Somewhat related to this question, but in the absence of any answer about QuickBooks specifically, does anyone know of an address parser for Java? Something that can take unstructured address information and parse out the address line 1, 2 and city state postal code and country?

I do know that the Google Maps web service is great at doing this. So, if you want to use that, you could save a lot of effort.

The real issue here is that you need a worldwide database of city/country/province names to effectively parse UNSTRUCTURED addresses.

Here is how I build a URL for use by the Google Maps API in C#:

string url = "http://maps.google.com/maps/geo?key=" + HttpUtility.UrlEncode(this.apiKey) + "&sensor=false&output=xml&oe=utf8&q=" + HttpUtility.UrlEncode(location);
