Message: Object required error when querying XML in JavaScript

Question

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

and the XML in this case contains this:

  <feedbackCorrect>
  </feedbackCorrect>

When executing that line of code the following error occurs: Message: Object required

I don't get it. The tag is there, if it is empty the error occurs and even has spaces chars it doesn't work.

you are getting the error because

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

is returning that tag, and the .firstChild is returning null, because it has no children...

Are you sure you dont want

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

?
