Question

<IMG src="/upload/201109//20110920085025872.jpg" border=0><IMG src="/upload/201109//20110920085033930.jpg" border=0>
<IMG src="/upload/201109//20110920085042691.jpg" border=0>
<IMG src="/upload/201109//20110920085052818.jpg" border=0>

Answer 1

var img=document.getElementsByTagName("img");
for(var i=0;i<img.length;i++){
var goal=img[i].getAttribute("src");
var reg=/\/upload\/201109\/\d+\.jpg/;
//可以根据需求设置你的正则表达式。
if(goal.test(reg)){
//do something you want.
}
}

Answer 2

^<IMG (.*) >$
img的大小写有关
如果是最后有/的例如：
<IMG src="/upload/201109//20110920085025872.jpg" border=0 />
用^<IMG (.*) \/>$匹配

Answer 3

<IMG src="(.*?)" border=0>

Answer 4

正则 /^(<IMG)[\s\w\=\"\/\.]+(border=0>)$/gm本回答被提问者采纳
