如何使用xmlstarlet附加多个子节点的xml文件？

Question

我想在</audio_selector>

之后添加此块

<input_clipping>
<end_timecode>00:00:05:00</end_timecode>        
 <order>1</order>
 <order>2</order>   
<start_timecode>00:00:01:00</start_timecode>        
</input_clipping>

以下是我的预期输出：

这是我尝试过的。

        xmlstarlet edit -L \
        --update "//job/input/file_input/uri" \
        --value 'my_source' \
        --update "//job/output_group/file_group_settings/destination/uri" \
        --value 'my_destination'
        --append "//job/input//audio_selector" \
        --type elem --name 'input_clipping' --value '' 
        --append "//job/input/input_clipping" \
        --type elem --name 'end_timecode' --value '0:00:05:00' 
        --append "//job/input/end_timecode" \
        --type elem --name 'order' --value '1' 
        --type elem --name 'order' --value '2'            
        --append "//job/input//audio_selector" \
        --type elem --name "start_timecode" --value "0:00:01:00" file.xml

我可以知道缩短它并让它运行的正确方法是什么？

非常感谢。

xmlstarlet 解决方案：

将要附加的标记保存到文件subnode.xml（只是样本名称）中：

<input_clipping>
<end_timecode>00:00:05:00</end_timecode>        
 <order>1</order>
 <order>2</order>   
<start_timecode>00:00:01:00</start_timecode>        
</input_clipping>

工作：

xmlstarlet ed -a "//job/input/audio_selector" -t elem -n input_clipping \
-v "$(xmlstarlet sel -t -c '//input_clipping/*' subnode.xml)" file.xml \
| xmlstarlet unesc
