hey all,
I have a foaf.xml that looks like that:


<rdf:RDF xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:foaf="http://xmlns.com/foaf/0.1/"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

        <foaf:page>
            <foaf:Document rdf:about="http://myself.videntity.org/" />
        </foaf:page>
        <foaf:nick>myself</foaf:nick>
        <foaf:mbox rdf:resource="mailto:myself / gmail.com" />

        <foaf:knows>
            <foaf:Person rdf:about="http://bob.videntity.org/">
                <foaf:name>bob</foaf:name>
                <foaf:homepage rdf:resource="http://bob.videntity.org/" />
            </foaf:Person>
        </foaf:knows>
        <foaf:knows>
            <foaf:Person rdf:about="http://bill.videntity.org/">
                <foaf:name>bill</foaf:name>
                <foaf:homepage rdf:resource="http://bill.videntity.org/" />
            </foaf:Person>
        </foaf:knows>
    </foaf:Person>
</rdf:RDF>


I put all this into a string @f and then I create a doc:

doc=Document.new(@f.body)
@foaffriends=doc.root


I'm trying to get the names of all my friends:
"bill" and "bob"

If I do:

@foaffriends[1].elements['foaf:knows'][1].elements['foaf:name']


I get "bob" but I can't figure out how to get "bill".
I tried:


@foaffriends[1].elements['foaf:knows'][2].elements['foaf:name']


but it returned nil.

Any idea how to get all my friends name?

thanx in advance

Pat
