Subject: Merge XML documents with Ruby

Dear group,

Currently I'm working with Ruby to merge several XML documents into
one. I'm using Builder to construct the 'master' XML file:

    x = Builder::XmlMarkup.new(:indent => 2)
    x.instruct! :xml, :version => "1.0", :encoding => "UTF-8"
    result = x.header do |xml|
      some_hash.each do |key, values|
        xml.company(key)
        values.each do |value|
          xml.department(value.to_xml)
        end
      end
    end

However on the spot where I write 'xml.department' trouble strikes.
The 'value' already responds to the to_xml method and generates
perfectly fine XML. I'd like to insert that XML into the master file.
If I do it the way displayed above the department tag appears twice
(once from the xml.department call and once it is used as the header
tag of the department.to_xml result). Moreover the instruct tag is
inserted and all < and > characters are escaped.

Is there anyway of doing this gracefully?
Any help is greatly appreciated.

With kind regards,
Harm
