XML::DT is a package for down translation of XML files.

SYNOPSIS

use XML::DT;

%xml=( music => sub{"Music from: $cn"},
lyrics => sub{"Lyrics from: $v{name}n"},
title => sub{ uc($c) },
-default => sub{"$q:$c"} );

print dt($filename,%xml);

ABSTRACT

This module is a XML down processor. It maps tag (element) names to functions to process that element and respective contents.

This module processes XML files with an approach similar to OMNIMARK. As XML parser it uses XML::Parser or XML::LibXML module in an independent way. At configure stage, you should choose one of the back-ends.

XML::QL is an XML query language.

SYNOPSIS

$ql = WHERE $head ORDER-BY $head IN "file:REC-xml-19980210.xml" CONSTRUCT $head;

print XML::QL->query($sql);

This module is an early implementation of a note published by the W3C called "XML-QL: A Query Language for XML". XML-QL allows the user to query an XML document much like a database, and describe a construct for output. Currently this module only offers partial functionality as described in the specification, and even some of that has been changed for ease of use. This documentation will describe the fuctionality of this module as well as differences from the XML-QL specification.

METHODS

query( "query" )

This is the only method required to use this module. This one method allows the user to pass a valid XML-QL query to the module, and the return value is the output.

Pod::XML is a Perl module to convert POD to XML.

SYNOPSIS

use Pod::XML;
my $parser = Pod::XML->new();
$parser->parse_from_file("foo.pod");

This module uses Pod::Parser to parse POD and generates XML from the resulting parse stream. It uses its own format, described below.

XML::SAX is a simple API for XML.

SYNOPSIS

use XML::SAX;

# get a list of known parsers
my $parsers = XML::SAX->parsers();

# add/update a parser
XML::SAX->add_parser(q(XML::SAX::PurePerl));

# remove parser
XML::SAX->remove_parser(q(XML::SAX::Foodelberry));

# save parsers
XML::SAX->save_parsers();

XML::SAX is a SAX parser access API for Perl. It includes classes and APIs required for implementing SAX drivers, along with a factory class for returning any SAX parser installed on the users system.

XML::DOM is a perl module for building DOM Level 1 compliant document structures.

SYNOPSIS

use XML::DOM;

my $parser = new XML::DOM::Parser;
my $doc = $parser->parsefile ("file.xml");

# print all HREF attributes of all CODEBASE elements
my $nodes = $doc->getElementsByTagName ("CODEBASE");
my $n = $nodes->getLength;

for (my $i = 0; $i < $n; $i++)
{
my $node = $nodes->item ($i);
my $href = $node->getAttributeNode ("HREF");
print $href->getValue . "n";
}

# Print doc file
$doc->printToFile ("out.xml");

# Print to string
print $doc->toString;

# Avoid memory leaks - cleanup circular references for garbage collection
$doc->dispose;

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 Clarks 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 as described at http://www.w3.org/TR/REC-DOM-Level-1. See the XML::Parser manpage for other available features of the XML::DOM::Parser class. Note that the Style property should not be used (it is set internally.)

The XML::Parser NoExpand option is more or less supported, in that it will generate EntityReference objects whenever an entity reference is encountered in character data. Im not sure how useful this is. Any comments are welcome.

As described in the synopsis, when you create an XML::DOM::Parser object, the parse and parsefile methods create an XML::DOM::Document object from the specified input. This Document object can then be examined, modified and written back out to a file or converted to a string.

When using XML::DOM with XML::Parser version 2.19 and up, setting the XML::DOM::Parser option KeepCDATA to 1 will store CDATASections in CDATASection nodes, instead of converting them to Text nodes. Subsequent CDATASection nodes will be merged into one. Let me know if this is a problem.
When using XML::Parser 2.27 and above, you can suppress expansion of parameter entity references (e.g. %pent;) in the DTD, by setting ParseParamEnt to 1 and ExpandParamEnt to 0. See Hidden Nodes for details.

A Document has a tree structure consisting of Node objects. A Node may contain other nodes, depending on its type. A Document may have Element, Text, Comment, and CDATASection nodes. Element nodes may have Attr, Element, Text, Comment, and CDATASection nodes. The other nodes may not have any child nodes.

This module adds several node types that are not part of the DOM spec (yet.) These are: ElementDecl (for < !ELEMENT ... > declarations), AttlistDecl (for < !ATTLIST ... > declarations), XMLDecl (for < ?xml ...? > declarations) and AttDef (for attribute definitions in an AttlistDecl.)

Bare XML project is a XML parser with all primary parsing done via a simple state engine with about 20 or so different states. A tree structure is created during parsing, with all node names and values linked via pointers directly into the original text buffer.

As such, Bare XML is extremely fast and simple. Currently, the parser is available in a perl module with Perl glue to turn the created tree into a Perl hash tree. The module name is XML::Bare.

XML::RSS is a Perl module that creates and updates RSS files.

This module provides a basic framework for creating and maintaining RDF Site Summary (RSS) files. This distribution also contains many examples that allow you to generate HTML from an RSS, convert between 0.9, 0.91, and 1.0 version, and other nifty things. This might be helpful if you want to include news feeds on your Web site from sources like Slashot and Freshmeat or if you want to syndicate your own content.

XML::RSS currently supports 0.9, 0.91, and 1.0 versions of RSS. See http://my.netscape.com/publish/help/mnn20/quickstart.html for information on RSS 0.91. See http://my.netscape.com/publish/help/ for RSS 0.9. See http://purl.org/rss/1.0/ for RSS 1.0.

RSS was originally developed by Netscape as the format for Netscape Netcenter channels, however, many Web sites have since adopted it as a simple syndication format. With the advent of RSS 1.0, users are now able to syndication many different kinds of content including news headlines, threaded measages, products catalogs, etc.
