WXFULLDATA.XML -problems in extracting datas

Hello !

thanks for reply.
Can you please send me here in a message a very simple source in ajax to extract data from xml page in WD ?
For example source to extract TEMP or DATE from page : http://poschiavo.no-ip.org:8080/wdfulldata.xml
Then I can use it for all parameters just changing the type of data
Thanks a lot !
