From:		PravinD
I am attempting to create a couple of PMD rules. 1) To create a rule that checks for the occurences of String objects and throws a warning if the names of the objects do not start with the letters 'str' 2) To create a rule that checks for open connection objects and throws a warning if these objects remain unclosed. Can someone help me on this or post the xpath rule for the same?

  Hi PravinD -
  
  Cool, OK, let's see:

  > warning if the names of the objects do not
  > start with the letters 'str'
  
  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:

  Hi Pravin -
  
  Sounds good! But you may want to post questions on the PMD forums:
  
  http://sourceforge.net/forum/forum.php?forum_id=188192
  
  A bunch of people monitor those forums, and you may get a faster answer that way...
  
  Yours,
