1、获取页面标题
//提取标题
preg_match('/ (?<title>.*?)<＼/title>/i', $html, $titleArr);<br />
$title = $titleArr['title'];<br />
2、获取body主体内容，并将背景图片提取出来替换成其他图片地址</p>
<p>/**<br />
* 获取BODY主体区域内容<br />
* @param $html<br />
* @param $urlRoot<br />
* @return mixed<br />
*/<br />
function getBody($html,$urlRoot = null){<br />
//提取BODY主体<br />
preg_match('/<!--body-->(.*?)<!--body-->/is ', $html, $bodyArr);<br />
if(!$bodyArr){<br />
preg_match('/<body.*?>(.*?)<＼/body>/is ', $html, $bodyArr);<br />
}<br />
$body = $bodyArr[1];<br />
//替换img文件<br />
$body = preg_replace('/(<[img|IMG].*src=[＼'|"])(＼.＼.＼/)*(img.[^＼'||^"]+)/',"$1$urlRoot$3",$body);<br />
//替换html文件内的css背景图片<br />
$body = preg_replace('~＼b(background(-image)?＼s*:(.*?)＼(＼s*[＼'|"]?)(＼.＼.＼/)*(img.*?)?＼s*＼)~i',"$1$urlRoot$5)",$body);<br />
return $body;<br />
}<br />
3、提取页面Description内容</p>
<p>function getDescription($html){<br />
// Get the 'content' attribute value in a <meta name="description" ... /><br />
$matches = array();<br />
<br />
// Search for <meta name="description" content="Buy my stuff" /><br />
preg_match('/<meta.*?name=("|＼')description("|＼').*?content=("|＼')(.*?)("|＼')/i', $html, $matches);<br />
if (count($matches) > 4) {<br />
return trim($matches[4]);<br />
}<br />
<br />
// Order of attributes could be swapped around: <meta content="Buy my stuff" name="description" /><br />
preg_match('/<meta.*?content=("|＼')(.*?)("|＼').*?name=("|＼')description("|＼')/i', $html, $matches);<br />
if (count($matches) > 2) {<br />
return trim($matches[2]);<br />
}<br />
<br />
// No match<br />
return null;<br />
}<br />
4、替换css文件的背景图片地址</p>
<p>/**<br />
* 获取CSS内容<br />
* @param $cssCnt<br />
* @param $urlRoot<br />
* @return mixed<br />
*/<br />
function getCss($cssCnt,$urlRoot =null){<br />
//匹配包含 img文件夹的相对路径图片 （含义绝对路径的不包含在其中）<br />
//匹配替换不一定准确，因为只是将 含义 ../ 的地址转为url 而没有考虑 ../../ 之类的层级关系<br />
$css = preg_replace('~＼b(background(-image)?＼s*:(.*?)＼(＼s*[＼'|"]?)(＼.＼.＼/)*(img.*?)?＼s*＼)~i',"$1$urlRoot$5)",$cssCnt);<br />
//添加css前缀<br />
$css = preg_replace('/＼b.(.*?)[,|{]/',"pat .$0",$cssCnt);<br />
//TODO 压缩css<br />
return $css;<br />
}</p>

<p>从上面例子来看其实都是非常的简单就是批有规律的标签为开始与结束节点，这样我们可以获取这两个字符之类的内容也就是我们要提取的内容了哦，只是在中间有字符或空格的一些处理了哦。</p></td>
