Hi,
I would like to offer free sgml validation so folks can parse their web
pages and other sgml documents. (I work on a project that is
developing public domain dtds for corpus tagging) I have been trying
to use procmail but I must be doing something wrong.
Here is what I want it to do:
When someone sends mail to a special user (probably named "parse-me")
it will all be forwarded to me via a mail alias (before procmail gets
it of course, this part is not a problem).
The subject line of the message is the dtd they want used (for
security resons I can't allow any external entites in the document -
wouln't want somewone mailing themselvfs the password file)
so far no problem, all standard stuff.
then, once we have a file with a dtd that matches, I need to take the
body of the message, pipe it through some stuff (sgmls and a fileter
to make it more readable) and then send that file back to the sender,
additionally I would like a log entry of the person that used it and
which dtd they parsed.
This is where I run into trouble. I have been able to get procmail to
detect the message, kik the body off to a temp file, process it into
another temp file and send a reply to the user - but I don't see how to
get the temp file into the reply message!
I have simplified the process for now (for testing) here is what I am
trying. This does put the output into $TEMP2 but it does not include
it in the message. What am I missing?
:0 b c
* ^Subject: HTML3.2.dtd
|cat > $TEMPORARY ; \
sgmls /usr/local/lib/sgml/html.decl $TEMPORARY > $TEMP2 ; rm -f $TEMPORARY
:0 h
* ^Subject: HTML3.2.dtd
| (formail -r -A"Precedence: junk" ; \
cat $TEMP2 )| $SENDMAIL -t
needless to say, I am open to other aproces to solving the problem.
Thanks,
Greg Priest-Dorman
