写了段批量抓取某个列表页的东东

有些人当抓取程序是个宝，到目前还TND有人在卖钱，强烈BS一下这些家伙真是的！可能偶下边这段东西比较烂哈
下边这个没有写入库功能，已经到这一步了，入库功能是很简单的事了，需要的请自己去完成吧，其它功能各位自行完善吧！把代码拷贝过去直接运行即可看到效果

Dim Url,List_PageCode,Array_ArticleID,i,ArticleID
Dim Content_PageCode,Content_TempCode
Dim Content_CategoryID,Content_CategoryName,BorderID,ClassID,BorderName,ClassName
Dim ArticleTitle,ArticleAuthor,ArticleFrom,ArticleContent

Url = "http://www.webasp.net/article/class/1.htm"
List_PageCode = getHTTPPage(Url)
List_PageCode = RegExpText(List_PageCode,"打印/th>/tr>","/table>table border=0 cellpadding=5",0)
List_PageCode = RegExpText(List_PageCode,"td align=left>a href='../","'>img border=0 src='../images/authortype0.gif'",1) '取得当前列表页的文章链接，以,分隔
Array_ArticleID = Split(List_PageCode,",") '创建数组，存储文章ID

For i=0 To Ubound(Array_ArticleID)-1
    ArticleID = Array_ArticleID(i)    '文章ID
    Content_PageCode = getHTTPPage("http://www.webasp.net/article/"ArticleID)    '取得文章页的内容

    '=========取文章分类及相关ID参数开始=======================
    Content_TempCode = RegExpText(Content_PageCode,"a href=""/article/"">技术教程/a> gt;gt; ","gt;gt; 内容/td>",0)
    Content_CategoryID = RegExpText(Content_PageCode,"a href='../class","/'>",1)
    BorderID = Split(Content_CategoryID,",")(0)    '大类ID
    ClassID = Split(Content_CategoryID,",")(1)    '子类ID
        '==========检查大类是否存在开始===============
        '如果不存在则入库

        '==========检查大类是否存在结束===============
    'Response.Write(BorderID "," ClassID "br />")
    Content_CategoryName = RegExpText(Content_PageCode,"/'>","/a>",1)
    BorderName = Split(Content_CategoryName,",")(0)    '大类名称
    ClassName = Split(Content_CategoryName,",")(1)    '子类名称
        '==========检查子类是否存在开始===============
        '如果不存在则入库

        '==========检查子类是否存在结束===============
    '=========取文章分类及相关ID参数结束=======================

    '=========取文章标题及内容开始=============================
    ArticleTitle = RegExpText(Content_PageCode,"tr>td align=center bgcolor=#DEE2F5>strong>","/strong>/td>/tr>",0)
    ArticleAuthor = RegExpText(Content_PageCode,"tr>td>span class=blue>作者：/span>","/td>/tr>",0)
    ArticleFrom = RegExpText(Content_PageCode,"tr>td>span class=blue>来源：/span>","/td>/tr>",0)
    ArticleContent = RegExpText(Content_PageCode,"tr>td class=content style=""WORD-WRAP: break-word"" id=zoom>","/td>/tr>"VBCrlf"        /table>"VBCrlf"    /td>/tr>/table>",0)
    '=========取文章标题及内容结束=============================
    Response.Write(ArticleTitle "br />br />")
    Response.Flush()
Next

附几个函数：

Function getHTTPPage(url)
    IF(IsObjInstalled("Microsoft.XMLHTTP") = False)THEN
        Response.Write "br>br>服务器不支持Microsoft.XMLHTTP组件"
        Err.Clear
        Response.End
    END IF
    On Error Resume Next
    Dim http
    SET http=Server.CreateObject("Msxml2.XMLHTTP")
    Http.open "GET",url,False
    Http.send()
    IF(Http.readystate>4)THEN
        Exit Function
    END IF
    getHTTPPage=BytesToBSTR(Http.responseBody,"GB2312")
    SET http=NOTHING
    IF(Err.number>0)THEN
        Response.Write "br>br>获取文件内容出错"
        'Response.End
        Err.Clear
    END IF
End Function

Function BytesToBstr(CodeBody,CodeSet)
    Dim objStream
    SET objStream = Server.CreateObject("adodb.stream")
    objStream.Type = 1
    objStream.Mode =3
    objStream.Open
    objStream.Write CodeBody
    objStream.Position = 0
    objStream.Type = 2
    objStream.Charset = CodeSet
    BytesToBstr = objStream.ReadText
    objStream.Close
    SET objStream = NOTHING
End Function

End Function
