【推荐】oc解析HTML数据的类库（爬取网页数据）

　　TFhpple是一个用于解析html数据的第三方库，本人感觉功能还算可以，只不过在使用前必须配置项目。

　　

　　配置

1.导入libxml2.tbd

 

2.设置编译路径

 　　使用

这里使用一个例子来说明

http://so.gushiwen.org/guwen/book_2.aspx

 

 1.创建TFHpple对象，data为网站返回的数据

TFHpple *htmlParser = [[TFHpple alloc] initWithHTMLData:data];

 

 2.使用searchWithXPathQuery方法得到有用数据，XPATH知识具体百度

NSArray *temp1 = [htmlParser searchWithXPathQuery:@"//div[@class='shileft']/div[@class='bookcont']"]

这样我们获取了论语的数据

 

3。获取并分析元素

TFHppleElement *element = [elements objectAtIndex:i];

 TFHppleElement对象包含许多属性，下面简单介绍一下各属性

1。

@property (nonatomic, copy, readonly) NSString *raw

 raw是包含html标记的网页数据

<div class="bookcont">&#13;
