Need to extract text messages out of an HTML document

问题

Hello, I have a long HTML document, this is only the part that interests me:

It outputs as follows:

You're now chatting with a random stranger. Say hi!

Stranger: hii thereStranger: nice to meet youStranger: this is a textYou: this text should not be takenStranger has disconnected.

I want to extract all messages sent by Stranger into strings (Visual Basic), and ignore messages sent by me and system messages such as You are now chatting with a random stranger. Sai hi! and Stranger has disconnected. I have no idea on how I should approach this and need help, thank you.

If anyone else is interested in such an operation, I've managed to simplify the process by applying the HTML code to another webbrowser then using the Document.Body.InnerHtml property to get the text output in a richtextbox, so I can easily deal with the text instead of dealing with the HTML code.

OmegleHTML.Text = Omegle.Document.Body.InnerHtml
WebBrowser1.Document.Body.InnerHtml = OmegleHTML.Text
Log.Text = WebBrowser1.Document.Body.OuterText

I've also used the following code to get rid of any irrelevant text before the chat log:

Dim SInd, Eind As Integer
SInd = 0
Eind = Log.Text.IndexOf("You're now chatting with a random stranger. Say hi!")
Log.Text = Log.Text.Remove(SInd, Eind)

This is the closest I've got. If you have a better answer, please post it.
