Invalid Character when exporting to XML

[trifectabx]

Hello,
I'm a newbie at this.. I tried exporting a table to XML and receiving an error " An Invalid Character was found in text content". I found this VBA function from the net and I've created my function and I created a Module. But how do I run this in Access to search for the invalid characters. My table is called LOG. Here's what I created for the module.

FUNCTION CLEAN(dirtyStr)
DIM cleanStr AS String
dim charValue as intger

FOR i = 1 TO LEN(dirtyStr)
let charValue = ASC(MID(dirtyStr,i,1))
if charValue>=32 and charValue <=126 then
cleanStr=cleanStr + MID(dirtyStr,i,1)
endif
NEXT i

let CLEAN=cleanStr
END FUNCTION

Use the function in your query like:
select clean(fldXL) from tblLOG
