Thank you for the many responses.

I learned about minimalistic searching, which I had not used before and so
did not think to apply to this problem.  This is probably what I thought I
was missing.

I learned that maybe my approach was limited and I should learn to use
htmllib.  Probably the way I am doing it now is only suitable for large
tables of data and should be limited to that.

In the meantime, I used span twice and extracted the string that way.  This
does not require special sentinels either since I can search for the
beginning tag and for the end tag.

Thank you again.
