Imagine the following XML document:

<root>
    <person_data>
        <person>
            <name>John</name>
            <age>35</age>
        </person>
        <person>
            <name>Jim</name>
            <age>50</age>
        </person>
    </person_data>
    <locations>
        <location>
            <name>John</name>
            <country>USA</country>
        </location>
        <location>
            <name>Jim</name>
            <country>Japan</country>
        </location>
    </locations>
</root>

I then select the person node for Jim:

XmlNode personNode = doc.SelectSingleNode("//person[name = 'Jim']");

And now from this node with a single XPath select I would like to retrieve Jim's location node. Something like:

XmlNode locationNode = personNode.SelectSingleNode("//location[name = {reference to personNode}/name]");

Since I am selecting based on the personNode it would be handy if I could reference it in the select. Is this possible?.. is the connection there?

Sure I could put in a few extra lines of code and put the name into a variable and use this in the XPath string but that is not what I am asking.
