A co-worker of mine found the answer this morning on MS support site:

   http://support.microsoft.com/default.aspx?scid=kb;en-us;315719

Note that we *are* using MSXML 4.

Here's a snipped from that page:

SUMMARY
MSXML includes two functions that you can use to filter data in a
case-insensitive search. With MSXML 3.0, you can use the translate
function. With MSXML 4.0, you can use either the translate function or
the new ms:string-compare XPath function. 

oXML.setProperty "SelectionLanguage", "XPath"
set node = oXML.selectSingleNode("Domains/DomainName[translate(.,
'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') =
'mydomain1.com']")
---------------------------------------------------------
So, going with the "translate" approach, all we had to do was add this
line:

     oXML.setProperty "SelectionLanguage", "XPath"

and then our translate worked fine.

Thanks for the input.

This error indicates that you are not using DOMDocument40 but, rather,
an earlier version (DOMDocument30 pssibly) which uses Microsoft's old
XSL language (by default) rather than the standard XSL language.

Sorry for the top post - thank Groupwise :(

I can't get 'translate' to work - this code (and many other similar
versions):

--------------------------------
    Dim a
    a =
"applications/application/acronym[translate(.,'ABCDEFGHIJKLMNOPQRSTUVWXY
Z','abcdefghijklmnopqrstuvwxyz')='"
& LCase(sNodeText) & "']"
   oDupNodes = Session("Applications").selectNodes(a)

-------------------------------

produces this ASP error:

Unknown method.
applications/application/acronym[-->translate(.<--,'ABCDEFGHIJKLMNOPQRST
UVWXYZ','abcdefghijklmnopqrstuvwxyz')='asap']


Any ideas?  Notice that it doesn't seem to like the 'translate'
function.

TIA.
