case conversion in regexp subexpression

Jens Romm #1 / 7	case conversion in regexp subexpression Hi all, i searched a lot but didn't find any hint how to solve the following issue: I'm looking for a regular expression that produces a subexpression with the first character uppercase no matter the case was in die matched sample. E.g. getCustomer --regexp--> Customer getcustomer --regexp--> Customer getxyz --regexp--> Xyz What i have found so far is the simple get(.*) but that doesn't uppercase the first character. I'm using gnu.regexp regular expressions for java so i cannot deal with perl operations. Any help would be greatly appreciated. Thanks

Despite your cross-post, your inquiry is not strictly on-topic in any of the newsgroups. Parenthetically, congratulations on breaking new conceptual ground and thinking something would be on-topic in both Perl and Java newsgroups at the same time. http://www.google.com/search?hl=en&q=regexp+tutorial -- Paul Lutus www.arachnoid.com

Is there any reason not to do the uppercase transformation as a String or StringBuffer operation after the regular expression has done the extraction? Note that Character has a static toUpperCase method.

Huh? The inquiry is about the use of a "regular expressions for java" package. That seems like a matter of Java programming and a request for help with Java. Given the stated inability to use Perl, I'm changing the follow-ups to delete comp.lang.perl.misc Patricia

Anyway this it exactly what i could have expected posting this question to perl.misc: I am not able to use s/// so i am not able to modify the $1 value _after_ its evaluation. I need need $1 to equal "Customer" directly. Is this possible?

I didn't read your OP carefully enough. Had I done so I would have ignored it since it's obviously off-topic here. Cheers, Bernard

Perl has the ucfirst() and lcase() builtin functions, but you can't use that in Java. No you can't do it with a regex alone, since what it matched is literally what it matched. -- Bart.
