If you have the option (and the XML is a representative of the real XML)
change the input XML to:-

<DESC @ID="123">test123...</DESC>
<DESC @ID="456">test456...</DESC>

The xpath becomes:-

/root/B/DESC[@ID='456']

Good XML design would not associate elements the occur multiple times by
their position in relation to each other.  The whole point of having a
heiarchical structure is to be able to group related elements together under
a parent element.
