Replace function

[Justin]

I need to replace an expression that occurs from time to time when parsing a file.

How would I replace every occurrence of \r\n****\r\n with nothing ""

So it would be a line return (\r\n) a 4 digit (numbers and letters) identifier then a line return(\r\n). Replace that with just blank (basically remove it).

Example would be \r\n1e25\r\n or
1e25

And then it would remove that whole thing from the string.

I'm not too good with regular expressions how would i go about that?

Thanks

String has a function replaceAll() use that and it should take care of ur issue

[Justin]

ya i know... what would the regex be?

"\r\n....\r\n"

Something like that?

here it is , as simple as it can possibly get.

String d = "\r\n1e25\r\n\r\n2e26\r\n\r\n3e27\r\n\r\n4e28\r\n";
//there are 2 simple ways you can do it with, use split method or replaceAll

System.out.println("["+d+"]\n["+d.replaceAll("\r\n"," ")+"]");
