Ah, never mind. Let me just publish one entry from the script's prefs file:
# yaml preferences for FeedMaker
# This file is read in and written by the FeedMaker python script

md5_tag: <span class="titleHd">
The script takes that in, checks the specified tag's content, spits out an rss feed, and updates three fields in the preferences: etag, last_modified (for bandwidth-friendly conditional GETs), and md5 (fingerprint of specified tag's data). I've got two sites so far, but now I can at least have my machine easily monitor sites that don't publish their own feeds.
