[Raku LibXML Project] / [LibXML Module] /

NAME

LibXML - Raku bindings to the libxml2 native library

SYNOPSIS

use LibXML;
use LibXML::Document;
my LibXML::Document $doc .=  parse: :string('<Hello/>');
$doc.root.nodeValue = 'World!';
say $doc.Str;
# <?xml version="1.0" encoding="UTF-8"?>
# <Hello>World!</Hello>
say $doc<Hello>;
# <Hello>World!</Hello>

my Version $library-version = LibXML.version;
my Version $module-version = LibXML.^ver;

DESCRIPTION

This module is an interface to libxml2, providing XML and HTML parsers with DOM, SAX and XMLReader interfaces, a large subset of DOM Layer 3 interface and a XML::XPath-like interface to XPath API of libxml2.

For further information, please check the following documentation:

DOM Objects

The nodes in the Document Object Model (DOM) are represented by the following classes (most of which “inherit” from LibXML::Node):

• LibXML::Document - LibXML DOM document class

• LibXML::Attr - LibXML attribute class

• LibXML::CDATA - LibXML class for DOM CDATA sections

• LibXML::Comment - LibXML class for comment DOM nodes

• LibXML::DocumentFragment - LibXML’s DOM L2 Document Fragment implementation

• LibXML::Dtd - LibXML front-end for DTD validation

• LibXML::Element - LibXML class for element nodes

• LibXML::EntityRef - LibXML class for entity references

• LibXML::Namespace - LibXML namespaces (Inherits from LibXML::Item)

• LibXML::Node - LibXML DOM abstract base node class

• LibXML::Text - LibXML text node class

• LibXML::PI - LibXML DOM processing instruction nodes

See also LibXML::DOM, which summarizes DOM classes and methods.

Container/Mapping classes

• LibXML::Attr::Map - LibXML DOM attribute map class

• LibXML::Node::List - Sibling Node Lists

• LibXML::Node::Set - XPath Node Sets

• LibXML::HashMap - LibXML Hash Bindings

Parsing

• LibXML::Parser - LibXML Parser bindings

• LibXML::PushParser - LibXML Push Parser bindings

• LibXML::Reader - LibXML Reader (pull parser) bindings

SAX Parser

• LibXML::SAX::Builder - Builds SAX callback sets

• LibXML::SAX::Handler::SAX2 - SAX handler base class

• LibXML::SAX::Handler::XML - SAX Handler for XML

XPath and Searching

• LibXML::XPath::Expression - XPath Compiled Expressions

• LibXML::XPath::Context - XPath Evaluation Contexts

• LibXML::Pattern - LibXML Patterns

• LibXML::RegExp - LibXML Regular Expression bindings

Validation

• LibXML::Dtd - LibXML DTD validation class

• LibXML::Schema - LibXML schema validation class

• LibXML::RelaxNG - LibXML RelaxNG validation class

Other

• LibXML::Config - LibXML global and local configuration

• LibXML::Enums - XML_* enumerated constants

• LibXML::Raw - LibXML native interface

• LibXML::ErrorHandling - LibXML class for Error handling

• LibXML::InputCallback - LibXML class for Input callback handling

• See also LibXML::Threads, for notes on threading and concurrency

PREREQUISITES

This module may requires the libxml2 library to be installed. Please follow the instructions below based on your platform:

Debian/Ubuntu Linux

sudo apt-get install libxml2-dev

Additional packages (such as build-essential) may be required to enable make, C compilation and linking.

Mac OS X

brew update
brew install libxml2

The Xcode package also needs to be installed to enable compilation.

Windows

This module uses prebuilt DLLs on Windows. There are currently some configuration (LibXML::Config) restrictions:

• parser-locking is set True to to disable concurrent parsing. This is due to known threading issues and unresolved failures in t/90threads.t

• iconv is False. The library is built without full Unicode support, which restricts the ability to read and write various encoding schemes.

• compression is False. The library is built without full compression, and is unable to read and write compressed XML directly.

ACKNOWLEDGEMENTS

This Raku module:

• is based on the Perl XML::LibXML module; in particular, the test suite, selected XS and C code and documentation.

• derives SelectorQuery() and SelectorQueryAll() methods from the Perl XML::LibXML::QuerySelector module.

• also draws on an earlier attempt at a Perl 6 (nee Raku) port (XML::LibXML).
