如何用VB提取网页源代码中的绘图app源码特定字符

       Dim HtmlData As String

        Dim Str1 As Long

        Dim Str2 As Long

        Dim wname As String

        dim ename as string

        Str1 = 1

        HtmlData = 已得到网页来源str

        Do Until Str1 = 0

        Str1 = InStr(Str1 + 1, HtmlData, "<span class='style5'>")

        Str2 = InStr(Str1 + 1, HtmlData, "</span>")

        If Str1 > 0 And Str2 > 0 And Str2 > Str1 Then

        wname = Mid(HtmlData, Str1, Str2 - Str1)

        wname = Replace(wname, "<span class='style5'>", "")

        wname = Replace(wname, "</span>", "")

        ename= ename & wname

        End If

        Loop
