采用asp遍历XML文档 [英] Traverse XML document using asp

问题描述

我试图找到，如果某个元素是一个XML文件present，如果是，将其删除。不过，我不断收到此错误：

I'm trying to find if a certain element is present in a XML file and if it is, remove it. However I keep getting this error:

Description: Type mismatch: 'NodeList'

我的code是这样的：

My code looks like this:

<%@ Language=VbScript%>
<%

Dim address

Set xmlDoc = CreateObject("Microsoft.XMLDOM")
xmlDoc.async = False
xmlDoc.load (Server.MapPath("XML/sensor.xml"))

Set Root = XMLDoc.documentElement 

Set NodeList = Root.getElementsByTagName("sensor")

For Each i In NodeList

    if ((NodeList(i).getElementsByTagName("Address")(0).childNodes(0).nodeValue)=request.form("remove_address")) then
    NodeList.parentNode.removeChild NodeList 
    End if
Next



NodeList.parentNode.removeChild NodeList 
xmlDoc.Save "\www./XML/sensores.xml"

Response.Redirect("remove_sensor_modbus.html")

%>

和XML文件是这样的：

And the XML file looks like this:

<?xml version="1.0"?>
<sensors>
<sensor>
    <Address>40000</Address>
</sensor>
<sensor>
    <Address>46999</Address>
</sensor>
</sensors>

的形式是填充了这个相同的XML文件中的下拉菜单。
有谁知道这可能是造成这个错误？

The form is a dropdown menu populated with this same XML file. Does anyone knows what could be causing this error?

推荐答案

它看起来像你有你的循环几个错误。试试这个：

It looks like you have several errors in your loop. Try this:

Dim removeAddress
Set removeAddress = Request.Form("remove_address")

For Each sensorNode In NodeList
    Dim addressNode
    Set addressNode = sensorNode.GetElementsByTagName("Address")(0)

    If (addressNode.Text = removeAddress) Then
        sensorNode.RemoveChild(addressNode)
    End if
Next
