Hi PravinD -


Cool, OK, let's see:

Hm. The XPath rule below will catch field declarations of Strings that don't start with "str":


//FieldDeclaration
[
Type/Name[@Image='String']
and not(starts-with(VariableDeclarator/VariableDeclaratorId/@Image, 'str'))
]


and you can write similar ones for parameters and local variable declarations.

Check out the CloseConnection rule here:
