How ASP reads XML data files

Save the following two pieces of code separately, One save for readxml.asp another save as Test.xml, placed under the same directory, debugger can, in the program I have explained, read the code can be made into a readxml function, by using the input parameters to read XML different data records of different values. This program is adapted from the internet, what is the discrepancy please forgive me.

Readxml.asp

以下是引用片段：
<%
dim xml,objNode,objAtr,nCntChd,nCntAtr
Set xml=Server.CreateObject("Microsoft.XMLDOM")
xml.Async=False
xml.Load(Server.MapPath("test.xml"))
Set objNode=xml.documentElement
nCntChd=objNode.ChildNodes.length-1
'这个可以定义asp读取xml文件的那一个值，通过传递这个值来确定读取的数据
for i=0 to nCntChd
set objAtr=objNode.ChildNodes.item(i)
nCntAtr=objAtr.Attributes.length-1
'历遍一条记录里面的所有的记录项，记录是从0开始的
for j=0 to nCntAtr
response.write objAtr.Attributes.item(j).Text&"<br>"
next
response.write "<br>"
next
Set objAtr=Nothing
Set objNode=Nothing
Set xml=Nothing
%>

Test.xml

<?xml version="1.0" encoding="utf-8" ?>

A brief description of the objects and methods of the DOM:

The DocumentElement property confirms the root (root) node of the XML file.

selectSingleNode returns the first node that conforms to the style.

The Loadxml method loads a fragment of an XML file or string.

HasChildNodes method if the specified node has one or more child nodes, the return value is true.

The CreateElement method creates an element with the specified name.

The AppendChild method plus a node is treated as the last child node of the specified node.

The Createcdatasection method creates a CDATA that contains specific data.
