Regular Expressions in VB.NET 2005 ?

[Cojba]

'Define regex
Dim regExp As RegularExpressions.Regex

'Italic text
regExp = New RegularExpressions.Regex("<i>$1</i>")
RichTextBox2.Text = regExp.Replace(RichTextBox1.Text, "\[i\](.+?)\[\/i\]")

Input should be: <i>blahblah</i> and output blahblah, but it gives me same text from richtextbox1 in richtextbox2. Anyone can see whats wrong in this code ?

you shoud never ever use regex to parse html. the best and fastest way to parse strings is using IndexOf. There is a HTML agility pack that allows you to use xPath.
