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"> <ul> <span><a href="/guwen/bookv_19.aspx">学而篇</a></span> <span><a href="/guwen/bookv_20.aspx">为政篇</a></span> <span><a href="/guwen/bookv_21.aspx">八佾篇</a></span> <span><a href="/guwen/bookv_22.aspx">里仁篇</a></span> <span><a href="/guwen/bookv_23.aspx">公冶长篇</a></span> <span><a href="/guwen/bookv_24.aspx">雍也篇</a></span> <span><a href="/guwen/bookv_25.aspx">述而篇</a></span> <span><a href="/guwen/bookv_26.aspx">泰伯篇</a></span> <span><a href="/guwen/bookv_27.aspx">子罕篇</a></span> <span><a href="/guwen/bookv_28.aspx">乡党篇</a></span> <span><a href="/guwen/bookv_29.aspx">先进篇</a></span> <span><a href="/guwen/bookv_30.aspx">颜渊篇</a></span> <span><a href="/guwen/bookv_31.aspx">子路篇</a></span> <span><a href="/guwen/bookv_32.aspx">宪问篇</a></span> <span><a href="/guwen/bookv_33.aspx">卫灵公篇</a></span> <span><a href="/guwen/bookv_34.aspx">季氏篇</a></span> <span><a href="/guwen/bookv_35.aspx">阳货篇</a></span> <span><a href="/guwen/bookv_36.aspx">微子篇</a></span> <span><a href="/guwen/bookv_37.aspx">子张篇</a></span> <span><a href="/guwen/bookv_38.aspx">尧曰篇</a></span> </ul> </div>
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。
