QRegExp Problem

Hi all QT experts,

I have this example String:

msg = "(<4>)(-<5>)"

so I tried to filter the strings between the ( ) like this,

QStringList part = StringList:.split(QRegExp("(*)"), msg);

my expected List would be:
<4>
-<5>

but I get this:

(<4>
(-<5>

I like to do the same with the < > after I have filtered the strings inside
the ( )

what expression do I have to use?

thx andy

You are not using regular expressions correctly.  Regular expressions are
_not_ the same as filename globs. Use the following to split on the ')'
and '(' correctly:

QStringList part = StringList:.split(QRegExp("[()]"), msg);
