How do I get the attribute value of an XML node with Javascript / jQuery?

I'm trying to get the value of the duration attribute on the node, then get the 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>'

So far I've got:

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);

};

The second console.log prints undefined.

The first problem I ran into is that currLoadXml is not a string. It needs to be wrapped inside single quotes.

Try using the below method

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);

        }

    });



};
