问个正则表达式 很简单ubb标签的

Question

插入表情的时候 在文本框显示 [em15] 请问用正则怎么匹配
在后台替换成 <img  src="/img/mood/15.gif" border="0" />
另外在编辑的时候 又如何把数据<img  src="/img/mood/15.gif" border="0" /> 替换成[em15]
需要两个版本 一个是js 一个是.net
由于对正则不熟 请帮忙下 谢谢

Answer 1

替换 [em15]            string source = "xxxx[em15]xxxxx[em15]xxxxxx";
            string replacestr = @"<img src=""/img/mood/15.gif"" border=""0"" />";
            Regex reg = new Regex(@"\[em15\]");
            source = reg.Replace(source, replacestr);替换成<img            string source = @"xxxx<img src=""/img/mood/15.gif"" border=""0"" />xxxxx<img src=""/img/mood/15.gif"" border=""0"" />xxxxxx";
            string replacestr = @"[em15]";
            Regex reg = new Regex(@"<img[^>].*?15.gif.*?/>");
            source = reg.Replace(source, replacestr);根据实际情况调试一下吧

        string str = "xxxx[em11]xxxxx[em12]xxx[em15]xxx";
        string result = Regex.Replace(str, @"\[em(\d+)\]", @"<img src=""/img/mood/$1.gif"" border=""0"" />");
        Response.Write(result);
/*
xxxx<img src="/img/mood/11.gif" border="0" />xxxxx<img src="/img/mood/12.gif" border="0" />xxx<img src="/img/mood/15.gif" border="0" />xxx

    var reg = /<img[^>]*?src=\"\/img\/mood\/(\d+)\.gif\"[^>]*?>/ig;
    var result = str.replace(reg,"[em$1]");
    document.write(result);
