No, I was talking about the return value of 'make'

But the problem is that we can't use in the (from) since some
feeds will contain only, what do we do about that?
In most cases it will still be and then the subsequent test for
item (in the terminating tag) will of course return true and then we
get nothing.
I mean I don't understand how the a

Maybe this is clearer, so obviously we can't use t

I started with this approach yesterday, first in order to capture feed
type which I am now able to do.
I noticed that some rss feeds have attributes in their tags,
therefore the above won't work 100% of the time.

(while
(from "")))

Ouch
It's a good question with a very simple answer, many many feeds out
there are completely broken, sometimes they don't conform to
standards, that's a good scenario but often they have unmatched tags
or unclosed attributes.
At first I tried using the xml function but I quickly discovered that
it bre

Alex and I had a discussion on IRC regarding match and long lists,
here is a short recap and example of a string Alex can use instead of
that massive rss.xml I attached earlier.
The problem is using from in combination with till repeatedly to parse
input in order to for instance get at the content

What I'm subsequently doing further "down" in the code is a recursive

Hi Henrik,

Thanks. Unfortunately, I cannot reproduce it. I even checked with my
special GC check setup, where a garbage collection is performed before
each 'cons'. This usually shows errors in the data handling (though such
a test runs for hours).
