1.使用 tfhpple 

  1.1.导入TFHpple

  1.2.引入静态库文件libxml2.2.tbd 不是 libxml2.dylib ,ios9 xcode7不使用了

2. 使用 xpath 获取数据 节点

 //*[@id="index_main"]/div/div/h3/a

F12    输入 $x("//*[@id='index_main']/div/div/h3/a") 

userName	//*[@id='index_main']/div[2]/div/div[3]/a/text()
 userPicLink    //*[@id='index_main']/div[2]/div/div[1]/div/a/img/    src
 userBlogLink   //*[@id='index_main']/div[2]/div/div[3]/a             href
 title          //*[@id='index_main']/div[2]/div/h3/a/text()
 content        //*[@id='index_main']/div[2]/div/div[1]/text()[2] 
 articleLink    //*[@id='index_main']/div[2]/div/h3/a                 href
 seeNum         //*[@id='index_main']/div[2]/div/div[3]/span[2]/text()
 goodNum        //*[@id='index_main']/div[2]/div/div[3]/div/div/a[1]/text()
 badNum         //*[@id='index_main']/div[2]/div/div[3]/div/div/a[2]/text()
 insertTime     //*[@id='index_main']/div[2]/div/div[3]/span[3]/text()
 type
 html

3. 代码部分
