phpquery

Automatically exported from code.google.com/p/phpquery 这个是phpquery官方导入过来的，因为原来的代码托管在googlecode上在国内无法访问，所以就同步过来了，使用方法参照下文

Examples

CLI

Fetch number of downloads of all release packages

phpquery 'http://code.google.com/p/phpquery/downloads/list?can=1' \
  --find '.vt.col_4 a' --contents \
  --getString null array_sum
PHP
Examples from demo.php

require('phpQuery/phpQuery.php');
// for PEAR installation use this
// require('phpQuery.php');
INITIALIZE IT
// $doc = phpQuery::newDocumentHTML($markup);
// $doc = phpQuery::newDocumentXML();
// $doc = phpQuery::newDocumentFileXHTML('test.html');
// $doc = phpQuery::newDocumentFilePHP('test.php');
// $doc = phpQuery::newDocument('test.xml', 'application/rss+xml');
// this one defaults to text/html in utf8
$doc = phpQuery::newDocument('<div/>');
FILL IT
// array syntax works like ->find() here
$doc['div']->append('<ul></ul>');
// array set changes inner html
$doc['div ul'] = '<li>1</li><li>2</li><li>3</li>';
MANIPULATE IT
// almost everything can be a chain
$li = null;
$doc['ul > li']
        ->addClass('my-new-class')
        ->filter(':last')
                ->addClass('last-li')
// save it anywhere in the chain
                ->toReference($li);
SELECT DOCUMENT
// pq(); is using selected document as default
phpQuery::selectDocument($doc);
// documents are selected when created or by above method
// query all unordered lists in last selected document
pq('ul')->insertAfter('div');
ITERATE IT
// all LIs from last selected DOM
foreach(pq('li') as $li) {
        // iteration returns PLAIN dom nodes, NOT phpQuery objects
        $tagName = $li->tagName;
        $childNodes = $li->childNodes;
        // so you NEED to wrap it within phpQuery, using pq();
        pq($li)->addClass('my-second-new-class');
}
PRINT OUTPUT
// 1st way
print phpQuery::getDocument($doc->getDocumentID());
// 2nd way
print phpQuery::getDocument(pq('div')->getDocumentID());
// 3rd way
print pq('div')->getDocument();
// 4th way
print $doc->htmlOuter();
// 5th way
print $doc;
// another...
print $doc['ul'];
