Asp.net - HTML Agility Pack Removes Break Tag Close?

Apr 5, 2011

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)

Remove Specific Elements From HTML With Agility Pack For Program?

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)

Select A Specific Table Cell Using HTML Agility Pack

Jan 18, 2012

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]

Stripping HTML Function Within Text Areas Content

Mar 10, 2010

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?

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

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?

Sending An HTML Email, Where The HTML Comes From An HTML File .Net/ClickOnce Environment?

Jun 20, 2009

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. The users understand to use absolute link and image references when sending an E Newsletter. Environment:

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).

Using HTML Tags To Become Bold In Preview?

Apr 19, 2011

After starting a new project for easy "Templates" I am wondering on how I can preview the template.

Here's my situation. I have a form with 2 richtextboxes. One for editing, one for previewing. This application is basically for HTML. For example, bold in HTML is <strong></strong>. If the user types the tags with text in between these tags, I want them to be able to preview this text in bold (assuming the tags are <strong></strong>.)

I'm not sure how I can preview it. Lets say the user types this phrase in the RichTextBox1:

<strong>Hi World!</strong>

I want the preview to show Hi World! because I put bold tags around the phrase "Hi World!". The reason why I need the textbox to use tags is because this application's purpose is to simplify work with HTML by allowing the user to "see" and preview what they are writing.

Here is what I have to insert text by click of a button. (Works perfectly)

Private Sub InsertBold(ByVal selection As String)
RichTextBox1.SelectedText = selection
End Sub

Strip All HTML Contents Except Anchor Tags

I'm importing data from 1 database to another. I've been requested to strip all HTML content, as its messy and not valid, and just keep the links. I currently use the following VB.NET function to strip all HTML tags from a string of content:

Public Shared Function StripHTML(ByVal htmlString As String) As String
Dim pattern As String = "<(.|
)*?>"
Return Regex.Replace(htmlString, pattern, String.Empty)
End Function

I'm looking for a way of stripping all, but a (anchor) tags from the content. For example if I have the following HTML content:
<table><tr><td>
Lorem <a href="[URL]">Ipsum</a>
</td></tr></table>

Lorem <a href="[URL]">Ipsum</a>
