getAttribute("rel") has no properties

[christopher.secord]

I'm having a hard time understanding an error that I'm getting. In the
code below, I'm trying to call substring() on an attribute of an
anchor. The error I get says "getAttribute("rel") has no properties"

The reason this confuses me is that getAttribute("rel") returns a
string, so it should have all the properties and methods of a string,
right?? What am I missing here?

var AnchorArray = document.getElementsByTagName("a");

for (var i = 0; i < AnchorArray.length; i++) {

if (AnchorArray.getAttribute("rel").substring(0,5) == "other")
alert("hi there");

}

The error you get (getAttribure('rel') has no properties), means that
in thise case, getAttribute('rel') didn't return a string, but null,
or 'undefined'. None have any properties, hence the error message.

You may try using :
if (AnchorArray.hasAttribute('rel') && [...])
{
[...]
}
