I am looking to learn as much about the free source html aglity pack but 99% of what I am running into is code mostly in c sharp. Is VB.NET not the preferred language for html agility pack?
View 2 RepliesNeed a bit of help with HTML Agility Pack!Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.

htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")

I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument()
doc.Load(Server.MapPath("Template.htm"))
Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title")
[code]....
I ended up just reading in my template file as a standard string then loading the html like this
Dim TemplateHTML As String = File.ReadAllText(Server.MapPath("Template.htm"))
TemplateHTML = TemplateHTML.Insert(TemplateHTML.IndexOf("<div id=""topContent"">") + "<div id=""topContent"">".Length, _
html.ToString)
doc.LoadHtml(TemplateHTML)

There seems to be no documentation on the codeplex page and for some reason intellisense doesn't show me available methods or anything at all for htmlagilitypack (for example when I type MyHtmlDocument.DocumentNode. - there is no intellisense to tell me what I can do next)

I have to pull out particular fields from cells in an HTML table. Using Firebug I was able to get the exact XPath to the cells I need (unfortunately, the cells don't have an id tag). I thought I could use DocumentNode.SelectSingleNode and pass in that path, but it doesn't seem to be working right. What am I doing wrong? Or is there a better approach to this than how I am doing it? Unfortunately, I have no experience with XPath so this is turning out harder than I expected it to be. Here's what I have so far (I know the HTML is particuarly messy, but that's not in my control to change):[code]

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
I'm a student taking a beginner computer programming course. My teacher told me to use this website if I have any questions. The lesson I have just studied is about the different types of applications in VB.NET. My assignment asks me to "Give at least five examples of each type of application." I'm supposed to do a web search to find these. The different types of applications I'm supposed to find examples for are: Console, Window, Web, Class Library, Control Library, and Smart Device. Then I'm supposed to provide a description or a screen shot of each example.
I hope my question isn't considered too simple for this forum, but I don't know what else to do! I've spent a long time trying to search for examples myself and I can't seem to find anything.
