I need to find first 开发者_StackOverflow社区& last line using Regex on Notepad++

How can I find first and last line ?

---

Not sure if this works, but I used this in Textmate:

^(?:(?<![\f\n\r])(?:.*))(?=[\f\n\r])|^.*(?![\f\n\r])$

The first part,

^(?:(?<![\f\n\r])(?:.*))(?=[\f\n\r])

finds the first line. Not sure about Notepad++, but (annoyingly) Textmate matches ^ to any start of line. So I had to check for the text (.*) that is followed by a form feed, newline or return ([\f\n\r]), and is not preceded by the same.

The second part,

^.*(?![\f\n\r])$

was easier. It just finds a start of a line (^) with the text (.*) that is not followed by a end of line.

EDIT: after re-reading OP's post I get that it should have the beginning tag and closing tag. To do that, you could use the first part of the expression for the beginning tag and the last expression for the end tag.
