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

 
 
 学而篇
 
 为政篇
 
 八佾篇
 
 里仁篇
 
 公冶长篇
 
 雍也篇
 
 述而篇
 
 泰伯篇
 
 子罕篇
 
 乡党篇
 
 先进篇
 
 颜渊篇
 
 子路篇
 
 宪问篇
 
 卫灵公篇
 
 季氏篇
 
 阳货篇
 
 微子篇
 
 子张篇
 
 尧曰篇
 
 
 

2.content是网页的具体数据，不包含html标记

学而篇 为政篇 八佾篇 里仁篇 公冶长篇 雍也篇 述而篇 泰伯篇 子罕篇 乡党篇 先进篇 颜渊篇 子路篇 宪问篇 卫灵公篇 季氏篇 阳货篇 微子篇 子张篇 尧曰篇

3.tagName是html标签

输出只有div

4.attributes，属性。。。。

class = bookcont;

5.children子节点

上面属性都是涉及HTML语言的标记，我们一般使用的时content属性，然后处理得到的NSString对象

这样我们就得到并处理为我们想要的数据。TFHppleElement是一个很重要的类，具体使用在这里就不介绍了。
