perl program to delete the complete record

Hi all,

I want a perl program to delete the record and its contents from a file if there is no particular line in the record given that all records are separated by a blank line.

For example:
Code:
#100
abcd
efgh
hijk
123
klm

#200
abcd
efgh
hijk
klm

So, the pattern here is 123. If there is no line 123, I want to delete the complete record. #200 does not have line 123 so I want to get rid of that record from #200 till klm. This process is to continue until end of the file.

Thanks in advance.
