How to group some records by a specific value

Hi all,
 
I have some instance data that looks like this for input of an xforms:
<xforms:instance id="mydata">
<data>    <record><name>name1</name><type>A</type></record>    <record><name>name2</name><type>A</type></record>    <record><name>name3</name><type>A</type></record>    <record><name>name4</name><type>B</type></record>    <record><name>name5</name><type>B</type></record>    <record><name>name6</name><type>C</type></record>    <record><name>name7</name><type>C</type></record></data></xforms:instance> I would like to obtain a result like :Type A            name1            name2            name3Type B            name4            name5Type C            name6            name7 I think it is possible using a repeat, but I don't know how.Could you please help me ? Tanks in advance, Catherine
