[basex-talk] Grouping and sorting

14 Aug 2010

      XQuery:
let $type := 
<type>
  <item id="id1"><value>3</value></item>
  <item id="id2"><value>3</value></item>
  <item id="id3"><value>6</value></item>
  <item id="id4"><value>5</value></item>
  <item id="id5"><value>5</value></item>
</type>

for $i in $type/item
let $v := $i/value
group by $v
order by $v return $v

Result in BaseX:
<value>3</value>
<value>5</value>
<value>5</value>

As I understand XQuery the result should be as follows:
<value>3</value>
<value>5</value>
<value>6</value>

Where ist my mistake or is it a bug in BaseX?
