I hope this will help when dealing with encoding issues with MSXML.
This is from
How to Encode XML Data
by Chris Lovett
I'll quote the pertinent part:
"To change the encoding that the XML DOM Save method uses, you need to
create an XML declaration with an encoding attribute at the top of your
document as follows:
var pi = xmldoc.createProcessingInstruction("xml",
" version='1.0' encoding='ISO-8859-1'");
When you call the save method, you will then get an ISO-8859-1 encoded file
<?xml version="1.0" encoding="ISO-8859-1"?>
Now, be careful you don't let the XML property confuse you. The XML property
returns a Unicode string. If you call the XML property on the DOMDocument
object after creating the ISO-8859-1 encoding declaration, you will get the
following Unicode string back:
Notice that the ISO-8859-1 encoding declaration is gone. This is normal. The
reason it did this is so that you can turn around and call LoadXML with this
string and it will work. If it does not do this, LoadXML will fail with the
error message: "Switch from current encoding to specified encoding not
I loaded up VB6 and referenced msxml2.dll
and slapped this code in a button.
Dim AccessLicXml As MSXML2.DOMDocument
Dim vCodePage As Variant
dim pi as Variant
vCodePage = "version='1.0' encoding='ISO-8859-1'"
Set AccessLicXml = New MSXML2.DOMDocument
Set pi = AccessLicXml.createProcessingInstruction("xml", vCodePage) '
' the save method writes this fragment out as it will appear
' when the document is saved
' <?xml version="1.0" encoding="ISO-8859-1"?>
MsgBox AccessLicXml.xml ' shows xml missing the encoding but it is stored
and output by the save 'method
