'How to filter with XPath on all elements without a specific attribute

My XPath is a little bit rusty... Let's say I have this simple XML file:

<?xml version="1.0" encoding="utf-8" ?>
<States xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<States>
<StateProvince name="ALABAMA" abbrev="AL" />
....
<StateProvince name="AMERICAN SAMOA" abbrev="AS" territory="true"  />
</States>
</States>

I would like to run a simple XPath query to parse out all of the true states (so don't pull in states where territory = true). I tried \StateProvince[@territory!='true'] but I got zero. Other variations seem to be failing. This seems like it should be simple, but not finding what I want.

Any help appreciated.

Solution 1:[1]

You are very close:

//StateProvince[not(@territory) or @territory != 'true']

Should get you the result you want.

Solution 2:[2]

This should work:

//StateProvince[not(@territory='true')]

Solution 3:[3]

To find the nodes that don't have any territory attributes whatsoever:

/States/States/StateProvince[not(@territory)]
