我得到了div&#34; rso&#34;使用getElementById(&#39; rso&#39;)在php Dom中的数据但是php不允许通过&#34; ClassName&#34; ,我需要得到所有&#34;孩子&#34; <div class =srg>
然后标记&#34; href&#34;在里面。
<div id=”rso”>
<div class= “_Nid”>
<div class = “srg”>
<div class =”g”>
<div class=”rc”>
<h3 class = “r”>
<a href >
</h3>
</div>
</div>
<div class =”g”>...</div>
<div class =”g”>...</div>
<div class =”g”>...</div>
</div>
</div>
</div>
你可以告诉我们如何做到这一点。或者如果它可以在这里工作,将使用什么xPath。
