Hi James... I tried:
matchText( z, "^[A-Z]") and it worked fine for me... I tested it in the message box... matchText("b","^[A-Z]") returned false, and matchText("B","^[A-Z]") returned true -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, December 09, 2004 3:47 PM To: How to use Revolution Subject: Re: testing on case > The expression matchText( z, "^[A-Z]") > will return true if (and only when) the > first character is an ASCII capital letter. That returns "false" for me. You'll need to do it like this to cover upper and lower case. matchText(z,"^[aA-zZ]") Cheers...James |---------+---------------------------------------> | | Dar Scott <[EMAIL PROTECTED]> | | | Sent by: | | | [EMAIL PROTECTED]| | | .runrev.com | | | | | | | | | 12/09/04 02:53 PM | | | Please respond to How to use| | | Revolution | |---------+---------------------------------------> >----------------------------------------------------------------------- ---------------------------------| | | | To: How to use Revolution <[EMAIL PROTECTED]> | | cc: | | Subject: Re: testing on case | >----------------------------------------------------------------------- ---------------------------------| On Dec 9, 2004, at 11:46 AM, Hershel Fisch wrote: >> if matchText( param(x), "^[A-Z]") then put xxx else put x > I don't get it The expression matchText( z, "^[A-Z]") will return true if (and only when) the first character is an ASCII capital letter. The "^" matches the beginning of the string (or line). A more exact pattern is "\A"; I used "^" because it might be more familiar. The immediately following pattern [A-Z] matches any letter in the range A-Z in ASCII. It must match right after the previous pattern match, that is, the beginning. There is no pattern matching for the end of the string so the rest of the string z does not matter. That is, matchText() returns true if the pattern occurs anywhere in the string, not just if it matches the whole string. (Use \A and \z to match the ends to make a pattern match the whole string.) You can find more info on regular expressions here: http://www.perldoc.com/perl5.8.0/pod/perlre.html But you have to skip over all the perl specific parts. You can find more specific information on exact usage of the actual library used in Revolution and (I assume) Dreamcard here: http://www.pcre.org/pcre.txt But you have to skip over all the building and calling parts. Skip down to PCRE REGULAR EXPRESSION DETAILS. I think you need to skip over the unicode and UTF-8 paragraphs, too, for now.
