How to use FILTERXML to have all the mapped items of an XML source?

Hi,
when I use FILTERXML I obtain only the first result.

Look in example at:

=FILTERXML(WEBSERVICE(“http://www.ansa.it/sito/ansait_rss.xml"),"//item/description”)

How to obtain all mapped items?

Thank you

Select OK will produce:
