xmlstarlet replace xml node value

Question

I'm new using xmlstarlet. I'd like to know how to change the value of xml node using xmlstarlet.

I tried something.

xmlstarlet ed --inplace -u '/file_input/uri'  'string("s3://my_source")' template.xml > output.xml

doesn't work.

My expected output as <uri>s3://my_source</uri> and <uri>s3://mydestination</uri>. I'd like to change source_path and destination_path node.

<?xml version="1.0" encoding="UTF-8"?>
<job version="2.10.8">
    <input>
        <deblock_enable>Auto</deblock_enable>
        <deblock_strength>0</deblock_strength>
        <no_psi>false</no_psi>
        <order>1</order>
        <timecode_source>zerobased</timecode_source>
        <file_input>
            <certificate_file nil="true"/>
            <password>upass</password>
            <uri>source_path</uri>
            <username>uname</username>
        </file_input>
        <file_group_settings>
            <rollover_interval nil="true"/>
            <destination>
                <password>upass</password>
                <username>uname</username>
                <uri>destination_path</uri>
            </destination>
        </file_group_settings>
    </input>
</job>

Thank you very much.

With xmlstarlet:

xmlstarlet edit \
           --update "//job/input/file_input/uri" \
           --value  's3://my_source' \
           --update "//job/input/file_group_settings/destination/uri" \
           --value  's3://mydestination' file.xml

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