source writer transformer
Ok, as has been suggested, simple questions, single question per e-mail.
Can I do this?
Http Generator
Transformer to basically aquire a particular <img> tag within the doc.
something or the other to go "get" the image
source writing transformer to store the image on disk
<img> tag with src= pointing to the cached copy in the resulting xhtml doc.
thanks,

well, it's for comic strips. I have an existing "solution" in perl, but
it's slow/ugly/hard to modify, thought it would be fun to move. The
sites only give a month of history; i sometimes like to look back, ya know?
Anyway, I was afraid of this. Probably the thing to do is to use cocoon
to write the main stuff, but make an action in java to actually fetch
the image. Thanks, though for your help.

So you need more than a simple caching of the images or what does
"archive" mean? You should not assume to have access to the cache, you
would need another approach then.
But Cocoon is not for handling images/binary data, so it's for example
not possible to use the source writer transformer. Something that
*might* work is the usage of PipelineUtil.processToStream() in
flowscript, with a pipeline containing a reader reading the remote
image, and handling the storage on disc by the flowscript.

Eh, it'd work fine if i knew where cocoon stores the images. I want to
archive them, then....

It does not sound undoable. You want to rewrite the original document
and replace the original image references with references to your stored
images? And using Cocoon as proxy only (for xhtml *and* images) and
letting the rest be done by caching does not help? The latter sounds
easier to implement.
