vb中怎么抓取网页中的特定信息

Question

比如我要抓google中的信息
我先在google中输入"xx"
把返回的所有的数据中，取数据中域名
比如返回如下格式：事实恒等式
http://www.xxx.com/dddd.asp?....我要取www.xxx.com
请教如何取这样的值之前有参考过这个代码

但是好象要抓google的比较的难
不太一样，很多垃圾信息！
请大侠帮下忙！

Answer 1

在vb程序中用浏览器控件上网搜索或者自己用http协议与网站通讯，传回来的网站信息你随便处理，都是字符串。。

Answer 2

Sub Getall()
Dim x() As String, i As Long, j As Long, url As String
url = "http://www.google.cn/search?num=100&q=" & InputBox("Please enter something to search:", "Info", "china")
With CreateObject("Msxml2.XMLHTTP")
For j = 0 To 5
.Open "GET", url & "&start=" & j * 100, False
.Send
x = Filter(Filter(Split(.responseText, "</a></nobr></div>"), "<br><span class=a>www."), ".com/ -")
For i = 0 To UBound(x)
x(i) = Replace(Replace("www." & Split(Split(x(i), "<br><span class=a>www.")(1), ".com/ -")(0) & ".com", "<b>", ""), "</b>", "")
If Not x(i) Like "*.*.*.*" Then Debug.Print x(i)
Next
Next
End With
End Sub代码返回：www.china.com
