xpath在页面中查找特定链接 [英] xpath find specific link in page

问题描述

我正在尝试使用xpath从此页面将电子邮件发送给朋友链接.

I'm trying to get the email to a friend link from this page using xpath.

http://www.guardian .co.uk/education/2009/oct/14/30000-miss-university-place

链接本身被包裹在这样的标签中

The link itself is wrapped up in tags like this

            <li><a class="rollover sendlink" href="http://www.guardian.co.uk/email/354237257"  title="Opens an email form" name="&lid={pageToolbox}{Email a friend}&lpos={pageToolbox}{2}"><img src="http://static.guim.co.uk/static/80163/common/images/icon_email-friend.gif" alt="" class="trail-icon" /><span>Send to a friend</span></a></li>

我正在使用它进行查询，但这不太正确.

I'm using this for my query, but it's not quite right.

            $links = $xpath->query("//a/span[text()='Send to a friend']/@href");

推荐答案

您正在尝试获取该范围的href.我想你想要

You're trying to get the href of the span there. I think you want

$links = $xpath->query("//a[span/text()='Send to a friend']/@href");
