Hi James.

Also, how can I tell what version is installed?

You may have several versions installed but this is an entirely different issue from which version of the dll will be used when you instantiate the dom < s >. If you use the old syntax like this:

oParser = CREATEOBJECT( 'Microsoft.XmlDom' )

It is going to use MSXML.DLL not matter what else is installed on your system. If you use the version independent progid, like this:

oParser = CREATEOBJECT( 'MsXml2.DomDocument' )

you'll have to take a look at the registry to be sure which version of MSXML is being used. On my system, if I look up the different clsids under HKCR\CLSID, this is what I get:

clsid                                  ProgID                dll
{2933BF90-7B36-11d2-B20E-00C04F983E60} MicroSoft.XmlDom       MsXml.dll
{F6D90F11-9C73-11D3-B32E-00C04F990BB4} MsXml2.DomDocument     MsXml3.dll
{f5078f1B-c551-11d3-89b9-0000f81fe221} MsXml2.DomDocument.2.6 MsXml2.dll
{f5078f32-c551-11d3-89b9-0000f81fe221} MsXml2.DomDocument.3.0 MsXml3.dll
{88d969c0-f192-11d4-a65f-0040963251e5} MsXml2.DomDocument.4.0 MxXml4.dll
