Reading xml data using classic ASP

问题

I have written a code for reading xml data in classic asp as follows:

<%


 Dim objxml
    Set objxml = Server.CreateObject("Microsoft.XMLDOM")
    objxml.async = False
    objxml.load ("/abc.in/xml.xml")



set ElemProperty = objxml.getElementsByTagName("Product")
set ElemEN = objxml.getElementsByTagName("Product/ProductCode")
set Elemtown = objxml.getElementsByTagName("Product/ProductName")
set Elemprovince = objxml.getElementsByTagName("Product/ProductPrice")  

Response.Write(ElemProperty)
Response.Write(ElemEN) 
Response.Write(Elemprovince)
For i=0 To (ElemProperty.length -1) 

    Response.Write " ProductCode = " 
    Response.Write(ElemEN) 
    Response.Write " ProductName = " 
    Response.Write(Elemtown) & "<br>"
    Response.Write " ProductPrice = " 
    Response.Write(Elemprovince) & "<br>"

next

Set objxml = Nothing 
%>

This code is not giving proper output. Please help me out.

The xml is:

<Product>
   <ProductCode>abc</ProductCode>
   <ProductName>CC Skye Hinge Bracelet Cuff with Buckle in Black</ProductName>
</Product>

Try this:

<%   

Set objXMLDoc = Server.CreateObject("MSXML2.DOMDocument.3.0")    
objXMLDoc.async = False    
objXMLDoc.load Server.MapPath("/abc.in/xml.xml")

Dim xmlProduct       
For Each xmlProduct In objXMLDoc.documentElement.selectNodes("Product")
     Dim productCode : productCode = xmlProduct.selectSingleNode("ProductCode").text   
     Dim productName : productName = xmlProduct.selectSingleNode("ProductName").text   
     Response.Write Server.HTMLEncode(productCode) & " "
     Response.Write Server.HTMLEncode(productName) & "<br>"   
Next   

%>

Notes:

Don't use Microsoft.XMLDOM use the explicit MSXML2.DOMDocument.3.0
Use Server.MapPath to resolve virtual paths
Use selectNodes and selectSingleNode instead ofgetElementsByTagName. The getElementsByTagName scans all descendants so can return unexpected results and then you always need to index into the results even though you know you expect only one return value.
Always Server.HTMLEncode data when sending to the response.
Don't put ( ) in weird places, this is VBScript not JScript.

Here an example how to read your data, given the xml is

<Products>
  <Product> 
    <ProductCode>abc</ProductCode> 
    <ProductName>CC Skye Hinge Bracelet Cuff with Buckle in Black</ProductName> 
  </Product>
  <Product> 
    <ProductCode>dfg</ProductCode> 
    <ProductName>another product</ProductName></Product>
</Products>

The following script

<%

Set objXMLDoc = Server.CreateObject("Microsoft.XMLDOM") 
objXMLDoc.async = False 
objXMLDoc.load("xml.xml") 

Set Root = objXMLDoc.documentElement
Set NodeList = Root.getElementsByTagName("Product")

For i = 0 to NodeList.length -1
  Set ProductCode = objXMLDoc.getElementsByTagName("ProductCode")(i)
  Set ProductName = objXMLDoc.getElementsByTagName("ProductName")(i)
  Response.Write ProductCode.text & " " & ProductName.text & "<br>"
Next

Set objXMLDoc = Nothing

%>

gives

abc CC Skye Hinge Bracelet Cuff with Buckle in Black
dfg another product
