[xsl] Generating a collection of unique elements.

[Nathan Potter <ndp@xxxxxxxxxxxxxxxxxxxx>]

Greetings,

I have thought about this for a couple of days, and I don't really  
have an ideas about how to get the result I want. Maybe someone here  
can help!

In my source document there are a number of <foo> elements. They all  
have a "name" attribute. They can occur as child elements of any other  
element in the document, at any level of nesting.

My XSL needs to process these <foo> elements and produce a list of the  
unique names.

Source Example:

<doc>
    <foo name="a" />
    <foo name="d" />


    <thing1>
        <foo name="a" />
        <foo name="b" />
        <foo name="c" />
    </thing1>

    <thing2>
            <foo name="a" />
        <thing3>
            <foo name="b" />
            <foo name="c" />
        </thing3>
            <foo name="d" />
            <foo name="e" />
    </thing2>
</doc>


Desired Result:

<newDoc>
    <a />
    <b />
    <c />
    <d />
    <e />
</newDoc>


Anybody have a suggestion?


Thanks,

Nathan
