Hello Martin,

I applied this XPath expression 

      //head

to this XML document

<Document>
   <head>
       <head>B</head>
       A
   </head>
</Document>

using oXygen (where SAXON is the XPath processor) and got these results:

A
B

That is, the results are in non-document order.


You've asked for two <head> elements but you haven't said how you want them 
displayed; that decision is being made by Oxygen. I don't know why it's 
choosing to display the two <head> elements in this way, but it's quite outside 
the scope of the XPath specification.
