再帮我写个正则吧！

查找
包含<fmt:message，并且key中的词有“-”连接的单词。
如：
<fmt:message key="page-user-name"/>

<fmt:message key="data-user-sample"/>

<fmt:message key="a-b-c">
</fmt:message>

[amani11]

//还是php的
$str	= '<fmt:message key="page-user-name"/>

<fmt:message key="data-user-sample"/>

<fmt:message key="a-b-c">
</fmt:message>';

preg_match_all("/key=\"(.*?)\"/is",$str,$out);
print_r($out);
//打印出Array ( [0] => Array ( [0] => key="page-user-name" [1] => key="data-user-sample" [2] => key="a-b-c" ) [1] => Array ( [0] => page-user-name [1] => data-user-sample [2] => a-b-c ) ) 
//能符合么

<script>
var str = '<fmt:message key="page-user-name"/>'

			+'<fmt:message key="a-b-c">'
			+'</fmt:message>';
var re = /<fmt:message key="([^"]*-[^"]*)"(\/)?>/g;
var arr = str.match(re).join().replace(re,"$1");
alert(arr)
</script>

我的错了，

[shan1119]

[code=HTML]<div id=div1>
<fmt:message key="page-user-name"/>

<fmt:message key="data-user-sample"/>

<fmt:message key="a-b-c">
</fmt:message>
</div>
<script>
var str = div1.innerHTML;
str = str.match(/(?:\<fmt\:message key=\")[a-z]+(-[a-z]+)+/gi).join(",").replace(/\<fmt\:message key=\"/gi,"");;
alert(str);
</script>

[/code]

[lemon520]

var re = /<fmt:message key="([\w-]+)"/g
alert(txt.match(re).join().replace(re, $1));

<fmt:message(?![^->]*>)[^>]+>

[兔子-顾问]

<script type="text/javascript"> 
var test = "<fmt:message key=\"page-user-name\"/>";
var reg = /<fmt:message key=\"(?![^-\"]*\")[^"]+"/ig;
document.write(test.match(reg));
</script>

[foolbirdflyfirst]

接分。

var setting = '<fmt:message key="page-user-name"/>' //匹配
			 +'<fmt:message key="-datause-rsample"/>' //不匹配
			 +'<fmt:message key="a-b-c"></fmt:message>'//匹配
			 +'<fmt:message key="a-b-"></fmt:message>'//不匹配
			 +'<fmt:message key="a---b---c"></fmt:message>'//不匹配
			 +'<fmt:message key=\'a-b-c\'/>';//匹配

var pat = new RegExp("<fmt\\s*:\\s*message\\s+key\\s*=\\s*([\'\"])[a-z]+(-[a-z]+)+\\1[^>]*(?:(?:\/>)|(?:>[^<>]*</fmt\\s*:\\s*message>))",'ig');

[foolbirdflyfirst]

贴漏了，

alert(setting.match(pat));
