Opensips with DB_text module and avpops module config

Using OpenSIPS I need to get some data from a text file (db_text) and reference that data using an AVP variable (avpops). I just need a working example. For instance, my text file contains below and I need to extract the attribute with the value associated in the request route. If you can do this, it should be straight forward. I'll provide access to my server in the cloud. Sample File id(int,auto) username(str) attribute(str) value(str) 1:1234:site1:9545551212 2:i5678:site2:7183334444
