Const BLOCKTAGLIST As String = ";APPLET;EMBED;FRAMESET;HEAD;NOFRAMES;NOSCRIPT;OBJECT;SCRIPT;STYLE;"
Dim nPos1 As Integer
Dim nPos2 As Integer
Dim nPos3 As Integer
Dim strResult As String
Dim strTagName As String
Dim bRemove As Boolean
Dim bSearchForBlock As Boolean
nPos1 = InStr(strText, "<")
Do While nPos1 > 0
nPos2 = InStr(nPos1 + 1, strText, ">")
If nPos2 > 0 Then
strTagName = Mid(strText, nPos1 + 1, nPos2 - nPos1 - 1)
strTagName = Replace(Replace(strTagName, vbCr, " "), vbLf, " ")
nPos3 = InStr(strTagName, " ")
If nPos3 > 0 Then
strTagName = Left(strTagName, nPos3 - 1)
End If
If Left(strTagName, 1) = "/" Then
strTagName = Mid(strTagName, 2)
bSearchForBlock = False
Else
bSearchForBlock = True
End If
If InStr(1, TAGLIST, ";" & strTagName & ";", vbTextCompare) > 0 Then
bRemove = True
If bSearchForBlock Then
If InStr(1, BLOCKTAGLIST, ";" & strTagName & ";", vbTextCompare) > 0 Then
nPos2 = Len(strText)
nPos3 = InStr(nPos1 + 1, strText, "" & strTagName, vbTextCompare)
If nPos3 > 0 Then
nPos3 = InStr(nPos3 + 1, strText, ">")
End If
If nPos3 > 0 Then
nPos2 = nPos3
End If
End If
End If
Else
bRemove = False
End If
If bRemove Then
strResult = strResult & Left(strText, nPos1 - 1)
strText = Mid(strText, nPos2 + 1)
Else
strResult = strResult & Left(strText, nPos1)
strText = Mid(strText, nPos1 + 1)
End If
Else
strResult = strResult & strText
strText = ""
End If
nPos1 = InStr(strText, "<")
Loop
strResult = strResult & strText
RemoveHTML = strResult
End Function
