Re: XSLT: question re testing for possibly empty eleme

  test="string-length(anElement) > 0">

that is the same as 

  test="string-length(anElement)">


and tests if the string length is non zero

so <anElement/> and <anElement><x/><y/></anElement> are both false and
<anElement>z</anElement> is true


  But couldn't you rewrite that as

  <xsl:when test="anElement">

No that tests if teh element is there so all the 
so <anElement/>  <anElement><x/><y/></anElement>  and
<anElement>z</anElement> are all true

Probably intended meaning is


  test="anElement/node()">


which tests if the element has children so

so <anElement/> is false and a<anElement><x/><y/></anElement> and <anElement>z</anElement> are true
