OpenSP is an object-oriented toolkit for SGML parsing and entity management. It is a fork of James Clark's SP suite. The tools it contains can be used to parse, validate, and normalize SGML and XML files. The central program included in this package is onsgmls, which replaces sgmls, ospam, ospent, osgmlnorm, and osx.

A collection of smaller Perl modules, scripts, and documents for working with XML in Perl. libxml-perl software works in combination with XML::Parser, PerlSAX, XML::DOM, XML::Grove, and others.

HTML-XML-utils provides a number of simple utilities for manipulating and converting HTML and XML files in various ways. The suite consists of the following tools:

• asc2xml convert from UTF-8 to &#nnn; entities

• xml2asc convert from &#nnn; entities to UTF-8

• hxaddid add IDs to selected elements

• hxcite replace bibliographic references by hyperlinks

• hxcite mkbib - expand references and create bibliography

• hxclean apply heuristics to correct an HTML file

• hxcopy copy an HTML file while preserving relative links

• hxcount count elements and attributes in HTML or XML files

• hxextract extract selected elements

• hxincl expand included HTML or XML files

• hxindex create an alphabetically sorted index

• hxmkbib create bibliography from a template

• hxmultitoc create a table of contents for a set of HTML files

• hxname2id move some ID= or NAME= from A elements to their parents

• hxnormalize pretty-print an HTML file

• hxnsxml convert output of hxxmlns back to normal XML

• hxnum number section headings in an HTML file

• hxpipe convert XML to a format easier to parse with Perl or AWK

• hxprintlinks number links and add table of URLs at end of an HTML file

• hxprune remove marked elements from an HTML file

• hxref generate cross-references

• hxselect extract elements that match a (CSS) selector

• hxtoc insert a table of contents in an HTML file

• hxuncdata replace CDATA sections by character entities

• hxunent replace HTML predefined character entities to UTF-8

• hxunpipe convert output of pipe back to XML format

• hxunxmlns replace "global names" by XML Namespace prefixes

• hxwls list links in an HTML file

• hxxmlns replace XML Namespace prefixes by "global names"

This is an XML writer that understands SAX2. It is based on XML::Handler::YAWriter.

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.

This module implements a Perl interface to the libxml2 library which provides interfaces for parsing and manipulating XML files. This module allows Perl programmers to make use of the highly capable validating XML parser and the high performance DOM implementation.

The XML::Compile module suite has extensive regression testing. This module provide functions which simplify writing tests for XML::Compile related distributions.

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

XML::Twig is an XML transformation module. Its strong points: can be used to process huge documents while still being in tree mode; not bound by DOM or SAX, so it is very perlish and offers a very comprehensive set of methods; simple to use; DWIMs as much as possible.

What it doesn't offer: full SAX support (it can export SAX, but only reads XML), full XPath support (unless you use XML::Twig::XPath), nor DOM support.

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.

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.

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

This is a very simple filter. One common cause of grief (and programmer error) is that XML parsers aren't required to provide character events in one chunk. They can, but are not forced to, and most don't. This filter does the trivial but oft-repeated task of putting all characters into a single event.

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

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.

Defusedxml provides XML bomb protection for Python stdlib modules.

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.

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 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.

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).

XML::TokeParser provides a procedural ("pull mode") interface to XML::Parser in much the same way that Gisle Aas' HTML::TokeParser provides a procedural interface to HTML::Parser. XML::TokeParser splits its XML input up into "tokens", each corresponding to an XML::Parser event.

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.

Xmlto is a front-end to an XSL toolchain. It chooses an appropriate stylesheet for the conversion you want and applies it using an external XSL-T processor. It also performs any necessary post-processing.
