> For some slightly complex XPath queries, when using the RowIterator, the method Row.getPath() currently throws an exception. Example:
> {code}
> //hello[@x=1]/*[@y=1]
> {code}
> The problem is that this XPath query is converted to a SQL-2 query with more than one selector. When calling Row.getPath(), the method doesn't know which selector should be used.
> When using the NodeIterator (using getNodes), there is a workaround in the code (a "TODO"), but it is rather ugly. 
> Instead of using this workaround, it would be better to check the select column list, and if there is only one selector (which is the case for XPath queries), use that one.
