ios - 获取html中特定标签之间的数据

Question

我想从 html 数据中获取特定标签之间的数据。

<ul>    
    <li>
        More consistent tension control and approximation with each pass than with traditional sutures.
        <ul>                    
            <li>Unique anchor designs provide multiple points of fixation along the device, allowing tension on the device to be maintained during closure.<sup><a class="reference_link" href="#22">[22]</a></sup></li>
            <li>Compared to traditional sutures, STRATAFIX™ Devices enable surgeons to easily manage tension and control approximation with each pass.<sup><a class="reference_link" href="#3">[3]</a></sup></li>
        </ul>
    </li>
<ul>

在这里，我想从 <a class="reference_link" href="#3">[3]</a> 获取数据我想存储该值(例如3)。

提前致谢。

看起来互联网上有关于如何在 iOS 上解析 HTML 的相关资源；例如http://www.raywenderlich.com/14172/how-to-parse-html-on-ios :

[...] there is a handy little library that’s included in the iOS SDK called libxml2.

据我所知，这篇文章似乎有关于如何准确实现您想要的代码示例。
