Cannot read property 'nodeValue' of null

I have XML:

<street></street>

or

<street>2813 Bla ave</street>

Javascript:

if ((xmldoc.getElementsByTagName('street')[i].firstChild.nodeValue != null)) {
                 alert(1);
                 }
                 alert(2);

But the script doesn't work - Cannot read property 'nodeValue' of null

Use xmldoc.getElementsByTagName('street')[i].innerHTML because the text you want is between the tags. I believe this IS supported for XML. Of course, you could always use the nodeValue property as well.

The street node does not have any children. You need to remove .firstChild

Your selector is failing, 

 xmldoc.getElementsByTagName('street')[i].firstChild

appears to return null. Have you tried logging and checking to make sure that the selector you want actually exists?

nodeValue will never be null because without a value the node wouldn't exist.

Remove .nodeValue from your code.
