[xsl] looking for best way to group elements

[Bill French <bfh@xxxxxxxxxxxxx>]

Hi,

I'm struggling to transform XML that looks like this:

<group name="Languages" displayName="Languages" order="4">
    <field name="ppl_language" displayName="Language"> Spanish </field>
    <field name="ppl_language" displayName="Language"> Portuguese </field>
    <field name="ppl_language_native" displayName="Native?"> Yes </field>
    <field name="ppl_language_native" displayName="Native?"> No </field>
    <field name="ppl_language_speak" displayName="Spoken"> Fluent </field>
    <field name="ppl_language_speak" displayName="Spoken"> Functional 
</field>
    <field name="ppl_language_write" displayName="Written"> Fluent </field>
    <field name="ppl_language_write" displayName="Written"> Survival 
</field>
</group>

What I need is output that looks like this:

Language: Spanish
Native?: Yes
Spoken: Fluent
Written: Fluent

Language: Portuguese
Native?: No
Spoken: Functional
Written: Survival

That is, the source document contains <field/> elements that are 
returned grouped by their @name attribute values. The <field/> elements 
are always returned in the order stated above, ppl_language, 
ppl_language_native, ppl_language_speak, and ppl_language_write. There 
can be an arbitrary number of language entries in the list, but it is 
guaranteed that for every entry, all four <field/> elements will exist.

I am having trouble devising a strategy/writing a match pattern to group 
the elements correctly. Can anyone make a suggestion? Obviously, the 
problem is that there is only one <group/> element that is the parent 
for all <field/> elements, no matter how many <field/> elements there 
are. I'm using XSLT/XPath 2.0.

Best regards,
