将一对标志符之间的多行合并成一行

yelang5460

想将下面的文本中<>之间的部分的多行数据格式化成这样的一行行数据，以方便后期查找替换...
<favorite launcher:packageName="com.android.browser" launcher:className="com.android.browser.BrowserActivity" launcher:screen="3" />

<favorite之前可能有多个空格或者tab ，<favorite然后后面还可能有回车 空格或者换行

1. sed '/<[^>]\+$/{:a;N;/>/!ba;s/\n//g}'

复制代码

骑着蜗牛定乾坤

BEGIN {FS="\n" RS="" ORS=""} 类似这样的分割方法，将每一段看作一个记录，而将每一段中的每一条字符串看作一个字段

骑着蜗牛定乾坤

可否详细解释一下，尤其｛｝内的语法回复 2# stupid_lee

感谢楼上各位大神

sed的语法还是比较好理解的

awk简直没法说，看了几篇基础文章，来理解这个简直一头雾水.....

论坛里的对于awk的高级用法的讲解 貌似相关文章不多啊 哪位大神翻译一点造福一下大家么......

感谢，这行代码基本实现了我的要求

只是结果没有替换多个空格为一个空格  然后各行之间会有一个空行

sed完全可以做到，强....

只是我这边跑出来的结果出现一个问题

有些行之间出现了一行到两行的空行

可能是回车符没替换掉


这行sed代码还是很赞的  .....
