DIV that contain a string

[tc2k11]

Can I block a DIV that contains a certain string within its tags?

For example google.com##DIV.textBody[this is the string I want to identify]

...so that for every DIV class=textBody that contains the string "this is the string I want to identify" it blocks the entire DIV?

The answer is no, I guess. Could you guys implement this functionality? that would help a lot.
