DB tool's result is returning in string, So unable to do assertion or keeping in XML data bank.
Please let me know how to convert to xml and assert .
I'm not sure what you are referring to. From the docs:
"This tool sends an inquiry to the database you specify, and the results from the query will be returned. SOAtest and/or Virtualize formats the results into XML; this allows XML based tools (XML Data Bank, XSLT Tool, etc.) to be chained to the output."
