Hi,

Sorry, Im really stuck here. *who* has no parent ? The node in the for 
statement ($town) ?

BTW, having tried this :

let $a :=
<root>
<county name="Devon">
     <district name="East Devon">
         <town name="Axminster" pct="East Devon">
             <town name="Abbey Gate"/>
          </town>
         <town name="Aylesbeare" pct="East Devon"/>
     </district>
</county>
</root>

let $b :=
for $town in $a/county/district/town
where ($town/../@name eq "East Devon")
return $town

let $c :=
for $town in $a/county/district[@name = "East Devon"]/town
return $town

return 
(<attribute>{$a/county/district/town/@name}</attribute>,$b,<blah/>,$c)

... I get :

<?xml version="1.0" encoding="UTF-8"?>
<attribute name="Aylesbeare"/>
<town pct="East Devon" name="Axminster">
    <town name="Abbey Gate"/>
</town>
<town pct="East Devon" name="Aylesbeare"/>
<blah/>
<town pct="East Devon" name="Axminster">
    <town name="Abbey Gate"/>
</town>
<town pct="East Devon" name="Aylesbeare"/>

Where does <attribute name="Aylesbeare"/> come from ?

Cheers,
