报错:XML页无法显示,下列标记没有被关闭解决方法

从数据库读出数据，然后以XML的格式显示数据，但是提示hd,category,subsort等没有关闭，可是我已经关闭了呀,不知道具体是什么原因造成了这个问题？
VB code:


代码如下:

<%
response.ContentType= "text/xml"
Response.CharSet = "GB2312"
Response.Expires = 0
Response.write "<?xml version=""1.0"" encoding=""UTF-8"" ?>"
Response.write vbcrlf&"<hd>"
Response.write vbcrlf&vbTab&"<category>"
Response.write vbcrlf&vbTab&vbTab&"<subsort>"
‘连接数据库的语句省略
do while not rs.eof
response.write vbcrlf&vbTab&vbTab&vbTab&"<item>"
response.write vbcrlf&vbTab&vbTab&vbTab&vbTab&"<id>"&rs("id")&"</id>"
response.write vbcrlf&vbTab&vbTab&vbTab&"</item>"
loop
rs.close()
set rs=nothing
response.write vbcrlf&vbTab&vbTab&"</subsort>"
response.write vbcrlf&vbTab&"</category>"
response.write vbcrlf&"</hd>"
Response.End()
%>

因为输出的内容不能带<>”‘&这几个特殊字符，需要进行XmlEncode编码，如下的代码详情：
VBScript code:


代码如下:

Function XMLEncode(var)
On Error Resume Next
Dim strTmp
If (IsNull(var)) Then
var = ""
End If
If (VarType(var) = 11) Then
If (var) Then
strTmp = "1"
Else
strTmp = "0"
End If
Else
strTmp = CStr(var)
strTmp = Replace(strTmp, "&", "&")
strTmp = Replace(strTmp, "<", "<")
strTmp = Replace(strTmp, ">", ">")
strTmp = Replace(strTmp, """", """)
strTmp = Replace(strTmp, "'", "'")
End If
XMLEncode = strTmp
End Function
Function XMLDecode(str)
Dim temp
temp=replace(str,"&","&")
temp=replace(temp,"<","<")
temp=replace(temp,">",">")
temp=replace(temp,""","""")
temp=replace(temp,"'","'")
XMLDecode = temp
End Function
Response.Write XmlEndode(rs("字段名字"))

另外，如果是文件编码问题，则可以将:
Response.write “<?xml version=”"1.0″” encoding=”"UTF-8″” ?>”
改成
Response.write “<?xml version=”"1.0″” encoding=”"GB2312″” ?>”
另外，在开始输出之前，需要清空内容:
Response.Clear
Response.write “<?xml version=”"1.0″” encoding=”"GB2312″” ?>”
另外，写成:
Response.write vbCrlf & vbTab & vbTab & “<subsort>”
更容易观察.
