Subject: break from a loop which is run on a xml

how do i loop through a xml and break when i find the node with a
specific value..really struggling to break out of a xml loop..most of
the iterators just loop but cannot be break - ed

please help me with this

for e.g.

this is d code where i find the files in a dir & check d earlier time
stamp for each file which is saved in a xml & do a comparison for each

Find.find('./'){|path|
  if path != './abcd.rb'
    if ! File::directory? ( path )
    modtime = File.mtime(path)
    xmldoc.elements.each("course/file"){ |element|
  oldtime = Time.parse(element.attributes["modified"])
  if modtime > oldtime
        $changed = "yes"
  break
  else
  $changed = "no"
  end
  }
      newfile = course.add_element 'file', {'version'=>'2.0',
'modified'=> modtime, 'download'=>$changed}
      newfile.text = path[2,path.length]
  end
  end
}

this is the sample xml..

<course name='' uniqueID=''  serverURL='' >
<file version='1.0' modified='2011-11-30 16:37:23 +0530' download='no'>
xyzw.pdf
</file>
