Question

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

Answer 1

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

Remove .nodeValue from your code.
