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](https://libxml-raku.github.io/LibXML-raku/Node)):

  * [LibXML::Namespace](https://libxml-raku.github.io/LibXML-raku/Namespace) - LibXML namespaces (Inherits from [LibXML::Item](https://libxml-raku.github.io/LibXML-raku/Item))

  * [LibXML::Node](https://libxml-raku.github.io/LibXML-raku/Node) - LibXML DOM abstract base node class

  * [LibXML::Text](https://libxml-raku.github.io/LibXML-raku/Text) - LibXML text node class

  * [LibXML::PI](https://libxml-raku.github.io/LibXML-raku/PI) - LibXML DOM processing instruction nodes

See also [LibXML::DOM](https://libxml-raku.github.io/LibXML-raku/DOM), which summarizes DOM classes and methods.

PREREQUISITES
=============

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

Debian/Ubuntu Linux
-------------------

```shell
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
--------

```shell
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).
