XML Javascript parser issue

Question

test [_nObjectives] .pool [j] .feedbackCorrect = oQuestions [j] .getElementsByTagName ("feedbackCorrect") [0] .firstChild.data;

and the XML in this case contains the following:

  <feedbackCorrect>
  </feedbackCorrect>

Running this line of code produces the following error: Message: Object Required

I do not understand. The tag is there, if it is empty, an error occurs and even has spaces, this does not work.

you are getting error because

oQuestions[j].getElementsByTagName("feedbackCorrect")[0]

returns this tag and .firstChild returns null because it has no children ...

Are you sure you don't want

oQuestions[j].getElementsByTagName("feedbackCorrect")[0].data

?

but why does it work when the xml looks like this:

<feedbackCorrect>any value</feedbackCorrect>

?
