Didn't see that, but that would make the minimal format for parsing a
comma, or any other single character marker, and the minimal would
still be a specific marker in a file, but does not answer my question
about the assignment to another file's variable.
If file a.xml has simple tagged xml like <a>, and file b.config has
tags that represent the a.xml(i.e.<a> = <antonym>) as greater tags,
does this pattern optimize the process by limiting the size of the
tags to be parsed in the xml, then converting those simpler tags that
are found to the b.config values for the simple <a-z> simple format?
