求嵌套循环正则表达式

yoory 2013-02-27 02:18:40

目标文本是：

123456
{loop name="loop1" data=$arcrs}
{loop:arclist name="loop3" param1= param2=}
{loop name="loop3" data=$arc}
{/loop}
123456
{/loop:arclist}
{/loop}

123456789

{loop name="loop1" data=$arcrs}
{loop:arclist name="loop3" param1= param2=}
{loop name="loop3" data=$arc}
{/loop}
{/loop:arclist}
{/loop}

需要匹配出成里面的{loop}标签

匹配出来应该是2个记录：

记录1：

{loop name="loop1" data=$arcrs}
{loop:arclist name="loop3" param1= param2=}
{loop name="loop3" data=$arc}
{/loop}
123456
{/loop:arclist}
{/loop}

记录2：

{loop name="loop1" data=$arcrs}
{loop:arclist name="loop3" param1= param2=}
{loop name="loop3" data=$arc}
{/loop}
{/loop:arclist}
{/loop}
