Reg Ex samples

I've been reading up on Reg Ex and just STARTING to get my head around the subject. One use I've found for it immediately is with Dreamweaver. (Dreamweaver has a "regular expression" search option). Just for my own future re-use and storage – I'll post a few I've used. (Will probably/hopefully add to this post over time…)

searches for

<[/]*tr>
searches for
and

To replace only PORTIONS of what you find -
search for:

and then you can replace lit like this

(will "save" anything it found with (.+) and keep it in the replace with $1

Used this one today (6/5/09) – had to find spaces in a query string and replace it with %20
(pagename.php[?]m=\S[^"]*)[\s]
That will find pagename.php?m=anything except the ending quote
It stores everything except the space (should be the last one in the query string) in $1 so you can do a replace with:
$1%20

New one (8/14):

That will find all the comments on the page (again this is in dreamweaver)

Updated 7/26:
\?\>\s$$
Finds a file with space after ?> at the end of the file.
