better way to get a sibling?

hello.

I have XML such as:

<data>
        <row id="1">
                <field name="question_id">5</field>
                <field name="answer">1</field>
                <field name="total">45</field>
        </row>
</data>

and xpath:

//field[@name='question_id'][text()=$q_id]/../field[@name='total']

if I have $q_id defined as 5, is this the best way to query the total if given the question id?
