//row

selects the the elements row in no namespace, which is 0.

You want the  elements row in the namespace
http://HesaValidateSqlSend

so that is

//h:row

where some ancestor element 9eg xsl:stylesheet0 has

xmlns:h="http://HesaValidateSqlSend"

In XPath1 you must always use a prefix to select a namespaced element.

You don't really want // eiether as it's rather expensive, it looks like
you want

/h:HesaValidate_Response/h:row
