Need 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.
Dim htmldoc As HtmlDocument = New HtmlDocument
htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")
[code]....
I have tried this:
Return htmldoc.DocumentNode.InnerText
But still no luck!
I've given a job to convert old data in table format to new format.Old dummy data is as follows:

Dim node As HtmlNode
Dim nuovo As HtmlNode

There's plenty of examples out there for other languages. Are there any examples for vb.net?

View 1 RepliesI 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]

I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?
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>
[Code]...
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?
Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question.

AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).

i'm trying to get the following data from within the html tages <td class="colRight">CWCH60</td> where CWCH60 is the data which changes and needs to be extracted. I have tried the following Regex patterns
[^td|<|>|/|class|s|^="colRight"][A-Z|a-z|0-9][^</td>]
[^<td][^s][^class][^="colRight">][A-Z|a-z|0-9][^</td>]
[^tdsclass=""colRight">][A-Z][a-z][0-9]
all work fine in an online regex builder/tester but return WCH60 when executed. Why would this occur, is there a simple operator i have missed out?
