See if xml has attribute and value

Question

I have some xml that looks like this

<?xml version="1.0" encoding="UTF-8"?>
<html>
   <body>
      <menu>
         <day name="monday">
            <meal name="BREAKFAST">
               <counter name="Hot Cereal">
                  <dish>
                     <name>Oatmeal</name>
                  </dish>
               </counter>
            </meal>
         </day>
      </menu>
   </body>
</html>

I have shortened the xml for this example to make it simpler. Now in javascript I want to check if this xml has value and tags after the meal tag.I am using sax.js xml parser and xmlreader.js to read the xml. Now here is what I have and I am very confused why it is not returning true?

I read the xml and save it as var res And then to check whether there are values and tags after meal tag I do this.

if (res.html.body.menu.day.at(dayNumber).meal) {
     console.log('IT IS TRUE');
}

And it should come true for this xml correct, but it is not what am I missing?

Thanks for the help in advance.

try with this

xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book")[0];

console.log(x.hasAttribute("category"))
