I have another small problem with sam and regexp. I have a text
with a lot of constructs like this one:

Hello world http://my.domain:"This is a link" more text and
http://another.domain:"This is another link" follows more text

Now I try to translate the link in html syntax with
,x/(http.*)\:\".*\" s/(http.*):\"(.*\n*.*)\"/<a href=\"\1\">\2<\/a>/

The problem is, that the regexp matches both "links" not only
the first ore the second one. I've tried to find a better one but
its hopeless. ;-)

Thanks for any hint
Matthias

your problem is that .* is greedy. instead of
  .*"
(maximal sequence of anything followed by quote)
write
  [^"]*"
(maximal sequence of not-quote, followed by quote).
you don't need the backslashes for : and ".

x (and y) are iteration operators.  so ...

once you understand them they are extremely powerful.

yes, as it always has been (ie. not a sam related problem).
