Steps to Reproduce Behavior

1. Create the large XML document about 100 MB in size by following these steps:
   1. In Microsoft Visual Basic, create a new Standard EXE project. Form1 is created by default.
   2. Add a Command button to Form1. Command1 is created by default.
   3. Paste the following code into the Click event for Command1:

      On Error GoTo handler
      Open "c:\inetpub\wwwroot\big.xml" For Output As #1
      Print #1, "<?xml version=""1.0"" ?>"
      Print #1, "<XML>"
      Dim i As Long
      For i = 1 To 100000
         Print #1, "<t>" & String(1000, "o") & "</t>"
      Next i
      Print #1, "</XML>"
      Close #1
      Exit Sub
      handler:
        MsgBox Err.Number & ":" & Err.Description, vbExclamation, Err.Source
      						

   4. Create the test VBScript file: Paste the following code into the new text file:
      To run the code with MSXML 4.0 parser, change:

      Set saxReader = CreateObject("Msxml2.SAXXMLReader.3.0")

      To

      Set saxReader = CreateObject("Msxml2.SAXXMLReader.4.0")
   5. Press the F5 key to run the project from Visual Basic.
      
      NOTE:The program creates a file of about 100 MB in size. The program takes quite a while to run. Be sure that you have sufficient free hard disk drive space. Be sure to delete the XML file after you complete the test below.
2. Create the test VBScript file:
   1. Using Windows Notepad or another text editor, create a new text file.
   2. Paste the following code into the new text file:

      dim saxReader
      Set saxReader = CreateObject("Msxml2.SAXXMLReader.3.0")
      saxReader.putFeature "server-http-request", true
      saxReader.parseURL "http://localhost/big.xml"
      WScript.Echo "Done! saxReader.parseURL"
      						

   3. Save the text file as C:\Big.VBS.
3. Open Windows NT Performance Monitor to monitor memory usage:
   1. In Microsoft Windows NT or Microsoft Windows 2000, press the CTRL+ALT+DEL keypad combination.
   2. On the dialog box that is displayed, select Task Manager.
   3. In Task Manager, click the Performance tab, and note the graph of Memory Usage History.
   4. Size and position Performance Monitor so that you can see the Memory Usage History but still work on the Windows Desktop.
4. Test:
   1. On the Windows Start menu, select Run.
   2. In the Run dialog box, type the following command:

      wscript c:\big.vbs

   3. Click OK, and note memory usage in Performance Monitor.
