I think that's not exactly correct. You can use "@" to access non-existence attributes but cannot
use it for filtering.
With the OP example,
trace(_co...@instance);
...should not generate an error but you'd get an error with:
trace(_conf.(@instance == "boo"));
...so instead this should be us
Unfortunately, that doesn't work. That returns something (an empty XMLList, I
believe).
The best way to test for attribute existence and/or if it has a value is what I
wrote.

You're suggesting to write more code to do the same thing. Why should
anyone write more code to do the same thing?
With the above comment in mind - I was trying to do if(no...@attribute)

hasOwnProperty does not tell you whether it has a length, though. It only
checks for existence.
And for some reason, it looks like you modified my code when quoting me:
>> if (node.hasOwnProperty("instance").length() > 0)
I didn't write that code, which would error since a Boolean doesn't hav
The Top Level XML class actually has a function, called hasOwnProperty that
exists for this purpose.
However, to answer your question exactly, it returns a value of undefined.
This is not null or "" it is it's own return type, as this relates to XML
(which by definition is an object) and objects a
You will get runtime errors when attempting to access an attribute that isn't
there. The proper way to check for existence and length of an attribute is to
use the .attributes() syntax as such:
if (node.attribute("instance").length() > 0)

Yeah, I agree, it's overly verbose.

It's because in E4X:
someNode.length
Means get this node:
Aha, I see now - bit of a waste of code too.
And who's bright idea was it to use length for Strings and Arrays, but
length() for XML / e4x?

Hi,
I am having problems parsing some XML config files and testing for
empty attributes. There is an example xml below.
Problem is that I am asking for the following:
_co...@instance
Which is returning a value, but I am not sure what type of value.
Should this return null,
