How should the used xsl be made, so as to have an exact search and replace? for example, LOGITECH Labs is an undesired replacement. We wanted to replace only each element that has exactly the word creative (case insensitive replacement), and not this word, wherever it may be found in the MANUFACTURER element

I think the error might be caused by elements containing more than one search term, here is an adapted code sample that hopefully does not give that error:
