Hello, I've got the following problem: Suppose you have the strings
contains:
"xxxx aaa { 111, 222, 333} bbb {111, 222,333} yyyy"
"xxxx aaa {1112, 2223, 3334} bbb {11112, 22223,33334,444 45} yyyy"
I need to select only those strings which match the sequence aaa {...}
with number 222 inside brackets. Number 222 can be of course at any
position inside brackets e.g. aaa {222, 333, 111}, or aaa
{111,333,222}.
How to do this with REGEXP ? Something like this:
1. find aaa
2. skip zero or more white chars until '{'
3. find sequence: "222 , ... }" or " ..., 222 , ...}" or "..., 222 }"
thanks for the help.

I don't think so. It finds also aaa {111, 2222, 333} and 2222 != 222 :-(

OK. Maybe the beginning and end of word markers might help
..*aaa {.*[[:<:]]222[[:>:]].*}.*
Also, I don't think we need the leading and trailing .*, as that's
automatic, so
aaa {.*[[:<:]]222[[:>:]].*}
Now is { or } a special character too?

don't work at all :-( the expression also finds
"aaa {111, 333, 444} bbb {111,222,333}" because .* at the end skips
any number of chars which is always true, but i need to limit search
only between {} brackets. i can of course replace {} chars with
anything else, e.g. quotes, or double quotes, or () brackets, but the
search must be always limited between those chars. thanks once again

Oops, I thought that's what you wanted as the 222 is within brackets. But
it has to be between the brackets right after the aaa. If so I think you
should replace any numbers of characters .* with any number of characters
that are not braces.
aaa {[^}]*[[:<:]]222[[:>:]][^{]*}
This means aaa, followed by space, followed by {, followed by any number of
chars that are not the close brace }, followed by 222 as a single word, etc.
The one thing to wonder about is what is the definition of a word.
