You can use Zlib::GzipReader.open with a block. (Since I set Chris the 
original problem, and this isn't the hard part, I'll show the code that 
is used in the app, with a couple of minor mods to make it look like 
Chris's example.)

Zlib::GzipReader.open(@tarfile) { |tgz|
  Archive::Tar::Minitar::Reader.open(tgz).each do |entry|

# Chris's code
#    fpl = StringIO.new( entry.read) if entry.name =~ 
/#{@date}#{channel}_pl/
#    fpi = StringIO.new( entry.read) if entry.name =~ 
/#{@date}#{channel}_pi/

# Or test the verification by using the XML document directly
#   fpl=REXML::Document.new(StringIO.new(entry.read)) if entry.name 
=~/#{date}#{channel}_pl/
#   fpi=REXML::Document.new(StringIO.new(entry.read)) if entry.name 
=~/#{date}#{channel}_pi/

  end
}
