I have a html text file and I am trying to remove any HTML tags in tables, i.e. remove any HTML within THE <TABLE> and </TABLE> tags.
However, what's really weird is that the regex that I use, (?<=<table((?!</table).)*)<(?!/table)[^>]+>, works perfectly in PowerGREP or EditPad Pro, however, when applied in vb.NET (or Expresso) to the VERY SAME text, it does NOT work! I just use a simple replace method: newString = Regex.Replace(oldString, "(?<=<table((?!</table).)*)<(?!/table)[^>]+>", string.Empty, RegexOptions.IgnoreCase)?
Below is the example text:
texttexetext
<TABLE>
<TAG1>

I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then

Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).

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?

I want to get tags content in a string with regular expression. I wrote it for just one line. When the content changed into some lines from one line, Regex will never do pattern on the tag.

Is there any way in VB.NET to remove all of the whitespaces between tags in HTML? Say, I've got this:
<tr>
<td>
The string I've built is an entire HTML document, and it counts everything before those tags as legitimate space, so I need to trim it out. Is there a reg ex or function out there I could use to do this?

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

This page here has a table I need to parse.
It has multiple tags like this:
<td style="text-align: center;"><img src="http://www.pkmdb.com/res/icons/001.png" alt="Pokemon" /></td>
<td style="text-align: center;">001</td> <td style="text-align: center;"><a href="http://www.pkmdb.com/DL/PKM/bulbasaur.pkm">Bulbasaur</a></td> <td style="text-align: center;"><img src="http://www.pkmdb.com/res/types/grass.png" alt="Type" /></td>Different Number, different name. I need a way to get the number and name out of these tags. I'm rather terrible at this, and I've seen examples on the site, I just don't know where to start really on this.
