creating soap requests via command line

Using the command line mechanisms, is there a way to send soap requests with specific values for the attributes and get soap responses back in the output of the command run?

I am very new to soapui and not sure how granular the command line usage can be.

I have a lot of test code that is written in TCL which is a scripting language. I understand soapui uses groovy, and i am wondering if others use different scripting languages and built any kind of wrapper around the command line usage for their specific scripting languages.

Please advise. Thanks.
