Datacage: Introduced <dc:group epxr="xpath" type="type"> ... </dc:group> and XPath function dc:group-key().
This splits the current result set into groups formed by expr. The type defaults to string.
Afterwards all these groups are iterated by there natural order.
The dc:group-key() gives access to the result of the grouping expression that forms a group.
Say, you have a result set like this:
name | description
-----+------------
a | foo
a | bar
b | baz
b | bla
c | blub
you can use:
<dc:group expr="$name">
<group name="{dc:group-key()}">
<dc:for-each>
<description value="{$description}"/>
</dc:for-each>
</group>
</dc:group>
to create:
<group name="a">
<description name="foo"/>
<description name="bar"/>
</group>
<group name="b">
<description name="baz"/>
<description name="bla"/>
</group>
<group name="c">
<description name="blub"/>
</group>
