Subject: Re: (DBI::Utils::XMLFormatter) Output results as a string?

I never could get it to work properly... It's like.. when I used the
fourth variable as you suggested, the <rows> component was missing.

IE:

irb> DBI::Utils::XMLFormatter.table(dbh.select_all("SELECT *
FROM people"), nil, nil, asdf)

puts asdf

<>
<row>
   <yada>
   </yada>
</row>
</>

When I threw in the variable as the second paramater, I would get the
<rows> piece but not the <row>.... Hard to expain right now because I
have no db to test it on but at work, this is what happened... Does
this provide enough detail?
