Further to my previous message on processing PGN files, I have another
problem. I want to get my own chess rating (it uses a system called
Elo) from a list of my own games in PGN format.

The user name of the players is given by the two fields White and
Black:

[White "black-river"]
[Black "g8wrb"]

and the rating by two fields WhiteElo and BlackElo.

[WhiteElo "1507"]
[BlackElo "1606"]

(the latter two are not part of the PGN standard, but they exist on
the games I have).

Since my username is g8wrb, and g8wrb was black, I need to extract the
BlackElo, which is 1606. Conversely, if I'm white, I want to extract
the WhiteElo. So in the two games below, my rating was 1606 on the
first, and 1594 on the second. Any suggestions how I might print the
BlackElo if g8wrb is black, but print the WhiteElo if g8wrb is white?
