如何将一行中某个关键特征的单次筛选出来，断行放到另一个文件中？

xinglu1983

file:
<thing text="111" x="yyy" text="222" z="aaaa" />
temp:
<thing src="111">
<thing src="222">

RT如何由file得到temp？
谢谢~

1. $ echo '<thing text="111" x="yyy" text="222" z="aaaa" />' | grep -oP '(?<=text=).+?"' | sed 's/^/<thing src=/;s/$/>/'
   
2. <thing src="111">
   
3. <thing src="222">
