kristinu, does psxy accept - as a filename indicating that it should read from standard input?
If it does, you can execute psxy inside an awk script feeding it the portions of your input file between the (>) separator line without creating intermediate files.

NAME
archive - Usenet article archiver SYNOPSIS
archive [ -a archive ] [ -f ] [ -i index ] [ -m ] [ -r ] [ input ] DESCRIPTION
Archive makes copies of files specified on its standard input. It is normally run either as a channel feed under innd(8), or by a script before expire(8) is run. Archive reads the named input file, or standard input if no file is given. The input is taken as a set of lines. Blank lines and lines starting with a number sign (``#'') are ignored. All other lines should specify the name of a file to archive. If a filename is not an absolute pathname, it is taken to be relative to /var/spool/news. Files are copied to a directory within the archive directory, /var/spool/news/news.archive. The default is to create a hierarchy that mim- ics the input files; intermediate directories will be created as needed. For example, the input file comp/sources/unix/2211 (article 2211 in the newsgroup comp.sources.unix) will be copied to /var/spool/news/news.archive/comp/sources/unix/2211. OPTIONS
-a archive If the ``-a'' flag is used then its argument specifies the directory to archive in instead of the default. -f If the ``-f'' flag is used, then all directory names will be flattened out, replacing the slashes with periods. In this case, the file would be copied to /var/spool/news/news.archive/comp.sources.unix/2211. -i If the ``-i'' flag is used, then archive will append one line to the specified index file for each article that it copies. This line will contain the destination name and the Message-ID and Subject headers. -m Files are copied by making a link. If that fails a new file is created. If the ``-m'' flag is used, then the file will be copied to the destination, and the input file will be replaced with a symbolic link pointing to the new file. -r By default, archive sets its standard error to /var/log/news/errlog. To suppress this redirection, use the ``-r'' flag. EXIT STATUS
If the input is exhausted, archive will exit with a zero status. If an I/O error occures, it will try to spool its input, copying it to a file. If there was no input filename, the standard input will be copied to /var/spool/news/out.going/archive and the program will exit. If an input filename was given, a temporary file named input.bch (if input is an absolute pathname) or /var/spool/news/out.going/input.bch (if the filename does not begin with a slash) is created. Once the input is copied, archive will try to rename this temporary file to be the name of the input file, and then exit. EXAMPLES
A typical newsfeeds(5) entry to archive most source newsgroups is as follows: source-archive :!*,*sources*,!*wanted*,!*.d :Tc,Wn :/usr/lib/news/bin/archive -f -i /usr/spool/news/news.archive/INDEX HISTORY
