Subject: Question about Nokogiri xpath

I am trying to parse an xml file using nokogiri. If any body has
experience with nokogiri. I request you to help.

Sample xml file.

<database name="TABLE AD_CLIENT">
    <table name="AD_CLIENT" primaryKey="AD_CLIENT_KEY">
      <column name="AD_CLIENT_ID" primaryKey="true" required="true"
type="VARCHAR" size="32" autoIncrement="false">
        <default/>
        <onCreateDefault/>
      </column>
</database>

It can be seen that Column element has two child elements. But when I
use

input = Nokogiri::XML(File.new(file))
input.xpath('//table/column').each do |column|
column.children.length
end


The result is 5.

While the <default/> element is at index 1, element <onCreateDefault/>
is at index 5. Does any one know why this is.

Thanks
venkat
