Connecting to API Using ASP
Included here you will find simple sample code for parsing the Database Interface API in XML.
The first example returns primary data for a given jurisdiction - the result containing the
United States Post Office. Some ZIP codes include multiple cities and sometimes multiple tax jurisdictions,
so the second example shows how to go down the hierarchy and parse the XML.
