Question
I honestly don't know how to do this, and I am very stuck. My code is probably not worth sharing, but I will try my best to ask the question.
<div class="pricing-table">
<div class="span4">
<div class="plan">
<h3>PPTP <span>$0</span></h3>
<ul>
<li><b>IP:</b> " (hidden)"</li>
<li><b>Username:</b> " Guest"</li>
<li><b>Password:</b> " (hidden)"</li>
<li><b>Unlimited</b> " Bandwidth"</li>
<li><b>Torrents</b> " Allowed"</li>
<li><b>No</b> " Logging"</li>
</ul>
</div>
</div>
</div>
(This is the second one)
<div class="span4">
<div class="plan most-popular">
<h3>Open<span>$0</span></h3>
<div class="plan-ribbon-wrapper">
<div class="plan-ribbon">
Popular
</div>
</div>
<ul>
<li><b>Username:</b> user</li>
<li><b>Password:</b> (hidden)</li>
<li><b>TCP</b> 80, 443</li>
<li><b>UDP</b> 53, 40000</li>
<li><b>Unlimited</b> Bandwidth</li>
<li><b>Torrents</b> Allowed</li>
<li><b>No</b> Logging</li>
</ul><a class="btn btn-large btn-primary" href=
"%20(hidden)">Download</a>
</div>
</div>
<ul>
<li><b>Username:</b> user</li>
<li><b>Password:</b> (hidden)</li>
<li><b>TCP</b> 80, 443</li>
<li><b>UDP</b> 53, 40000</li>
<li><b>Unlimited</b> Bandwidth</li>
<li><b>Torrents</b> Allowed</li>
<li><b>No</b> Logging</li>
</ul>
Using this HTML code, I want to copy the username and password and put it into a label on my form.
Here is my code
Imports HtmlAgilityPack
Public Class Form1
Dim Prev_Pass, Prev_User, Currt_Pass, Currt_User, Info
Dim counter As Integer
Dim web As New HtmlWeb()
Dim htmldoc As HtmlAgilityPack.HtmlDocument = New HtmlAgilityPack.HtmlDocument
Dim htmlnodes As HtmlAgilityPack.HtmlNodeCollection = Nothing
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
htmldoc = web.Load("website")
htmlnodes = htmldoc.DocumentNode.SelectNodes("//div[@class=""pricing-table""]")
For Each node As HtmlAgilityPack.HtmlNode In htmlnodes
Dim releaseNode = node.SelectSingleNode("//div[@class=""plan most-popular""]")
Info = releaseNode.SelectSingleNode("//ul/li/b[contains(text(), 'Username: ')]").InnerText
Next
Label3.Text = Info
End Sub
End Class
Accepted Answer
Consider the following annotations:
<li>
<b>Username:</b> <!-- Use XPath to obtain this element. -->
" user" <!-- This is the next sibling. -->
</li>
With these annotations in mind:
You can obtain the <b> element using XPath as you have done already and then access the username or password text by means of the NextSibling property like so:
Dim username =
htmldoc.DocumentNode.SelectSingleNode(
"//ul/li/b[text()='Username:']").NextSibling.InnerHtml
Dim password =
htmldoc.DocumentNode.SelectSingleNode(
"//ul/li/b[text()='Password:']").NextSibling.InnerHtml
If you want to access the second occurrence of the element instead of the first, then you you should either use a more specific XPath or use SelectNodes and obtain the element located at the second index by means of an indexer like this:
Dim username =
htmldoc.DocumentNode.SelectNodes(
"//ul/li/b[text()='Username:']")(1).NextSibling.InnerHtml
