Help with regex expression for words in all caps

[bfollowell]

I am attempting to create a regex expression that will allow me to search for "words" made up of consecutive upper case characters such as DANGER or WARNING. I tried [A-Z]+ and it does not work.

[A-Z] returns any and every occurence of an upper case character, single or multiple, one at a time.
[A-Z]+ returns groups of upper case characters as well as single upper case letters

I can't seem to find an expression that will return only groups of consecutive upper case characters. I don't care about the singles at the beginning of a sentence or a proper name.

I know Sigil regex has some quirks that work differently than in other apps that use regex. Does anyone have any ideas?

([A-Z]){3,}

the first number is a minimum repetition count
the Second is a maximum. infinite if nil after the comma

Just a guess, but have you tried:

[A-Z][A-Z]+

instead?

Both of these seem to work as I wanted. The second one works best for any number of multiple characters. The first one works better if I only want to look for words x number of characters or longer. I'll make certain to save both of these in my really, really, big book of commonly used regex expressions. Thanks guys.

If you're using one of the beta versions, and you want to get upper case words, a better option would be something like : \b[[:upper:]]{2,}\b

I'd be very careful with that one, especially if you want to use the replace function.
Much better:
([A-Z]{3,})

Else you will just replace ONE letter with \1...

The suggestion from Serpentine will "only" find complete words that are uppercase, that might be what you want or not, I can't decide...

I know, in the past, the posix classes never seemed to work. Is that one of the new additions from the beta versions? I was using beta 0.4.0 and I'm pretty sure they didn't work then. I'll be glad to see them though.

Thanks again to everyone for all of the help.

That is why it happened

Yup, you have pretty much all of the PCRE library to play with now.

Covers pretty much everything, not exactly nice reading, but if you jump around a bit you'll find lists of all of the nifty stuff, some nice examples.

in 4.2, how would I replace uppercase between a span to lowercase?

For example,

<span class="small">THIS IS UPPERCASE</SPAN>

There could be multiple instances on the same line. This is so I can easily fix the fake smallcaps to true smallcaps easily.
