这种正则表达式怎么写?求高手解答!
有一个网页中的代码如下:

<span class="1"><br />      <h3 class="title">testtesttesttesttesttestt</h3><br />      <div class="con"><br />            <span>testtesttest</span><p>testtesttesttesttesttesttesttesttest</p><br />      </div><br /></span><br /><div class="2"><br />      <h3 class="title">testtesttesttesttesttestt</h3><br />      <div class="con"><br />            <span>testtesttest</span><p>testtesttesttesttesttesttesttesttest</p><br />      </div><br /></div><br /><div class="3"><br />      <h3 class="title">testtesttesttesttesttestt</h3><br />      <div class="con"><br />            <span>testtesttest</span><p>testtesttesttesttesttesttesttesttest</p><br />      </div><br /></div><br /><span class="4"><br />      <h3 class="title">testtesttesttesttesttestt</h3><br />      <div class="con"><br />            <span>testtesttest</span><p>testtesttesttesttesttesttesttesttest</p><br />      </div><br /></span><br />...
Copy after login

大家注意到没有 class="1",class="2",class="3",...是有规律的,但是前面的标签没有规律,有时是span,有时是div,我想要的是用php如何写正则表达式获取class="1",class="2",class="3",...的内容,正则表达式这方面学的不好,试了半天都写不出来,求高手解答!
