    【解决方案1】:
    【解决方案2】:

    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 项目的构建设置并设置以下内容:

    • Other linker flags = -lxml2
    • Header Search Paths: $(SDKROOT)/usr/include/libxml2

    然后从这个页面下载 XPathQuery.m 和 XPathQuery.h:Using libxml2 for XML parsing and XPath queries in Cocoa,其中还提供了如何使用它的教程。 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。

    有了这个,就去做

    NSString *string = nil; // put your html document here
    
    NSData *htmlData = [string dataUsingEncoding:NSUTF8StringEncoding];
    NSString *xpath = @"//row"; // any standard XPath expression
    NSArray *nodesArray = PerformHTMLXPathQuery(htmlData, xpath);
    NSDictionary *dict;
    if (0<[nodesArray count]) {
        dict = [nodesArray objectAtIndex:0];
    }
    

    此时,您文档中的元素应该在 dict 字典中。
