ASP如何获得代码中第一张图片地址


把pattern 又修改了下

  'code要检测的代码

  'http://www.knowsky.com/asp.asp

  'leixing html 或者ubb

  'nopic 代码没有图片时默认值

function toppic(code,leixing,nopic)
    set regex = new regexp
    regex.ignorecase = true
    regex.global = true
    if leixing = "html" then
        regex.pattern = "<img(.*?)srcs?=s?(u0022?)([^u0022/>]+)"
    else
        regex.pattern = "[img]([^u005B]+)“
    end if
    set matches = regex.execute(code)
    if regex.test(code) then
                 if leixing = "html" then
              toppic = matches(0).submatches(3)
                 else
                      toppic = matches(0).submatches(0)
                 end if
    else
        toppic = nopic
    end if
end function
code1 = "<img src=""1.gif"">"
pic = toppic(code1,"html","nopic.gif")
response.Write pic
