分享正则表达式匹配问题
我想匹配html中的script代码，文档中可能有多个script，我想取得期中含有特定内容的一个怎么办,如
<acript>代码1</script>dfsdsdfsddfdsfsd黄航
fsdfsadfs
hjfghfg
jhgfjhghj
换行
<script>
代码2
换行
指定内容
代码3
</script>dsdsd换行
换行
换行
sdfsdsd
dfsd
换行
sdsfd
<script>
代码4
换行
指定内容
代码5
</script>
都有若干换行，我想要我想要加红色标记的那一对script标记中的内容，利用“指定内容”
<acript>代码1</script>dfsdsdfsddfdsfsd黄航

hjfghfg
jhgfjhghj
换行

我理解的正则就是找到相同或者不相同的地方进行匹配。
好像不太好找。我的思路树下。
1你要找的代码没有中文字符
2用分组找
