Hi Gerardo,
Here's a link to a previous discussion about this:
http://marc.theaimsgroup.com/?t=10154269536r=1w=2
The short answer is that you can't pass a request-time parameter to a
serializer; you can only pass configuration-time parameters (in the
map:serializer element, when you define your serializer components), but
that probably won't work for what you're trying to do.
One kind-of-ugly solution mentioned in the above discussion is to have a
previous component in the pipeline (such as a transformer or generator) read
the parameter and stick it into the XML, which would allow your custom
serializer to read it out of the XML. Not the prettiest thing, but it does
work...
Anyway, sorry I don't have a better answer.
Harry
PS There was also mention of a FileWritingTransformer, but I believe that's
in the scratchpad. Might be worth checking out, though.

Subject: Retrieving sitemap paramters in a serializer
I'm sorry if this is a stupid question, but I can't seem to figure out how
to get the Parameters object to a serializer. I have a pipeline that has a
parameter that I am trying to access from within the serializer. The code
for both is below. The serializer is just trying to write the file to
disk. I'm sure that this type of serializer must have been written
already, but I couldn't find it anywhere and it doesn't seem that hard.
Any help would be greatly appreciated :)
