How to use Zend Dom Query without Zend FW? - php

Question

Is it possible to use Zend Dom Query without Zend Framework?
If yes: Where to download Zend Dom Query and how to use it without Zend Framework?

Answer 1

You can pull out the separate ZF files using some package managers like this one, which will tell what files do you need and will compress them for you. Zend_Dom_Query requires only
Zend/Dom/Query.php
Zend/Dom/Query/Css2Xpath.php
Zend/Dom/Query/Result.php
Zend/Dom/Exception.php
Zend/Exception.php
Anyhow, it's available for download. If there is an urgent need - there are lot of other tools like this one not only for ZF.

Answer 2

The classes in Zend are not meant to be used standalone - is there a reason you cannot have the whole of ZF available but only use Zend_Dom_Query?
Failing that you can get the folder
/library/Dom/
And take it out of the ZF folder, you'll then need to look for any depenancies, having a quick look you will also need:
/library/Exception/Exception.php
Give that a go, let us know how it goes....

Answer 3

I assume by 'without Zend Framework' you mean without using Zend Framework's MVC components. You can use any component of Zend Framework in isolation; it is a glue framework.
Download the library and extract it into your project's library folder or PHP include path. It should then be roughly as simple as the following:
<?php
require_once 'Zend/Dom/Query.php';
$query = new Zend_Dom_Query(....);

It seems to me this approach doesn't work with Zend Framework 2, I don't know why...

Answer 5

You can use zendframework/zend-dom as a standalone component. It has no external dependencies, which means that it doesn't need another Zend component or other library to work.
Alternatively, you could also use a library that is totally unrelated to Zend, like tburry/pquery or my own PHPPowertools/DOM-Query. Both libraries serve the same purpose as zendframework/zend-dom, but syntax is different and HTML5 support may vary for each library.
Example :
This example illustrates how you'd load an HTML string and query for .foo .bar a, with each of these three libraries :
Using zendframework/zend-dom you'd do this :
use \Zend\Dom\Query;
$dom = new Query($htmlcode);
$results = $dom->execute('.foo .bar a');
Using tburry/pquery, you'd do this :
use \pQuery\pQuery
$dom = pQuery::parseStr($htmlcode);
$dom->query('.foo .bar a');
Using PHPPowertools/DOM-Query, you'd do this :
use \PowerTools\DOM_Query
$H = new DOM_Query($htmlcode);
$s = $H->select('.foo .bar a');
Pick your poison!
