简介
如何在php中方便地解析html代码,估计是每个phper都会遇到的问题。用phpQuery就可以让php处理html代码像jQuery一样方便。
项目地址:https://code.google.com/p/phpquery/
github地址:https://github.com/TobiaszCudnik/phpquery
DEMO
下载库文件:https://code.google.com/p/phpquery/downloads/list
我下的是onefile版:phpQuery-0.9.5.386-onefile.zip
官方demo:https://code.google.com/p/phpquery/source/browse/branches/dev/demo.php
然后在项目中引用。
html文件test.html:
<div class=\"thumb\" id=\"Thumb-13164-3640\" style=\"position: absolute; left: 0px; top: 0px;\">
<a href=\"/Spiderman-City-Drive\">
<img src=\"/thumb/12/Spiderman-City-Drive.jpg\" alt=\"\">
<span class=\"GameName\" id=\"GameName-13164-3640\" style=\"display: none;\">Spiderman City Drive</span>
<span class=\"GameRating\" id=\"GameRating-13164-3640\" style=\"display: none;\">
<span style=\"width: 68.14816px;\"></span>
</span>
</a>
</div>
<div class=\"thumb\" id=\"Thumb-13169-5946\" style=\"position: absolute; left: 190px; top: 0px;\">
<a href=\"/Spiderman-City-Raid\">
<img src=\"/thumb/12/Spiderman-City-Raid.jpg\" alt=\"\">
<span class=\"GameName\" id=\"GameName-13169-5946\" style=\"display: none;\">Spiderman - City Raid</span>
<span class=\"GameRating\" id=\"GameRating-13169-5946\" style=\"display: none;\">
<span style=\"width: 67.01152px;\"></span>
</span>
</a>
</div>
php处理:
<?php
include(\'phpQuery-onefile.php\');
$filePath = \'test.html\';
$fileContent = file_get_contents($filePath);
$doc = phpQuery::newDocumentHTML($fileContent);
phpQuery::selectDocument($doc);
$data = array(
\'name\' => array(),
\'href\' => array(),
\'img\' => array()
);
foreach (pq(\'a\') as $t) {
$href = $t -> getAttribute(\'href\');
$data[\'href\'][] = $href;
}
foreach (pq(\'img\') as $img) {
$data[\'img\'][] = $domain . $img -> getAttribute(\'src\');
}
foreach (pq(\'.GameName\') as $name) {
$data[\'name\'][] = $name -> nodeValue;
}
var_dump($data);
?>
上面的代码中包含了取属性和innerText内容(通过nodeValue取)。
输出:
array (size=3)
\'name\' =>
array (size=2)
0 => string \'Spiderman City Drive\' (length=20)
1 => string \'Spiderman - City Raid\' (length=21)
\'href\' =>
array (size=2)
0 => string \'http://www.gahe.com/Spiderman-City-Drive\' (length=40)
1 => string \'http://www.gahe.com/Spiderman-City-Raid\' (length=39)
\'img\' =>
array (size=2)
0 => string \'http://www.gahe.com/thumb/12/Spiderman-City-Drive.jpg\' (length=53)
1 => string \'http://www.gahe.com/thumb/12/Spiderman-City-Raid.jpg\' (length=52)
强大的是pq选择器,语法类似jQuery,很方便。
