XML responseText missing opening tags and other data

XML responseText missing opening tags and other data

for some reason when I get data back from a particular web service, it is missing opening xml tags and a bunch of other XML data. I have removed sensitive data and only included a portion of the response body but you should get the idea.

here is what I get in responseText:
"Ok<\/resultCode> I00001<\/code> Successful.<\/text><\/message><\/messages>... "

here is what I should get:
<getTransactionDetailsResponse 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd">
    <messages>
        <resultCode>Ok</resultCode>
        <message>
            <code>I00001</code>
            <text>Successful.</text>
        </message>
    </messages>...
