想不明白的PHP正则问题
【代码】
$str= HTML...




HTML...
EOD;

$reg1='/]*>(.(?!$reg2='/|[^>]+>)/s';
$reg3='/]*>(.(?!|[^>]+>)/s';

preg_match ($reg1,$str,$out1);
preg_match ($reg2,$str,$out2);
preg_match ($reg3,$str,$out3);

echo "$str\n\n\n

【问题】
正则表达式1、正则表达式2分别准确完整地匹配到目标字符串的前后两部分；
正则表达式3是正则表达式1、正则表达式2的整合，却出现了问题，匹配不到内容；
尝试了好久也找不出，正则表达式1、正则表达式2之间有什么冲突的地方？

我只有14分资源分，全部给了也就这么多了。
不知道哪位高手能指导一下？

$reg3='/]*>(.(?!|[^>]+>)/s';
