Re: Selecting the first node set

Given the following simplified XML instance, can anyone suggest an expression that will return ONLY the 'Value' node containing <enum> children with values A, B and C. I can't rely on the name of the parent node of <Value> hence I have deliberately named these as UnknownNameX or any other intervening structure.

<Trade>
<UnknownName1>
<Value>
<enum>A</enum>
<enum>B</enum>
<enum>C</enum>
</Value>
</UnknownName1>
<UnknownName2>
<Value>/Trade//Value[ancestor::Trade]</Value>
</UnknownName2>
<Treatment>
<UnknownName3>
<Value>
<enum>D</enum>
<enum>E</enum>
<enum>F</enum>
</Value>
</UnknownName3>
</Treatment>
</Trade>

/Trade//Value - returns all 3 <Value> nodes

/Trade//Value[1] - also returns all 3 <Value> nodes (why is that ?)

/Trade//Value[2] - returns nothing (why is that ?)

Cheers
