I added my own wrapper script that calls the grabber script.  I use this from the command line and from the cron job.  It manages the temporary file part outside of the grabber script.  It also validates the resulting XML file generated by the grabber script, because if the grabber script fails for some reason the XML file is left syntactically incorrect, which might cause MythTV frontend problems when trying to parse it.


	echo "Starting Apple Movie Trailers update at " `date`
	/usr/bin/php -q $HOME/bin/myth_trailers_grabber > $HOME/appletrailer.tmp
	if [ $RC -eq 0 ]; then
		xmllint --noout $HOME/appletrailer.tmp
		if [ $RC -eq 0 ]; then
			NUMTRAILERS_PREV=`grep '<button' $HOME/appletrailer.xml | wc -l`
			NUMTRAILERS_NEW=`grep '<button' $HOME/appletrailer.tmp | wc -l`
			mv $HOME/appletrailer.tmp $HOME/appletrailer.xml
			echo "Update successful."
			echo "  Had $NUMTRAILERS_PREV trailers."
			echo "  Have $NUMTRAILERS_NEW trailers."
			# TODO: Look in the grabber script.  If using download, 
			#       check download directory.  If exists, count the
			#       number of files there and report them.
			echo "xmllint failed: $RC"
		echo "myth_trailers_grabber failed: $RC"
	echo "Completed Apple Movie Trailers update at " `date`

update_trailers >> $LOGFILE 2>&1

Is there a way to make the XML file contain entries for all of the trailer files in the download directory instead of just the last 20 trailers downloaded?
