[Pywikipedia-l] replace.py - how to narrow down the results?

[Chris Watkins]

Next question:  If I have a set of synonyms in the wiki, and they redirect
to the same page (say, cow and cattle), is it possible to find the first
time any of these terms occur on a page, and link only that? So cow would be
changed to [[cow]], or cattle to [[cattle]], but not both on the same page,
if both terms occur.


Many thanks Daniel, this has been a great help - and adding the
-exceptinsidetag:header  to regex thanks to my request is very good of you.

I have been doing test runs (without saving, as my bot has a problem at the
moment) and I am able to successfully use all these terms that you gave.
This is wonderful.

Chris
