HtmlAgilityPack基本如何获得标题和链接？ [英] HtmlAgilityPack basic how to get title and link?

问题描述

Html

 < div class =col> 
< a class =video-boxtitle =En son haberhref =http：// ** / en-son-haber> 
 < span class =title>儿子haber< / span> 
< span class =duration> 01：02< / span>< span class =view-count> 9.023< / span>< / a> 
< / div> 
  

代码

  Dim request2 As HttpWebRequest = WebRequest.Create（http：//**.com/）
 Dim response2 As HttpWebResponse = request2.GetResponse（）
 Dim reader2 As StreamReader = New StreamReader（response2.GetResponseStream（））
 Dim sayfa2 As String = reader2.ReadToEnd（）
 Dim dokuman2 = New HtmlAgilityPack.HtmlDocument（）
 dokuman2.LoadHtml（sayfa2 ）
 
 Dim getir2 As HtmlAgilityPack.HtmlNodeCollection =dokuman2.DocumentNode.SelectNodes（// div [@ class ='col']）
对于每个节点在getir2 
 TextBox1 .Text + = node.SelectSingleNode（// a [@ class ='video-box']）。SelectSingleNode（href）。InnerText 
 Next 
  

我想要获得 link 和 title in一个 div 但 SelectSingleNode 检索重复值..

如何得到真实。 示例rel =nofollow> http://htmlagilitypack.codeplex.com/wikipage?title=示例，第一个示例显示如何访问属性。

所以在你的情况下

 对于每个节点在getir2 
 dim aTag中，为HtmlAgilityPack.HtmlNode = node。 SelectSingleNode（// a [@ class ='video-box']）
 TextBox1.Text + = aTag [href]。value 
'，标题为
 TextBox1。 Text + = aTag [title]。value 
 Next 
  

Html

<div class="col">                   
<a class="video-box" title="En son haber" href="http://**/en-son-haber">
<img class="img-responsive" alt="en son haber" src="http://**/thumb/6/9/6/200x120/en-son-haber-49-29.jpg"> 
<span class="title">En son haber</span>
<span class="duration">01:02</span><span class="view-count">9.023</span></a>
</div>

Code

 Dim request2 As HttpWebRequest = WebRequest.Create("http://**.com/")
 Dim response2 As HttpWebResponse = request2.GetResponse()
 Dim reader2 As StreamReader = New StreamReader(response2.GetResponseStream())
 Dim sayfa2 As String = reader2.ReadToEnd()
 Dim dokuman2 = New HtmlAgilityPack.HtmlDocument()                         
 dokuman2.LoadHtml(sayfa2)

 Dim getir2 As HtmlAgilityPack.HtmlNodeCollection = dokuman2.DocumentNode.SelectNodes("//div[@class='col']")
 For Each node In getir2             
      TextBox1.Text += node.SelectSingleNode("//a[@class='video-box']").SelectSingleNode("href").InnerText 
 Next

I want get link and title in a div but SelectSingleNode retrieving duplicate value..

How to get true.

解决方案

If you see the examples page http://htmlagilitypack.codeplex.com/wikipage?title=Examples, the very first example shows how to access attributes..

so in your case

 For Each node In getir2   
      dim aTag as HtmlAgilityPack.HtmlNode = node.SelectSingleNode("//a[@class='video-box']")
      TextBox1.Text += aTag["href"].value
      'and for the title
      TextBox1.Text += aTag["title"].value
 Next
