hi,
i think it has to do with the multiline flag. that causes it to eat the
newline (read the javadocs). i don't see any neat way to do it, other
than treating whitespace and newlines separately. for example,
something lime
String s1 = "hello\n hello\n\n hello\n hi\n";
Pattern p = Pattern.compile("^[ \t]+|[ \t]+$|\n$",
Pattern.MULTILINE);
Matcher m = p.matcher(s1);
s1 = m.replaceAll("");

I am trying to strip all whitespace from "each line" in a EditText
View. The _expression_ I am using is this
String result = Pattern.compile("^\\s+|\\s+$",
Pattern.MULTILINE).matcher(input).replaceAll("");
This works for the following input
------------------------
hello
hello
hello
hi
------------------------
This will produce:
hello
hello
hello
hi
but
------------------------
hello
hello
hello
hi
------------------------
will produce:
hello
hellohello
hi
Notice the new line (\n). This is causing the problem. What I want
is:
hello
hello
hello
hi
Any ideas about how to fix this?
