如下代码如何获得以下内容
使用正则表达式得到<documents>......</documents>中的内容(即得到<documents>以及<documents>之中的内容)
<div class="exp">
<h2><strong>啊啊</strong><a href="#" class="more">更多</a></h2>
<ul>
<documents num="5" ChildID="fswd_low" Length="20" Order="desc_newsid">
<Record><li><a href="<document filed='NewsUrl'>"><document field='Title'></a><span><document field='pTime' Model="Short_time"></span></li></Record>
</documnets>
</ul>
<div class="high">
<h2><strong>办不办</strong><a href="#" class="more">更多</a></h2>
<ul>
<documents num="5" ChildID="fswd_high" Length="21" Order="desc_newsid">
<Record><li><a href="<document field='NewUrl'/>"><document field='Title' /></a><span><document field='pTime' Model="Short_time"></span></li></Record>
</documents>
</ul>
