[REBOL] Parsing until the end
From: fuka::fuxoft::cz at: 5-Jan-2003 21:21
Let's say I have string like this:
XYhelloXYpeopleXYXYhowXYareXYyouXY
XY
acts as sort of separator. Now, I want to extract the string that
follows "XYXY" and ends right before the last XY. If there's no "XY" at
the end, don't extract anything.
So, the result of:
my-magic-split "XYhelloXYpeopleXYXYhowXYareXYyouXY" "XY"
should be: "howXYareXYyou" ;notice there's no "XY" at the end.
I thought that this could be somehow done using "end" in the parse rules
but I couldn't come up with anything that would work like i intend. I
had to extract everything after "XYXY" and then removing the last 2
characters if they are equal to "XY" and clear the whole string if they
are not. But this doesn't seem very elegant to me.
