[xml.rb]
require 'dbi'
DBI::Utils::XMLFormatter.table(dbh.select_all("SELECT * FROM people"))
[/xml.rb]

When I run this from the dos prompt, I do get the appropriate output, IE:
c:\scripts>ruby xml.rb
 <?xml version="1.0" encoding="UTF-8" ?>
   <rows>
   <row>
     <id>1</id>
     <name>Wanda</name>
     <height>62.5</height>
   </row>
   <row>
     <id>2</id>
     <name>Robert</name>
     <height>75.0</height>
   </row>
c:\scripts>

But from within the script, I'm unable to capture this output as a
string, for example:
irb> require 'dbi'
irb> asdf = DBI::Utils::XMLFormatter.table(dbh.select_all("SELECT *
FROM people"))
irb> puts asdf
=> #<IO:0x2c18968>
[/xml_borked.rb]

I'd like to be able to use puts to output the results of the
DBI::Utils::XMLFormatter method.

Any suggestions?

Thank you
