Can anyone tell me how to get sed to work with an OR pattern match?
If I try the standard pipe character, the command fails. I found on
Google to escape the pipe with a backslash. That command runs, but
the pattern doesn't match.

Here's what I have that works (just one pattern):
sed 's|<Tag />|<Tag>Value</Tag>|' file_path

This command runs but doesn't match either pattern:
sed 's|<Tag />\|<Tag></Tag>|<Tag>Value</Tag>|' file_path

I haven't tried doing an OR in a single pattern. But, the
following is what I use to successfully execute more than one pattern at a
time. (Variable substitutions are performed before I use the string in
QSH.)

sed -i -e 's|~&1|~&2|g' -e 's|_&1|_&2|g' &path
