This is true -- you're trying to obtain the union of a node-set with a number ...

I guess (again) that you want to conditionally specify two different numeric values.
However, in your original source xml "Holding" were empty elements!

Therefore I changed them to contain numbers like this:

<ROOT>
<HoldingInformation2Response>
	<Items>
		<Item>
			<Holding>1200</Holding>
			<class_code>OMN</class_code>
			<Available/>
		</Item>
		<Item>
			<Holding>800</Holding>
			<class_code>DRP</class_code>
			<Available/>
		</Item>
	</Items>
</HoldingInformation2Response>
<RetrieveClassInfoRSResponse>
	<Items>
		<Item>
			<ClassCode>OMN</ClassCode>
			<DisplayOnInternetSite>N</DisplayOnInternetSite>
		</Item>
	</Items>
	<Items>
		<Item>
			<ClassCode>DRP</ClassCode>
			<DisplayOnInternetSite>Y</DisplayOnInternetSite>
		</Item>
	</Items>
</RetrieveClassInfoRSResponse>
</ROOT>

In case my guess is right, then here's an example how this can be done (decide for
yourself whether this is really "tidying up" :o) ):


/ROOT/HoldingInformation2Response/Items/Item[1]/Holding 
* number(/ROOT/HoldingInformation2Response/Items/Item[1]/class_code != 'OMN') 

+

/ROOT/HoldingInformation2Response/Items/Item[1]/Holding 
* number(/ROOT/HoldingInformation2Response/Items/Item[1]/class_code = 'OMN') div 100

This will return 12.

/ROOT/HoldingInformation2Response/Items/Item[2]/Holding 
* number(/ROOT/HoldingInformation2Response/Items/Item[2]/class_code != 'OMN') 

+

/ROOT/HoldingInformation2Response/Items/Item[2]/Holding *
number(/ROOT/HoldingInformation2Response/Items/Item[2]/class_code = 'OMN') div 100

This will return 800


Hope this helped.
