Cannot read property 'xxx' of null

I've got a document fragment with children that I want to loop over (when possible). This is causing an error Cannot read property 'xxx' of null.

How do I test if this will be the case?

You may want to do the following:

if ((documentFragment !== null) && documentFragment.hasOwnProperty('xxx')) {

    // handle property xxx of documentFragment as required

}
