Regex help

[chris86t]

I'm writing a web page parser with VB.NET. I need to use regex to find the info I'm looking for, but have zero regex experience.

I need to find the following lines:

<span class="pricing">$119.99</span>

and

<span class="rebate">$20.00</span>

And just pull out the numbers with the decimal (119.99 or 20.00)

Right now I'm using this regex code:

"pricing"">*(?:""(?<1>[^""]*)""|(?<1>\S+))"

And it returns:

$119.99</span>

When i want it to return just 119.99

The page I'm pulling from is

Are you saying you want to write to registry?

With pattern Like this.
[tt] 'Dim pattern As String
pattern="(?<=<span\s+[^>]*?class\s*=\s*\k<q>\s*(pricing|rebat)\s*(?<q>(""|'))[^>]*?>\s*\$)([^<]*?)(?=\s*</span>)"[/tt]

<span class="rebate">$20.00</span>

No such line exists in the source (at least, not in the example source you ahve provided).

f course, we could just parse the DOM ...

Well, after browsing

http://regexlib.com

and not finding a solution, I followed some liks from that page and came up with this. It works ok for now.

"[pricing|rebate]"">\$*(?:""(?<1>[^""]*)""|(?<1>[0-9|\.|\,]+))"

Regex is confusing at first, but then starts to make sense after a bit of reading
