Using math in browser using XML data

I'm trying to make pull XML or Csv data into a HTML file then I want to use math to add up the values and show the result on the page ( I'm basically trying to display invoices on a web browser)My skill set is HTML/CSS and I understand a little JavaScriptI've managed to pull XML data into HTML using http request and style that information using xslt Really what I'm asking is what is the best solution to my needs is it using the above method then using xquiry to add up values or would I need to learn a bit of Ajax, Json and calculate the values with JavaScript?
