The libogg library manipulates the ogg multimedia container format, which encapsulates raw compressed data and allows the interleaving of audio and video data. In addition to encapsulation and interleaving of multiple data streams, ogg provides packet framing, error detection, and periodic timestamps for seeking.

FLAC stands for Free Lossless Audio Codec, an audio format that is lossless, meaning that audio is compressed in FLAC without any loss in quality.

This module provides a class to handle the SOAP protocol. The first implementation is http://www.w3.org/TR/2000/NOTE-SOAP-20000508/, which is still most often used.

XML::RegExp contains regular expressions for the following XML tokens: BaseChar, Ideographic, Letter, Digit, Extender, CombiningChar, NameChar, EntityRef, CharRef, Reference, Name, NmToken, and AttValue.

Libxslt is an XSLT C library developed for the GNOME project. It is based on libxml for XML parsing, tree manipulation and XPath support.

The conventional models for parsing XML are either DOM (a data structure representing the entire document tree is created) or SAX (callbacks are issued for each element in the XML).

XML grammar is recursive - so it's nice to be able to write recursive parsers for it. XML::Descent allows such parsers to be created.

This module provides an XPath engine, that can be re-used by other module/classes that implement trees. It is designed to be compatible with Class::XPath, ie it passes its tests if you replace Class::XPath by Tree::XPathEngine.

PyXB-X ("pixbix") is a pure Python package that generates Python source code for classes that correspond to data structures defined by XMLSchema.

TinyXML is a small and simple XML parsing library for the C++ programming language.

This module understands WSDL version 1.1. A WSDL file defines a set of messages to be send and received over SOAP connections. This involves encoding of the message to be send into XML, sending the message to the server, collect the answer, and finally decoding the XML to Perl.

pugixml is a C++ XML processing library, which consists of a DOM-like interface with rich traversal/modification capabilities, a fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with Unicode interface variants and conversions between different Unicode encodings which happen automatically during parsing/saving.

The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt.

Libxmlb library takes XML source, and converts it to a structured binary representation with a deduplicated string table; where the strings have the NULs included. This allows an application to mmap the binary XML file, do an XPath query and return some strings without actually parsing the entire document.

TinyXML2 is a small and simple XML parsing library for the C++ programming language.

Atom is a syndication, API, and archiving format for weblogs and other data. XML::Atom implements the feed format as well as a client for the API.

XML::SAX consists of several framework classes for using and building Perl SAX2 XML parsers, filters, and drivers.

This module provides an XPath engine, that can be re-used by other modules/classes that implement trees.

In order to use the XPath engine, nodes in the user module need to mimic DOM nodes. The degree of similitude between the user tree and a DOM dictates how much of the XPath features can be used. A module implementing all of the DOM should be able to use this module very easily (you might need to add the cmp method on nodes in order to get ordered result sets).

This package provides a Cleaner for cleaning up HTML pages. It supports removing embedded or script content, special tags and CSS style annotations among other features. Its main purpose is removing superfluous content, it is not appropriate for security sensitive environments.

Libxml2 is the XML C parser and toolkit developed for the Gnome project (but it is usable outside of the Gnome platform).

FreeXL is a C library to extract valid data from within an Excel (.xls, .xlsx) or LibreOffice (.ods) spreadsheet.

This package provides an XML Schema and its catalog. The schema constrains the syntax of xml:lang, xml:spec, xml:base, and xml:id in the schema language defined by the XML Schema Recommendation Second Edition of 28 October 2004.

This module provides ways to parse XML documents. It is built on top of XML::Parser::Expat, which is a lower level interface to James Clark's expat library. Each call to one of the parsing methods creates a new instance of XML::Parser::Expat which is then used to parse the document. Expat options may be provided when the XML::Parser object is created. These options are then passed on to the Expat object on each parse call. They can also be given as extra arguments to the parse methods, in which case they override options given at XML::Parser creation time.

XLSX I/O aims to provide a C library for reading and writing .xlsx files. The .xlsx file format is the native format used by Microsoft(R) Excel(TM) since version 2007.

This package provides methods to cache compiled XML translators.
