Hmm. Good question! :) Let's think this through. The way to negate a "grep" is to pass through, unmodified, any line modified by the grep, and suppress any line _not_ modified. But the original definition of <unmodified> was to let through only lines not modified by the nested filter. So these definitions are at odds with one another. Are there any other use cases for negation other than negation of line contains type filters? Maybe it would be best (if unexciting) to add negation logic to these few classes. :( > > -Matt > > > > > > > > > By all means, be my guest Matt ;-) --DD > > > > > > > > On 7/11/06, Matt Benson <[EMAIL PROTECTED]> > > > wrote: > > > > > --- Dominique Devienne <[EMAIL PROTECTED]> > > > wrote: > > > > > > > > > > > this are not conditions, but filters. > There's > > > no > > > > > > <not>. > > > > > > > > > > > > I guess a negate attribute on > > > <linecontains[regexp]> > > > > > > would be > > > > > > required, or a <unchanged> weird pseudo > filter > > > that > > > > > > accept a nested > > > > > > filter, and 'reverses' the nested filter's > > > job, by > > > > > > accepting only > > > > > > lines unchanged by the nested filter. > > > > > > > > > > Hmm...
