World Bank Data API: Converting links to data?

Hello,

The World Bank website currently allows anyone to use it's worldwide data

In the above page, the World bank provides a basic call structure format. Following this protocol, I have generated links such as:
Surface area (sq. km) of Ethiopia: http://api.worldbank.org/countries/ETH/indicators/AG.SRF.TOTL.K2?MRV=1&Gapfill=Y

Entering the above link into a url, returns the following data:

<wb:data xmlns:wb="http://www.worldbank.org" page="1" pages="1" per_page="50" total="1">
<wb:data>
<wb:indicator id="AG.SRF.TOTL.K2">Surface area (sq. km)</wb:indicator>
<wb:country id="ET">Ethiopia</wb:country>
<wb:date>2014</wb:date>
<wb:value>1104300</wb:value>
<wb:decimal>0</wb:decimal>
</wb:data>
</wb:data>

Select all Open in new window

I'm not a programmer, but all I want to be able to do is grab the <wb:value> of 1104300 above and add it to a webpage, for multiple url links.

E.g my website would have 10 separate pages (one for each country) and on each of these pages would be the label: Surface area (sq. km): alongside the pulled World Bank data from the above url.

How would I approach this?
