Getting Data Using an XML API and some data manipulation

I have a database of UK postcodes. I need somebody to use the API at [login to view URL] and return for each postcode the British National Grid Reference Please see the detailed requirements for what is required next. ## Deliverables I have a database of UK postcodes. I need somebody to use the API at [login to view URL] and return for each postcode the British National Grid Reference [login to view URL] British National Grid **Eastings** 146284 **Northings** 529631 So you will then present me with a database showing POSTCODE, EASTINGS, NORTHINGS Then I also have a database of about 340 place names, each with eastings and northings. Unfortunately these are using a different 6 figure grid reference system (the Irish one). What I then need you to do is find the closest match for each place name to a postcode (I also have a database of the postcode's on the Irish Grid Reference system). Then you will be able to produce a British National Grid Reference for each place name on the database. So in the end you will present to me Postcode & Place Names with British Grid References (eastings and northings). You should check the data thoroughly before presenting back to me, as I will check it as well. So I will provide to you a database of place names and postcodes and the irish eastings and northings. For each one you will provide to me the eastings and northings using the british grid reference system. For the postcodes you can use the API, for the place names you need to find the nearest matching postcode and then use those.
