Re: processing alternating sibling nodes

------------------------------------------------------------------------
I am having trouble getting the following xml tree to simply write out
it's contents in the order that it appears:
------------------------------------------------------------------------
<home>
 <problem>
   <question>
     <text>text content 1</text>
     <reference>ref content 1</reference>
     <text>text content 2</text>
     <reference>ref content 2</reference>
     <text>text content 3</text>
     <reference>ref content 3</reference>
     <text>text content 4</text>
     <reference>ref content 4</reference>
     <text>text content 5</text>
   </question>
 </problem>
</home>
------------------------------------------------------------------------

------------------------------------------------------------------------
The output I would like to get is this:
------------------------------------------------------------------------
text content 1
ref content 1
text content 2
ref content 2
text content 3
ref content 3
text content 4
ref content 4
text content 5
------------------------------------------------------------------------

#
<?xml version="1.0"?>
<transform
  version="1.0"
  xmlns="http://www.w3.org/1999/XSL/Transform">
  <output method="text"/>
</transform>
#

      text content 1
      ref content 1
      text content 2
      ref content 2
      text content 3
      ref content 3
      text content 4
      ref content 4
      text content 5
