Question

<textarea name="textarea1">
：<LOOP1  ChannelID=1111 Count=15 TitleLength=200>
<td><LOOP2 ChannelID=20390 Count=20 TitleLength=100>123456</Loop2></Loop1>
<LOOP1  ChannelID=2222 Count=16 TitleLength=300>
<td><LOOP2 ChannelID=20333 Count=20 TitleLength=100>654321</Loop2></Loop1>
</textarea>
<script language=javascript>
var str=document.getElementById("textarea1").value
re=/<loop1\s[^>]+>([\s\S](?!(<loop1)))+<\/loop1>/ig
a=str.match(re)
for(var i=0;i<a.length;i++)
{
alert(a[i])
}

Answer 2

用非贪婪式匹配：<SCRIPT LANGUAGE="JavaScript">
<!--
var s = "<LOOP1  ChannelID=1111 Count=15 TitleLength=200><td><LOOP2 ChannelID=20390 Count=20 TitleLength=100>123456</Loop2></Loop1><LOOP1  ChannelID=2222 Count=16 TitleLength=300><td><LOOP2 ChannelID=20333 Count=20 TitleLength=100>654321</Loop2></Loop1>";
var r = /<loop1\s[^>]+>[\s\S]+?<\/loop1>/gi;  //这个与你的正则只是多了一个 ? 而已
var a = s.match(r);
alert(a[0]);
alert(a[1]);
//-->
</SCRIPT>
