Java xpath, select most deep children

Question

I'm new to Java and XPath syntax. I have complex xml document. What I need is to select all the nodes, that don't have children (I need their values actually).

<root>
    <a>
        <b>text1</b>
        <c>text2</c>
    </a>
    <d>
        <e>
            <f>text3</f>
        </e>
    </d>
    <f>text4</f>
</root>

I want to get list "text1","text2","text3","text4" here. Could you help me with XPath expression?
