How to parse certain text in the webbrowser?

What I'm trying to do is parse certain text from a webpage that is loaded into the webbrowser. To be more specific, this line of code.

Code:

$20.00

It sits on line 1342. If it helps, this is all the code before it, that sits on the same line.

Code:

<input type="image" onclick="return onAddToCartClick('selecttrainform', '1', '');" src="/images/en/avs_addtocart_gray.gif" alt="Add To cart >" border="0" name="_handler=presentation.handler.request.rail.RailSimpleSelectDepartAvailabilityRequestHandler/_xpath=/sessionWorkflow/productWorkflow[@product='Rail']/tripJourneyTariffAvailability/journeyTariffAvailability[1]/binding[1]/journey/segment[1]/_/sessionWorkflow/productWorkflow[@product='Rail']/selectedJourney/@id_=_hy0s6wf8a3gi" />$20.00

What I'm trying to do with that price is have a message box display it. I can either have three different msgbox come up, drawing from three different webbrowsers, or just one msgbox that shows from all three. It's not a big deal to me. As well, this code will just be placed in a button. Of course, if need be, I can have the information display in a textbox rather than a msgbox. I just much prefer a msgbox.

I was thinking I could use something like

Code:

If webpageelement3.GetAttribute("id") = "selecttrainform1_addToCartPrice" Then MsgBox("the price data here")

but I'm not sure how that'd work to get it to display into the messagebox. The above code is part of what I used to find and click a button, just left out the webpagelement.invokemember("click") command.

Does anyone know of any resources or links that would be helpful? I've tried searching through google but it's been fruitless for the moment.

I've already tried many of the posts on this forum but none of them seem to help.
