<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>SDK 提供了两种解析 XML 的方法:libxml2 和 NSXMLParser。 libxml2 是最快的。要在您的项目中使用它，请转到您的 iPhone App 项目的build设置并设置以下内容:</p>
<ul>
<li><code>其他链接器标志 = -lxml2</code></li>
<li><code> header 搜索路径:$(SDKROOT)/usr/include/libxml2</code></li>
</ul>
<p>然后从这个页面下载 XPathQuery.m 和 XPathQuery.h:<a href="http://cocoawithlove.com/2008/10/using-libxml2-for-parsing-and-xpath.html" rel="noreferrer noopener nofollow">Using libxml2 for XML parsing and XPath queries in Cocoa</a> ，其中还提供了有关如何使用它的教程。 XPathQuery 类是解析 XML 的一种简化方法。我推荐它，除非您想自己编写相同的代码，但事实并非如此。</p>
<p>有了这个，就去做</p>
<pre><code>NSString *string = nil; // put your html document here
NSData *htmlData = ;
NSString *xpath = @"//row"; // any standard XPath expression
NSArray *nodesArray = PerformHTMLXPathQuery(htmlData, xpath);
NSDictionary *dict;
if (0<) {
dict = ;
}
</code></pre>
<p>此时，文档中的元素应该在 <code>dict</code> 字典中。</p></p>
