> trying to inject following:
> public void insert(@XPath("concat('48','//node/msisdn/text())") String msisdn) { }
> results in  
> Can not convert #STRING to a NodeList! exception.
> The reason is that XPathAnnotationExpressionFactory uses 
> XPathBuilder.xpath(xpath); 
> and by default xpath is evaluated as nodeSet.
> I think it would be nice to be able to define result type in annotation e.g.
> @XPath(value = "concat('48','//node/msisdn/text())", resultType = String.class)
> The default would be NodeSet to be backward compatible
