How to insert subnode in xml file using xmlstarlet or any other bash command?

I have multiple xml files where i want to update a subnode if the subnode project points to different project or insert a subnode if it doesn't exist using a xmlstarlet or any other command that can be used in a bash script.

I have been able to update the subnode project if it doesn't point to the right project using xml starlet command, but i am not able to insert subnode project if the project tag doesn't exist.

I have tried.

Code:
xmlstarlet ed -P --update "///module[@id='pxc110237_1']/@project" -v"X1" --insert"///module[@id='pxc110237_1']/@project --type attr -n style -v"X1" file.xml

The file looks like:
Code:
 <?xml version="1.0"?>
  <kgcontent>
    <containers>
       <module project="ANY" level="1" id="pxc110233_1"/>
       <module project="X1" level="1" id="pxc110234_1"/>
       <module id="pxc110235_1"/>
    </containers>
  <kgcontent>

I want the output to look like:
Code:
<?xml version="1.0"?>
  <kgcontent>
    <containers>
       <module project="ANY" level="1" id="pxc110233_1"/>
       <module project="X1" level="1" id="pxc110234_1"/>
       <module project="X1" id="pxc110235_1"/>
    </containers>
  <kgcontent>

The starlet command i used doesn't have any effect on the file. how can i fix the above problem? any pointers would be great help Smilie

NAME
cdde.xml - Configuration file for cdde DESCRIPTION
When cdde is run for the first time, an example xml configuration file (~/.cdde.xml) is created for you: <?xml version="1.0"?> <cdde delay="5000000"> <drive path="/dev/cdrom"> <audio command="echo An audio cd was inserted."/> <data command="echo A data cd was inserted."/> <dvd command="echo A dvd was inserted."/> <vcd command="echo A vcd was inserted."/> <svcd command="echo A svcd was inserted."/> <blank command="echo A blank cdr/dvdr was inserted."/> <mixed command="echo A mixed (audio/data) cd was inserted."/> </drive> </cdde> This default file is not very useful, and so I suggest you to edit it to your needs before running cdde again. You may add as many drive entries, or commands as you like. If multiple entries are found for a type of disc then all entries will be run in the order they are found. The specific device in use can be passed to the command with one of the following special tags: %dev% - is replaced with the device name of the cdrom that just had a disc inserted %mnt% - is replaced with the listed mount point for the cdrom that just had a disc inserted Note: %mnt% is determined through your fstab (usually located in /etc) file. If you do not have a listing for each <drive> in the fstab this will cause problems. This way, you can tell your video player which device to use when playing a VCD, for example. EXAMPLE
This is an example of ~/.cdde.xml file: <?xml version="1.0"?> <cdde delay="5000000"> <drive path="/dev/cdroms/cdrom0"/> <audio command="xmms %mnt%"/> <data command="mount %mnt%"/> <dvd command="xterm -iconic -e mplayer -fs -xineramascreen 1 -dvd 1"/> <vcd command="xterm -iconic -e mplayer -fs -xineramascreen 1 -vcd 1"/> <svcd command="xterm -iconic -e mplayer -fs -xineramascreen 1 -vcd 1"/> <blank command="gcombust"/> <mixed command="mount %mnt%"/> </drive> </cdde> FILES
