Spliting a string on a second space and not all spaces

[Mike Bates]

I have a series of stings that I want to get values for but there are extra spaces that cause extra gyrations I am hoping someone would be able to help me around.

The string has embedded newlines and returns which I split on first to get to the specific lines and now need to get the number on the line and associate it with a variable.

I tried the following but it drops a number off.

String data = "\n\rFred is 100\n\rWilma 5\n\rBarney is 999";
String data1[] = data.split("\n\r");

 Pattern p = Pattern.compile("\\s\\d");

        for (String bd : data1) {
            String[] result = p.split(bd);
            for (String b2 : result){
                System.out.println(b2);
            }
        }

Giving me:
Fred is
00
Willma

Barney is
99

Any thoughts?

The number is part of the splitting regex and will therefore not show up in the non-matched parts. Take a look at the Javadoc of Pattern for how (positive) lookahead works.

Rob,

Thanks that was the guide point I needed.

This worked:

Pattern p = Pattern.compile("\\s(?=^\\d)*");

Seems to me like the line terminator pattern doesn't quite cut it either.

Jelle,


It seemed to work for me, did I miss something as to why does not quite work?

For the hard-coded String it'll work like a charm, unfortunately it won't successfully match line terminators for text files created on Windows, Unix (based) and older Mac OS operating systems. See http://en.wikipedia.org/wiki/Newline.

Okay, thanks. I was not worried about OSs. (though I did not say that upfront.) And I did not catch that as an issue or even think about it, which I need to remember.

I am pulling data from a serial device. The coded strings are surrounded by newlines and returns.

Thanks
Mike

Sometimes it's easier and faster to do some old-fasioned parsing.
