leggere nodi e valori di un xml

[aledg]

Ciao a tutti

sto usando questo codice per leggere l'xml del servizio yahoo.weather

<%
Set objXML = Server.CreateObject("Microsoft.XMLDOM")
objXML.setProperty "ServerHTTPRequest", true 
objXML.async = False

strFile= "http://weather.yahooapis.com/forecastrss?w=718345&u=c"
objXML.Load (strFile)

Set AllItems = objXML.selectNodes("//channel")

For I = 0 to (AllItems.Length - 1)
  Set Post = AllItems(I).selectNodes("item")
  For J = 0 to (Post.Length-1)
      Set title = Post(J).selectNodes("title")
      Set description = Post(J).selectNodes("description")
      Set ywea=Post(J).selectNodes("yweather:condition")
%>
<%=title(0).text%>

<%=description(0).text%>

<%=ywea(0).text%>

<%
  Next
    Set title = Nothing
    Set description = Nothing
    Set link = Nothing
    Set Post = Nothing
Next
%>

riesco a leggere il file e non mi restituisce nessun errore solo che il nodo yweather:condition non mi visualizza niente, io vorrey stampare a video il valore di "code" e di "temp" per esempio


<yweather:condition text="Mostly Cloudy" code="28" temp="50"...


questo è tutto l'output xml completo

in pratica penso di riuscire a selezionare il nodo ma poi non so come dirgli che voglio leggere il valore di "code" e di "temp"

ragazzi ho risolto se dovesse servire a qualcuno per leggere gli attributi di un nodo si fa così:

<%=ywea(0).getAttribute("code")%>

nel mio caso il nodo si chiama yweather:condition e leggo l'attributo code ecco il codice completo:

<%

Set objXML = Server.CreateObject("Microsoft.XMLDOM")
objXML.setProperty "ServerHTTPRequest", true 

objXML.async = False
strFile= "http://weather.yahooapis.com/forecastrss?w=718345&u=c"
objXML.Load (strFile)

Set AllItems = objXML.selectNodes("//channel")

For I = 0 to (AllItems.Length - 1)
  Set Post = AllItems(I).selectNodes("item")
  For J = 0 to (Post.Length-1)

         Set ywea=Post(J).selectNodes("yweather:condition")

%>
Code:<%=ywea(0).getAttribute("code")%>

Temp:<%=ywea(0).getAttribute("temp")%>

Text:<%=ywea(0).getAttribute("text")%>

<%
  Next
    Set title = Nothing
    Set description = Nothing
    Set link = Nothing
    Set Post = Nothing
Next
%>
