xmlstarlet append and insert new line value

Question

I\'d like to know how to add a new line using xmlstarlet.

My aim is to add a after job/input/file_input/uri.

Answer 1

I suggest to append (--append) after the desired node/element a new element (--type elem) with name audio (--name "audio") and value (--value "track_01"):

xmlstarlet edit \
           --update "//job/input/file_input/uri" \
           --value 's3://my_source' \
           --update "//job/input/file_group_settings/destination/uri" \
           --value 's3://mydestination' \
           --append "//job/input/file_input/uri" \
           --type elem --name "audio" --value "track_01" file.xml

If you want to edit file.xml inplace, add option -L.
