NAME

       XML::Easy - XML processing with a clean interface

SYNOPSIS

           use XML::Easy::NodeBasics qw(xml_element xml_e_attribute);
           use XML::Easy::Text qw(xml10_read_document xml10_write_document);

           $element = xml_element("a", { href => "there" }, "there");
           $element = xml10_read_document('<a href="there">there</a>');

           $href = xml_e_attribute($element, "href");
           $text = xml10_write_document($element);

DESCRIPTION

       XML::Easy is a collection of modules relating to the processing, parsing, and serialisation of XML data.
       It is oriented towards the use of XML to represent data for interchange purposes, rather than the use of
       XML as markup of principally textual data.  It does not perform any schema processing, and does not
       interpret DTDs or any other kind of schema.  It adheres strictly to the XML specification, in all its
       awkward details, except for the aforementioned DTDs.

       XML::Easy strictly separates the in-program manipulation of XML data from the processing of the textual
       form of XML.  This shields the XML user from the inconvenient and obscure aspects of XML syntax.  XML
       data nodes are mainly processed in a clean functional style, using the XML::Easy::NodeBasics module.  In
       the (very likely) event that an application requires some more purpose-specific XML data processing
       facilities, they are readily built on top of XML::Easy::NodeBasics, retaining the abstraction from
       textual XML.

       When XML must be handled in textual form, for input and output, the XML::Easy::Text module supplies a
       parser and a serialiser.  The interfaces here, too, are functional in nature.

       There are other modules for some ancillary aspects of XML processing.

MODULES

       The modules in the XML::Easy distribution are:

       XML::Easy
           This document.  For historical reasons, this can also be loaded as a module, and (though it is
           deprecated) some of the functions from XML::Easy::Text can be imported from here.

       XML::Easy::Classify
           This module provides various type-testing functions, relating to data types used in the XML::Easy
           ensemble.  These are mainly intended to be used to enforce validity of data being processed by XML-
           related functions.

       XML::Easy::Content
       XML::Easy::Element
           These are classes used to represent XML data for general manipulation.  Objects of these classes hold
           the meaningful content of the data, independent of textual representation.  The data in these nodes
           cannot be modified: different data requires new nodes.

       XML::Easy::NodeBasics
           This module supplies functions concerned with the creation, examination, and other manipulation of
           XML data nodes (content chunks and elements).  The nodes are dumb data objects, best manipulated
           using plain functions such as the ones in this module.

       XML::Easy::Syntax
           This module supplies Perl regular expressions describing the grammar of XML 1.0.  This is intended to
           support doing irregular things with XML, rather than for normal parsing.

       XML::Easy::Text
           This module supplies functions that parse and serialise XML data as text according to the XML 1.0
           specification.

OTHER DISTRIBUTIONS

       Other CPAN distributions that work with XML::Easy are:

       Test::XML::Easy
           A testing tool, providing Test::More-style functions that check whether XML nodes are as expected.

       XML::Easy::ProceduralWriter
           Provides a way to construct XML data nodes by procedural code.  Some programmers will find this more
           comfortable than the functional style offered by XML::Easy::NodeBasics.

       XML::Easy::SimpleSchemaUtil
           Helps to parse things that are encoded in XML in common ways.

       "XML::Easy::Transform::"
           This namespace exists to contain modules that perform transformations on XML documents, or parts
           thereof, in the form of XML::Easy::Element and XML::Easy::Content nodes.
