Hi hippo!

no, it is not HTML. It is some interface using some formatting strings like (!!like!!) HTML. But unfotunately the interface crashes if some "<>" strings are included which do not match the allowed formatting strings.

The strings I process are lines from logfiles. Unfortunately some of these lines include "<xxx>" strings. This brings the interface I use into trouble. So I need to filter them out.

I meanwhile found out I get a "true" if I use the following code:

$av_tmp_STRING = "xxx<pre>xxx<www>xxx<strong>xxx";
if ( $av_tmp_STRING =~ m/<(?!strong>)(?!pre)/ )
{
  #do something with the string which contains wrong patterns
}

Still testing if it really works

But anyhow. I will keep the example in mind for other use!

Thanks

Regards Kallewirsch
