Returns the instrument ID of the single equity underlyer.

The XPath query which can also be passed to the FpMLGenericQuery() function to generate the same result is : //descendant::equityOption/underlyer[1]/singleUnderlyer[1]/equity[1]/instrumentId/text(). This function requires the input of a FpMLDoc object key, which must have been produced via a call to the ReadFpML() function.

This function would have returned a string 'KEY' which is to be passed to the 'FpMLDocKey' parameter of this function.

If you were looking at the FpML document, a typical example of walking to this(these) node(s) would be...

  // FpML Document -> equityOption

    -> underlyer[1]

      -> singleUnderlyer[1]

        -> equity[1]

          -> instrumentId

            -> return( nodeValue(s) )

Or if using the FpMLGenericQuery() function...

//descendant::equityOption/underlyer[1]/singleUnderlyer[1]/equity[1]/instrumentId/text()
