Suppose I have this XML:
<x>
<e a='1' b='A'/>
<e a='1' b='B'/>
<e a='1' b='A'/>
</x>
I'd like to write an xpath to find any elements e which:
- Have attribute @b = 'A'
- Have the same value for attribute @a
The xpath can't reference the literal value of attribute @a, however. It can reference the literal value of attribute @b.
Or more generally, I want to find if there are any instances where there are two or more elements e[@b=A'] with the same value for attribute @a.
Is this possible?
