I have a server computer with Windows 2008, IIS7 and Sharepoint. I have ASP page inside Sharepoint. I want to read XML file. I have find nice manuals on the internet how to do it. My problem is, that after i put first line of the code i get error message (unknown error).

for example this working: <%Response.Write(now())%>

BUT THIS NOT WORKING: <%Set objXML = Server.CreateObject("Microsoft.XMLDOM")%>

What i tryed:
1.Istalled msxml3.msi (msxml3.dll)
2.Installed XMLinst.exe
3.change object type to Msxml2.DOMDocument.3.0 from Microsoft.XMLDOM

i getting the same error message. Can anybody help me what is missing from my system or how to make it work????  
this should be the full code:
 
 
 <%
 Set objXML = Server.CreateObject("Microsoft.XMLDOM")
 Set objLst = Server.CreateObject("Microsoft.XMLDOM")
 Set objHdl = Server.CreateObject("Microsoft.XMLDOM")
 
 objXML.async = False
 objXML.Load (Server.MapPath("linx.xml"))
 
 Set objLst = objXML.getElementsByTagName("mainmenu")
 
 menuitemcount = objLst.length
%>
 
<h1>Testurl:<h1>
 
 <%
 For i = 0 To (menuitemcount  1)
 
  Set objHdl = objLst.item(i)
 
  Response.Write("<a href=""" & _
                  objHdl.childNodes(1).childNodes(0).text & _
                  """>" & objHdl.childNodes(0).text & _
                  "</a><br>")
 
 Next
 %>

Try
Set objXML = CreateObject("MSXML2.DOMDocument")

Or by Version
Set objXML = CreateObject("MSXML2.DOMDocument.3.0")
Set objXML = CreateObject("MSXML2.DOMDocument.4.0")
Set objXML = CreateObject("MSXML2.DOMDocument.6.0")

Also you do not need the lines:
Set objLst = Server.CreateObject("Microsoft.XMLDOM")
Set objHdl = Server.CreateObject("Microsoft.XMLDOM")

You should remove them espacially because you are not destroying these objects before creating new ones with
Set objLst = objXML.getElementsByTagName("mainmenu")
Set objHdl = objLst.item(i)

Best practice als would be to destroy each object (Set objABC = Nothing) before creating a new one even if it is the same object variable! Example:

For i = 1 To 3
  Set objABC = objItem(i)
  Response.Write objABC.Text
  Set objABC = Nothing
Next

Dim objXML, objLst, objHdl
Set objXML = Server.CreateObject("Microsoft.XMLDOM")
 
objXML.async = False
objXML.Load(Server.MapPath("linx.xml"))
 
Set objLst = objXML.getElementsByTagName("mainmenu")
menuitemcount = objLst.length
%>
 
<h1>Testurl:<h1>
 
 <%
 For i = 0 To (menuitemcount - 1)
 
  Set objHdl = objLst.item(i)
 
  Response.Write("<a href=""" & _
                  objHdl.childNodes(1).childNodes(0).text & _
                  """>" & objHdl.childNodes(0).text & _

Please provide details of the sharepoint error; prt. screen if no other info is available
You don't have to reinstall anything in IIS

Other aspect, where is that ASP page hosted? The corresponding app pool for that site is the same as for the sharepoint site?

it is inside sharepoint

sharepoint address: http://merkur/_layouts/plautwelcome/pwelcome.aspx
physical address: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\plautwelcome\pwelcome.aspx

without that code the page is working correctly.

you'll have to host the page on a diff. site (URL with a dif. hostheader/port) and include it in sharepoint using a Page Viewer WebPart

You are using ASP Classic Code in a ASP.NET application? That can not work.

Rename file to .asp instead of .aspx or recode to ASP.NET!

Maybe you also have to activate ASP 3.0 in order to run classic ASP and .asp extension.

You have to add this as role of the server in server-manager under control panel.
