Hi,
Wouter is right:
It is indeed elegant, but a condition check is necessary here as it
will remove the first word + the space(s) if there is no space at the
start of the line.
" The cat sat on the mat. "
But if no space in front the result is
"cat sat on the mat. "
This is actually true -- and a serious bug in Revolution's RegExp
engine.
The Regular Expression Syntax reference states:
^ matches the following character at the beginning of the string
^A matches "ABC" but not "CAB"
* matches zero or more occurrences of the preceding character or
pattern
I assumed that Revolution would do what it promised and didn't
check this.
Try
answer replaceText("A C","^ *","")
I get "C", which obviously is not correct.
If I remove the "*", I get "A C"
This may be a bug. (I'm not sure.)
But the following will work:
answer replaceText("A C","^ +","")
I.e. match "at least one" occurrence of a space, which is what is
intended.
Cheers
Dave
