>OK. Are you trying to append the XML file to the end of the string (represented in stringbuilder)....or are you trying to insert it in a specific location within the existing string?

The goal is to be able to use a VFP StrTran() equivalent which is case insensitive. So, I have about 142k of XML data that I need to lookup for about 120 fields to see if they are in it. If yes, I need to replace them with the record values.
