Re: [xsl] Inverting names with Jr and Sr considered

["Mark" <mark@xxxxxxxxxxxx>]

I agree, my specification is likely not complete. However, my input is a 
single document written by one person indexing a single journal. There is a 
great deal of consistency to the data and I doubt that there are as many as 
1000 names. That said:

I received an answer off the list (thus do not feel authorized to post it 
here) that will help me discover what oddities I have not covered. It 
explained the regex expressions it used so that perhaps if modification is 
required, I may be able to do it.

Thanks for your time, Michael; as always this list provides the most 
consistent and practical advice around, something you all can be proud of.

I wouldn't even attempt to write any code based on this as the
specification. For this to work at all well, you're going to need to
iteratively adapt the solution to handle all the names in your dataset,
or at least a sample of a couple of thousand of them. There's just too
much variation in the names you might encounter. Are "Jr" and "Sr"
really the only suffixes, and are they always spelt this way, or do you
also get "III" and "Jnr" and "Jnr."?

If I'm wrong, and the names are all regular and in the pattern you
describe, then I think you can just tokenize on whitespace and do
something like

suffix := $tokens[last()][. = ('Jr', 'Sr')]
stem := if ($suffix) then remove($tokens, count($tokens)) else $tokens
value-of select="concat($stem[last()], ',']), remove($stem,
count($stem), if ($suffix) then concat('(', $suffix, ')') else '')"
