Question

ticket number: 6666
ticket number : 6666
ticket #6666
ticket # 6666

i tried this one ticket[ \\t]+(number|#)?[: \\t]+([0-9]+) but it does not work for "ticket #6666"

Could anybody help?

Answer 1

Close; you want the colon/space to be optional.

ticket[ \t]+(number|#)?[: \t]*([0-9]+)

Answer 2

Try something like this: ticket[\\s\\t]+(number|#)[:\\s\\t]*([0-9]+)

Also, if you don't already use it I would recommend http://regexpal.com/ to help you with your testing. It is a great resource to quickly see what is being matched by your expression.
