Url content into Integer

Hello Folks

I'm working on a new apps that could be usefull in Denmark when shopping online.

I have found in this wonderful community the webservice that i need.

The url could look like this :

http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate?FromCurrency=USD&ToCurrency=DKK

This call will show a number in a webview window, but I need to make som calculations on this figure.

I tried the "convert string to integer" but must be doing something very wrong.

Could someone point me in the right direction or give me an example

Thank you in advance
Mogens
