Strippe HTML
Jeg har prøvet med nedenstående function, og den virker for så vidt fint.
Men den fjerner ikke
<script language="JavaScript">
bla bla
</script>
PS. Jeg er helt ny med regExp.
Function stripHTML(strHTML)
'Strips the HTML tags from strHTML
Dim objRegExp, strOutput
Set objRegExp = New Regexp
objRegExp.IgnoreCase = True
objRegExp.Global = True
objRegExp.Pattern = "<(.|\n)+?>"
'Replace all HTML tag matches with the empty string
strOutput = objRegExp.Replace(strHTML, "")
'Replace all < and > with < and >
strOutput = Replace(strOutput, "<", " ")
strOutput = Replace(strOutput, ">", " ")
stripHTML = strOutput 'Return the value of strOutput
Set objRegExp = Nothing
End Function

Function RemoveHTML( strInputText )

End Function
