# NAME

XML::LibXML::jQuery - Fast, jQuery-like DOM manipulation over XML::LibXML

# SYNOPSIS

use XML::LibXML::jQuery;

my $div = j(<

Hello World


...


...



HTML

$div->find('h1')->text; # Hello World

$div->find('p')->size; # 2

# DESCRIPTION

XML::LibXML::jQuery is a jQuery-like DOM manipulation module build on top of
[XML::LibXML](https://metacpan.org/pod/XML::LibXML) for speed. The goal is to be as fast as possible, and as compatible
as possible with the javascript version of jQuery. Unlike similar modules,
web fetching functionality like `-`append($url)> was intentionally not implemented.

# SIMILAR MODULES

Following is a list of similar CPAN modules.

- Web::Query::LibXML

[Web::Query::LibXML](https://metacpan.org/pod/Web::Query::LibXML) is my previous attempt to create a fast, jQuery-like module.
But since it uses [HTML::TreeBuilder::LibXML](https://metacpan.org/pod/HTML::TreeBuilder::LibXML) (for compatibility with [Web::Query](https://metacpan.org/pod/Web::Query))
for the underlying DOM system, its not as fast as if it used XML::LibXML directly.
Also, maintaining it was a bit of a pain because of the API contracts to [Web::Query](https://metacpan.org/pod/Web::Query)
and [HTML::TreeBuilder](https://metacpan.org/pod/HTML::TreeBuilder).

- jQuery

[jQuery](https://metacpan.org/pod/jQuery) seemed to be the perfect candidade for me to use/contribute since its
a jQuery port implemented directly over XML::LibXML, but discarded the idea after
finding some issues. It was slower than Web::Query::LibXML for some methods, it
has its own css selector engine (whose code was a bit scary, I'd rather just
use HTML::Selector::XPath), invalid html output (spits xml) and even some broken
methods. Which obviously could be fixed, but honestly I didn't find its codebase
fun to work on.

- Web::Query

[Web::Query](https://metacpan.org/pod/Web::Query) uses the pure perl DOM implementation [HTML::TreeBuilder](https://metacpan.org/pod/HTML::TreeBuilder), so its
slow.

- pQuery

[pQuery](https://metacpan.org/pod/pQuery) is also built on top of [HTML::TreeBuilder](https://metacpan.org/pod/HTML::TreeBuilder), so..

# CONSTRUCTOR

A shortcut to [new](https://metacpan.org/pod/new).

# METHODS

Unless otherwise noted, all methods behave exactly like the javascript version.
