Xerces-C++ is a validating XML parser written in a portable subset of C++. Xerces-C++ makes it easy to give your application the ability to read and write XML data. A shared library is provided for parsing, generating, manipulating, and validating XML documents using the DOM, SAX, and SAX2 APIs.

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

XML Patch is a C++ library and command-line interface (the xml-diff and xml-patch commands) for patching XML files with XPath expressions.

Expat is an XML parser library written in C. It is a stream-oriented parser in which an application registers handlers for things the parser might find in the XML document (like start tags).

XML::Feed is a syndication feed parser for both RSS and Atom feeds. It also implements feed auto-discovery for finding feeds, given a URI. XML::Feed supports the following syndication feed formats: RSS 0.91, RSS 1.0, RSS 2.0, Atom

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.

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.

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.

This module extends the XML::Parser module by Clark Cooper. The XML::Parser module is built on top of XML::Parser::Expat, which is a lower level interface to James Clark's expat library. XML::DOM::Parser is derived from XML::Parser. It parses XML strings or files and builds a data structure that conforms to the API of the Document Object Model.

This package provides methods to cache compiled XML translators.

The XML Security Library is a C library based on Libxml2. It supports XML security standards such as XML Signature, XML Encryption, Canonical XML (part of Libxml2) and Exclusive Canonical XML (part of Libxml2).

libebml is a C++ library to read and write EBML (Extensible Binary Meta Language) files. EBML was designed to be a simplified binary extension of XML for the purpose of storing and manipulating data in a hierarchical form with variable field lengths.

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

Libxml2-xpath0 is like libxml2 but with a patch applied that provides an --xpath0 option to xmllint that enables it to output XPath results with a null delimiter.

This module aims to comply exactly to the https://www.w3.org/TR/xpath and yet allow extensions to be added in the form of functions. It also provides the command xpath.

The XML Security Library is a C library based on Libxml2. It supports XML security standards such as XML Signature, XML Encryption, Canonical XML (part of Libxml2) and Exclusive Canonical XML (part of Libxml2).

This is a collection of perl classes for reading and writing directed graphs in a variety of file formats. The graphs are represented in Perl using Jarkko Hietaniemi's Graph classes.

There are two base classes. Graph::Reader is the base class for classes which read a graph file and create an instance of the Graph class. Graph::Writer is the base class for classes which take an instance of the Graph class and write it out in a specific file format.

This Perl module is an interface to the GNOME project's libxslt library.

XMLStarlet is a set of command line utilities which can be used to transform, query, validate, and edit XML documents. XPath is used to match and extract data, and elements can be added, deleted or modified using XSLT and EXSLT.

The XML::Simple module provides a simple API layer on top of an underlying XML parsing module (either XML::Parser or one of the SAX2 parser modules).

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

OpenJade is an implementation of Document Style Semantics and Specification Language (DSSSL), a style language to format SGML or XML documents. It contains backends for various formats such as RTF, HTML, TeX, MIF, SGML2SGML, and FOT.

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).

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.
