a document.

Use this
module when you need to process an XML document using SAX.

XML::Parser

XML::DOM

This
module represents XML data as a Document Object Model (DOM) tree, and makes
available methods and properties to navigate and manipulate the tree and its
contents. It can be used to both parse existing trees or to dynamically
create new trees from scratch.

Use this
module when you need to process an XML document using the DOM.

XML::DOM

XML::XSLT

This
module implements the XSLT specification, making it possible to
“transform” an XML document as per specific style sheet rules,

Use this
module to convert XML-encoded data into some other format using an XSLT style
sheet.

XML::XSLT

XML::XPath

This
module provides an XPath implementation, making it
possible to address XML nodes or node collections through the use of XPath expressions.

Use this
module when you need to create custom node collections or capture nodes
matching complex criteria.

XML::XPath

XML::Simple

This
module simplifies the task of accessing individual nodes, attributes and
other entities in an XML document, by representing the document as a
hierarchical object tree. Individual elements of the document are accessed
transparently using standard object notation.

Use this
module to efficientlyÂ
extract information from XML documents, without the complexity
of SAX or the overhead of DOM.

XML::Simple

XML::RSS::Parser

This
module provides an object-oriented interface to parse RSS feeds. It extracts
information from an RSS feed as an object, and lets you access individual
elements of the feed as object properties.

Use this
module when you need to parse RSS metadata.

XML::RSS::Parser

XML::Dumper

This
module lets you convert Perl variables and structures into XML format, and
vice-versa.

Use this
module if you need to convert between Perl and XML structures, usually for
compatibility or interoperability between different applications.

XML::Dumper

WDDX

This
module lets you create serialized language- and platform-independent
representations of data, for easier data exchange.

Use this
module when you need to share data between applications written in different
languages or running on different platforms.

WDDX

XML::EasySQL

This
module serves as a translator between XML and SQL. It allows you to transform
SQL data into XML, alter it using an XML path interface, and then save the
changes back to the database in SQL.

Use this
module when you need to convert XML data to database-compliant format, or
vice-versa.

XML::EasySQL

XML::LibXML

This
module provides a full-featured interface to the GNOME libxml2 library, a fast and efficient
tool that is gradually becoming the de facto standard for XML parsing on
*NIX. Both DOM and SAX are supported.

Use this
module when your application needs to interface with libxml2, usually to use
its pre-built parsing routines.

XML::LibXML
