怎样撰写一个过虑掉HTML编码的涵数?

<%
Function Filterhtml(strToFilter)
  Dim strTemp
  strTemp = strToFilter
  While Instr(1,strTemp,"<") AND Instr(1, strTemp, ">")
    strTemp = Left(strTemp, Instr(1, strTemp, "<")-1) & Right(strTemp, Len(strTemp)-Instr(1,strTemp, ">"))
  WEnd
  Filterhtml = strTemp
End Function
%>
