PropertyKey PropertyValue
Size XXL
ProdTaxType 5%
FOR the same chile node name i am getting only one record from xml string. So, please suggest in above sp.

Answer 1

Because your XML is not formed well, it should be like this:
DECLARE #hdoc varchar(max) = '<XML>
<ProductDetail>
<Barcode>150604658</Barcode>
<PropertyDetail>
<PropertyKey>Size</PropertyKey>
<PropertyValue>XXL</PropertyValue>
</PropertyDetail>
<PropertyDetail>
<PropertyKey>ProdTaxType</PropertyKey>
<PropertyValue>5%</PropertyValue>
</PropertyDetail>
</ProductDetail>
</XML>'
In your example the PropertyDetail has duplicate attributes.
It could be also re-written like this:
DECLARE #hdoc varchar(max) = '<XML>
<ProductDetail Barcode="150604658">
<PropertyDetail PropertyKey="Size" PropertyValue="XXL" />
<PropertyDetail PropertyKey="ProdTaxType" PropertyValue="5%" />
</ProductDetail>
</XML>'
Now you would not think of writing:
<PropertyDetail PropertyKey="Size" PropertyValue="XXL"
PropertyKey="ProdTaxType" PropertyValue="5%" />
but the meaning is the same as the XML you have - and duplicate attributes are not allowed.
