Javascript / jQuery で XML ノードの属性値を取得するにはどうすればよいですか?

ノードの期間属性の値を取得してから、fixedValue を取得しようとしています。

<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>'

これまでのところ、私は持っています:

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);
};

2 番目の console.log にはundefinedが出力されます。

最初に遭遇した問題は、currLoadXml が文字列ではないことです。一重引用符で囲む必要があります。

以下の方法を試してみてください

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");
    $intRate.each(function(index, element) { 
        if(element.attributes["duration"]) {
            console.log("Duration :" + element.attributes["duration"].value);
        }

        if(element.attributes["fixedValue"]) {
            console.log("Fixed value:" + element.attributes["fixedValue"].value);
        }
    });

};
