emacs regexp question

[gmayer]

Hello:

There are some regexps I don't know how to specify in gnu emacs:

- How should I ask for the first occurrence of two blank lines?

- How should I ask for the first occurrence of N blank lines for some fixed,
yet large, N. I think emacs uses ^ for the start of the line, though I've
seen some regexp libraries (not for emacs) that use the ^ as a sort of
"exponentiation" symbol for the number of times a string is concatenated.

- How can I search for regexps that have one or more newlines in the middle?

Brief explanations and/or brief examples of the above would greatly be
appreciated!

Thanks,

Mayer (gmayer@cs.bgu.ac.il)
