I can't see any major problem with what you are doing, except possibly
for the specification of the parentNode for the revAppendXML command.
Try leaving out the /'s.

I would also recommend doing it in 2 stages: read the file into a
variable, then append the variable. e.g.

  put URL ("file:" & line x of tFiles) into tXMLdata
  revAppendXML targetXMLFile, "StudentURL_table", tXMLdata

I always surround the file stuff with brackets before using put or get
URL. It seems to be more reliable.

And after each XML command or function, check the result and see if it
contains "xmlerr".

HTH,
