XOM API for Processing XML with Java

[Christophe Marchand <christophe.marchand AT axyus.com>]

Hi !

Element.query("count(//document[@imported])"); throws this exception :
nu.xom.XPathTypeException: XPath expression count(//document[@imported]) 
returned a java.lang.Double instead of a node-set.
        at nu.xom.JaxenConnector.selectNodes(Unknown Source)
        at nu.xom.Node.query(Unknown Source)
        at nu.xom.Node.query(Unknown Source)

Is there a workaround, or should I use
Element.query("count(//document[@imported])").size() instead ?

Which workaround for avg(...) functions ?

Thanks in advance,
Christophe
