Answer 1

    table_data = []
    xml = File.read('file1.xml')
    doc, posts = REXML::Document.new(xml), []
    doc.elements.each('resultset/row') do |table_row|
      table_data << {:table_name => table_row.elements[1].text,
        :record_count => table_row.elements[2].text,
        :size_in_mb => table_row.elements[3].text
      }
    end
