[xsl] Re: Re: Converting specific child elements into attriutes of parent

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

Sorry, I cannot reproduce the problem -- the transformation runs OK and
produces the expected results -- tried with Saxon 6.5.3, Xalan J 2.4.1,
MSXML4.

The result is:

<customerList>
   <customer>
      <field id="customerId">cust1</field>
      <field id="customerName">Customer  1</field>
      <fieldGroup id="homeAddress">
         <fieldList>
            <field id="street">98th  Street </field>
            <field id="city">Chicago</field>
         </fieldList>
      </fieldGroup>
      <fieldGroup id="companyAddress">
         <fieldList>
            <field id="street">128th  Street</field>
            <field id="city">Chicago</field>
         </fieldList>
      </fieldGroup>
   </customer>
</customerList>


The transformation processes "id" elements before any other elements and
does not depend on any order of the elements in the source xml document.

Which XSLT processor/version are you using?

Are you sure that you copied/pated well (exactly) the xslt code ?
