现在网页的广告越来越多了，有时候想是不是干脆把页面转换为纯文本显示是不是更好一些，看了看GREENBROWSE的一些插件，感觉用JAVASCRIPT或者VBSCRIPT的正则REGEX应该可以实现，浏览的时候看到一篇文章：http://www.codeproject.com/asp/removehtml.asp

里面写了很多方法，最后是VBSCRIPT脚本的，我就复制下来想试一试，放到VB里面，

Option Explicit
Public Function RemoveHTML(strText As String) As String
    Dim TAGLIST
    TAGLIST = ";!–;!DOCTYPE;A;ACRONYM;ADDRESS;APPLET;AREA;B;BASE;BASEFONT;" & _
              "BGSOUND;BIG;BLOCKQUOTE;BODY;BR;BUTTON;CAPTION;CENTER;CITE;CODE;" & _
              "COL;COLGROUP;COMMENT;DD;DEL;DFN;DIR;DIV;DL;DT;EM;EMBED;FIELDSET;" & _
              "FONT;FORM;FRAME;FRAMESET;HEAD;H1;H2;H3;H4;H5;H6;HR;HTML;I;IFRAME;IMG;" & _
              "INPUT;INS;ISINDEX;KBD;LABEL;LAYER;LAGEND;LI;LINK;LISTING;MAP;MARQUEE;" & _
              "MENU;META;NOBR;NOFRAMES;NOSCRIPT;OBJECT;OL;OPTION;P;PARAM;PLAINTEXT;" & _
              "PRE;Q;S;SAMP;SCRIPT;SELECT;SMALL;SPAN;STRIKE;STRONG;STYLE;SUB;SUP;" & _
              "TABLE;TBODY;TD;TEXTAREA;TFOOT;TH;THEAD;TITLE;TR;TT;U;UL;VAR;WBR;XMP;"

    Const BLOCKTAGLIST = ";APPLET;EMBED;FRAMESET;HEAD;NOFRAMES;NOSCRIPT;OBJECT;SCRIPT;STYLE;"
   
    Dim nPos1
    Dim nPos2
    Dim nPos3
    Dim strResult
    Dim strTagName
    Dim bRemove
    Dim bSearchForBlock
   
    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

幸好还没有写别的什么，刚刚编译生成一个可执行文件，结果MCAFEE就报告：

2005-8-19 22:15:13 已移动（清除失败，因为文件不可清除）  时候\\Administrator LINK.EXE C:\\Documents and Settings\\Administrator\\桌面\\工程1.exe W32/Stup.worm (病毒)

真是被打败～～～～ 再想想，如果用脚本的话，还是需要所有的页面下载完成后才能解析，也没有什么意义，并且显示效果也不知道如何。

MCAFEE又是我必备的杀毒软件，算了～
