比如说我要在163中统计"网易"在这个页面出现的次数..
这个可以统计么??
要怎么统计才可以啊??
谢谢~~~
可以的,你可以使用正则表达式的贪婪模式搜索出同一字符串出现的次数。
<%
'常用函数
'1、输入url目标网页地址,返回值getHTTPPage是目标网页的html代码
function getHTTPPage(url)
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 err.Clear
end function
'2、转换乱玛,直接用xmlhttp调用有中文字符的网页得到的将是乱玛,可以通过adodb.stream组件进行转换
Function BytesToBstr(body,Cset)
dim objstream
set objstream = Server.CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = Cset
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
'匹配字符串
Function GetNum(ByVal Content)
Dim objRegEx, Match, Matches,i
i=0
Set objRegEx = New RegExp
objRegEx.Pattern = "网易"
objRegEx.IgnoreCase = True
objRegEx.Global = True
objRegEx.MultiLine = True
Set Matches = objRegEx.Execute(Content)
PContent=""
For Each Match in Matches
i=i+1
Next
Response.Write i
set Matches = nothing
set objRegEx = nothing
End Function
Dim Url,Html
Url="http://www.163.com"
Call GetNum(getHTTPPage(Url))
%>
