研究了两天搞出以下代码，共享给各个同行，我只贴过程函数出来，百度是网上找来的，其实其他三个也有代码，只是对应的网页代码改了，数据抓取不对，我重写了这三个函数，尤其是alexa罗索....

sub GoogleRank(strurl,id)

reg.IgnoreCase=true

str_bottom="</font>"
reg.Pattern=""&str_top&"((.|/n)*?)"&str_bottom&""
Set matches = reg.execute(str1)
str1=""
For Each match1 in matches
str1=match1.value
Next
Set matches = Nothing
Set reg = Nothing
str1=replace(replace(str1,str_top,""),str_bottom,"")
conn.execute("update webtable set pr='"&str1&"' where id="&id)
end sub
