在shell中从xml中提取值 [英] Extract value from xml in shell

问题描述

我必须遵循 xml 结构:

I have to following xml structure:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE DOC SYSTEM "ts.dtd">
<?xml-stylesheet type="text/css" href="ts.css"?>
<DOC LOCALE="en-US"> 
   <PTXT ID="some.first.id" CONTEXT="">Some text 1</PTXT> 
   <PTXT ID="some.second.id" CONTEXT="">Some text 2</PTXT> 
</DOC>

现在我的挑战是在每个 PTXT 标签上循环并使用 ID 和内部文本做一些事情.出于示例目的，我们只是说我需要回显类似

Now my challenge is to loop on every PTXT tag and do something with the ID and the inner text. For example purposes, let's just say that I need to echo something like

some.first.id Some text 1
some.second.id Some text 2

如何在 shell 脚本中使用它?

How can I have that in a shell script?
