<b>浅谈 ASP 模板技术之参数传递</b>(2)


      'Run the search against the content string we've been passed
         Set Matches = objRegEx.Execute(sContent)
      '循环已发现的匹配
         For Each Match in Matches
         'Replace each match with the appropriate HTML from our ParseTag function
         sContent = Replace(sContent, Match.Value, ParseTag(Match.Value))
         Next
      '消毁对象
         set Matches = nothing
         set objRegEx = nothing
      '返回值
         ProcessCustomTags = sContent
End Function

  在上面的代码中,用到了正则表达式,如果你对它还不是很了解,请参阅相关资料,这里就不详细介绍了。

那么怎么取出参数值呢,也是一个函数:代码拷贝框

复制代码 代码如下:

'【功能】取得模板标签的参数名
'如:<tag:loop channelid="1" pagesize="10" title="20" type="NEW" column="1">
function GetAttribute(ByVal strAttribute, ByVal strTag)
      Dim objRegEx, Matches
      '建立正则表达式
         Set objRegEx = New RegExp
      '查找内容 (the attribute name followed by double quotes etc) 
         objRegEx.Pattern = lCase(strAttribute) & "=""[0-9a-zA-Z]*"""
      '忽略大小写
         objRegEx.IgnoreCase = True
      '全局查找
         objRegEx.Global = True
      '执行搜索
         Set Matches = objRegEx.Execute(strTag)
      '如有匹配的则返回值, 不然返回空值
         if Matches.Count > 0 then
              GetAttribute = Split(Matches(0).Value,"""")(1)
         else
              GetAttribute = ""
         end if
      '消毁对象
         set Matches = nothing
         set objRegEx = nothing
end function
