Take the following, schematic html-code:
<div>
<span id='1' cust-attr='' />
<span id='2' />
<span id='3' cust-attr='Foo' />
</div>
Now I am looking for a selector finding all span
s which either do not have an attribute "cust-attr" or whose "cust-attr" value is empty.
In this case, this would be the 1 and 2.
I tried the following selectors with the following results:
span[cust-attr!=]
selects 2 and 3span[cust-attr='']
only selects 1span:not([cust-attr])
selects 2span(:not([cust-attr]),[cust-attr=''])
selects all threespan([cust-attr=''],:not([cust-attr]))
selects 1
However, I did not find one selecting only 1 and 2.
Do you know a possibility?
Note that I want to avoid:
span:not([cust-attr]),span[cust-attr='']
as "span" is in reality a more complex expression.

Late to the party...
... or you could use CSS Selectors and be 10x as fast as both jQuery answers... :)
