lo puoi parsare con uina tua pagina asp

codice:
<%

dim strError, strURL
strURL = "http://www.donimioesterno.com/pagina.asp"

dim xmlDom, nodeCol, oNode, oChildNode
set xmlDom = Server.CreateObject("MSXML2.Domdocument")
xmlDOM.async = False

call xmlDom.setProperty("ServerHTTPRequest", true)
xmlDom.async = false
call xmlDom.load(strURL)

if not xmlDom.documentElement is nothing then
  
  set nodeCol = xmlDom.documentElement.selectNodes("channel/item")
  ii = 1
  Response.ContentType = ("text/xml" )
  Response.Write("<?xml version='1.0' encoding='iso-8859-1'?>")
  for each objNode in nodeCol
    Response.Write("<item>")'& vbCrLf)
    
    set oChildNode = objNode.selectSingleNode("pubDate")
    if not oChildNode is nothing then
  		strPubDate = Server.HTMLEncode(oChildNode.text)
  		'strPubDate = replace(strPubDate, "&apos;", "'")
  		'strPubDate = replace(strPubDate, "&amp;", "&")
  		'strPubDate = replace(strPubDate, vbCrLf, "
")
    '  Response.Write("" & strPubDate & "
" & vbCrLf)
    end if

    set oChildNode = objNode.selectSingleNode("link")
    if not oChildNode is nothing then
      Response.Write("<url>" & oChildNode.text & "</url>")
  	  strLink = "yes"
    end if

    set oChildNode = objNode.selectSingleNode("title")
    if not oChildNode is nothing then
  		strTitle = Server.HTMLEncode(oChildNode.text)
  		'strTitle = replace(strTitle, "&apos;", "'")
  		'strTitle = replace(strTitle, "&amp;", "&")
  		'strTitle = replace(strTitle, vbCrLf, "
")
      Response.Write("<title>" & strTitle & "</title>")
	  'Response.Write("<url>" & strLink & "</url>")
    end if

'  	if strLink = "yes" then
 '     Response.Write("</item>" )'& vbCrLf)
  '	end if

    ii = ii + 1
    Response.Write("</item>")' & vbCrLf)
