Regular Expression Logic problem

[karlectomy]

Hey all,

I have a parsing application where I am taking text files and choppiing them up (so to speak) There are small formatting differences which I was hoping to take care of with regular expression logic.

Here is example of one line:

$CHAP_01.txt$ 1 Chapter One

This line should be equivalent:

$CHAP_01.txt$ 1. Chapter One

(See the period after the one?)

I am using the split function with the regular expression " \\d+ " which works fine for the first one but for the second, I get an out of bounds exception when I refer to index 1 in the output array.

I was wondering if there was some way to use " \\d+ [ \\d+\\. ]" or some other logic in the regular expressions to split those two line s the same..

THanks

You want a literal dot at the end zero or more times; regular expressions can
easily take care of that: \.?

That is: a literal dot (escaped) with a closure ? (zero or one times). Of course
you have to use two backslashes it you want to put that regular expression in
a literal string: \\.?

kind regards,

Thanks Jos,

That works! but I also figured it out on my own using " \\d+(\\. | )" which is a dot followed by a space or just a space.

Yep, you're welcome of course; when you use regular expressions there are more
ways that lead to Rome ;-)

That's very true and also, com.cities.rome wasn't built in a day :)

True; and don't forget: when in Rome do as the Romans do.
