利用XMLHTTP 从其他页面获取数据

  xml|数据|页面

我们在编写ASP代码的时候,大家都知道可以通过post或者get获得form表单的数据,那么我们如何直接获得其他页面上的数据呢?这就要借助xmlhttp协议了。xmlhttp是xmldom技术的一部分。

下面的代码就是一个很简单的例子,我们利用xmlhttp技术,把站点首页的代码以xml的形式完全获取,并且在页面中输出。

<%
  Dim objXMLHTTP, xml
  Set xml = Server.CreateObject("Microsoft.XMLHTTP")
 
  xml.Open "GET", "", False
  ' Pull the data from the web page
  xml.Send

  Response.write "Here's the html we now have in our xml object"
  Response.write "


"
  Response.Write "<xmp>"
  Response.Write xml.responseText
  Response.Write "</xmp>"
  Response.write "


"
 Response.write " Now here's how the page looks:

"
  Response.Write xml.responseText
 
  Set xml = Nothing
%>

下面是另一个实例

<%
dim objHTTP , objXML , objXSL
set objHTTP = Server.CreateObject("Microsoft.XMLHTTP")
objHTTP.open "GET", "", false
objHTTP.send
set objXML = objHTTP.responseXML
set objXSL=Server.CreateObject("microsoft.xmldom")
objXSL.async=false

objXSL.load(Server.MapPath("style.xsl"))

if (objXSL.parseError.errorCode = 0) then
    Response.Write(objXML.transformnode(objXSL))
else
    Response.Write "Error: " & objXSL.parseError.reason & " URL:" & objXSL.url
end if

Set objHTTP = Nothing
Set objXML = Nothing
Set objXSL = Nothing
%>

style.xsl:
<xsl:stylesheet xmlns:xsl="">
    <xsl:template match="/">
