[REBOL] parsing text???? Re:
From: jelinem1:nationwide at: 25-Aug-2000 8:53
First, unless you know something I don't (very possible) I don't think the
following is correct:
copy url to {?|"|newline}
This will look for the string '?|"|newline' in the file. I think what you
really wanted was:
copy url [ to "?"| to {"}| to newline]
Unfortunately this won't work and is my biggest pet peeve with 'parse. What
*I* expect this to do is to look for the first occurrance of "?" OR {"} OR
newline, WHICHEVER COMES FIRST. What this actually does is to look for an
occurrance of "?" in the file. If the ENTIRE FILE does not contain "?" then
it looks for an {"}. Again, if the ENTIRE FILE does not contain {"} then it
looks for newline. Is this bevavior useful in anybody's case? I guess it
could be, but I haven't run into it yet.
If your data does not contain "?" or {"} then you can use your code but
you'll have to process a line at a time. Instead of searching the entire
file for one of these chars, it will only search the entire current line.
Either that, or rewrite your code NOT to use 'parse. NOTE: You might be
able to do something with 'charset but I haven't played with enough to know
for sure.
