Trying to add an element to existing xml file with xmlstarlet

I've been trying to get xmlstarlet to add <security-enabled>false</security-enabled> to "/configuration/core". The command runs without error, but now changes are made to the file.

The XML file:

<configuration xmlns="urn:activemq" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:activemq /schema/artemis-configuration.xsd">
  <jms xmlns="urn:activemq:jms">
    <queue name="DLQ"/>
    <queue name="ExpiryQueue"/>
  </jms>
  <core xmlns="urn:activemq:core">
    <!-- this could be ASYNCIO or NIO
       -->
    <journal-type>ASYNCIO</journal-type>
    <paging-directory>./data/paging</paging-directory>
    <bindings-directory>./data/bindings</bindings-directory>
    <journal-directory>./data/journal</journal-directory>
    <large-messages-directory>./data/large-messages</large-messages-directory>
    <journal-min-files>10</journal-min-files>
    ...
  </core>
</configuration>

One of the commands I have run:

xmlstarlet ed -i "/configuration/core" -t attr -n "security-enabled" -v "false"  broker.xml

I have also used xmlstarlet ed -L ... to edit in place, but when I noticed the edits weren't happening I dropped -L for STDOUT.

You need to specify xml namespace properly. In your case:

xmlstarlet ed -L -N a="urn:activemq" -N c="urn:activemq:core" -s "/a:configuration/c:core" -t elem -n "security-enabled" -v "false" broker.xml

Moreover I changed:

  • -t attr to -t elem since we need element instead of attribute
  • -i to -s since we are asking for sub element to be added
