Trouver les valeurs d'attribut xml avec javascript

Comment puis-je obtenir la valeur de l'attribut d'un nœud XML, Javascript /jQuery?

Je vais essayer d'obtenir la valeur de l'attribut de durée sur le nœud, puis obtenir le fixedValue.

<loanAmount>
    <interestRates>
        <interestRate allowInterestOnly="true" type="variable" value="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="1" fixedInterestOnlyValue="5.7" fixedValue="5.7" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="3" fixedInterestOnlyValue="5.75" fixedValue="5.75" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="5" fixedInterestOnlyValue="6.64" fixedValue="6.56" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="10" variableInterestOnlyValue="5.82"/>
    </interestRates>
</loanAmount>'

Pour l'instant j'ai:

var currentLoanRates = function() {
    var currLoanXml = '<loanAmount><interestRates><interestRate allowInterestOnly="true" type="variable" value="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="1" fixedInterestOnlyValue="5.7" fixedValue="5.7" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="3" fixedInterestOnlyValue="5.75" fixedValue="5.75" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="5" fixedInterestOnlyValue="6.64" fixedValue="6.56" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="10" variableInterestOnlyValue="5.82"/></interestRates></loanAmount>',
    xmlDoc = $.parseXML( currLoanXml ),
    $xml = $( xmlDoc ),
    $intRate = $xml.find("interestRate"),
    $varIntRate = $intRate.attr("fixedValue");

    console.log($intRate);
    console.log($varIntRate);
};

La deuxième console.journal imprime undefined.
