xml - 在经典 ASP 中对 XML 数据进行排序

Question

我想在xml下面排序，基于成人和 child (我需要把成人和 child 作为常数):

<HotelDetails>
  <hotel>
    <rooms>
      <room>
        <roomname>Single</roomname> 
        <Price>100</Price> 
        <Adult>1</Adult> 
        <child>0</child> 
      </room>
    </rooms>
    <rooms>
      <room>
        <roomname>Single</roomname> 
        <Price>150</Price> 
        <Adult>1</Adult> 
        <child>0</child> 
      </room>
    </rooms>
    <rooms>
      <room>
        <roomname>Double</roomname> 
        <Price>200</Price> 
        <Adult>2</Adult> 
        <child>1</child> 
      </room>
    </rooms>   
  </hotel>
</HotelDetails>

给:

Hotel :   Single-100,Double-200,Total 300Single-150,Double-200,Total 350

I try to sort with below code, but it comes like constant (distinct data). Anyone have an idea to sort above XML use something like below code?

<%@ Language="VBScript" CodePage="65001"%>  
<%  
Response.ContentType = "text/plain; charset=UTF-8"  

Dim doc   
Set doc = Server.CreateObject("Msxml2.DOMDocument.3.0") 
doc.async = False  

If doc.load(Server.MapPath("ee.xml")) Then   
  doc.setProperty "SelectionLanguage", "XPath"

  Dim xpath
  xpath = "HotelDetails/hotel/rooms[not(room/Adult= preceding-sibling::rooms/room/Adult)]/room/Adult"

  For Each Adult in doc.selectNodes(xpath) 
    Response.Write "Hotel" & VbCrLf
    Response.Write Adult.ChildNodes.Item(0).Text & VbCrLf  
  Next
Else   
  Response.Write doc.parseError.reason   
End If 
%>  

我怎样才能做到这一点？

另一种可能性是使用 ADODB 断开连接记录集，并使用 ADODB 工具进行排序和提取。

一个很好的起点(代码在 VB 中):

How To Obtain an ADO Recordset from XML

Dim oStream As ADODB.Stream
Set oStream = New ADODB.Stream

oStream.Open
oStream.WriteText sXML   'Give the XML string to the ADO Stream

oStream.Position = 0    'Set the stream position to the start

Dim oRecordset As ADODB.Recordset
Set oRecordset = New ADODB.Recordset

oRecordset.Open oStream    'Open a recordset from the stream

oStream.Close
Set oStream = Nothing

Set RecordsetFromXMLString = oRecordset  'Return the recordset

Set oRecordset = Nothing
