Replace attribute on xml via command line

I was looking this question xmlstarlet update an attribute and trying to replace an attribute inside a Jboss configuration file. I post here just a little part of the xml:

<?xml version='1.0' encoding='UTF-8'?>

<server xmlns="urn:jboss:domain:10.0">
    <extensions>
        <extension module="org.jboss.as.clustering.infinispan"/>
    </extensions>
    <system-properties>
        <property name="hibernate.hbm2ddl.auto" value="validate"/>
    </system-properties>
</server>

What i would like to replace is the value of hibernate.hbm2ddl.auto from validate to update

Following the previous answer i tried this command, but dont update the value:

xmlstarlet edit   --update "//property[@name='hibernate.hbm2ddl.auto']/@value"   --value "update" conf.xml

I tried to follow the full path, but the result is the same: no update.

xmlstarlet edit   --update "/server/system-properties/property[@name='hibernate.hbm2ddl.auto']/@value"   --value "update" conf.xml
Solution

  • Your file uses namespaces (xmlns="urn:jboss:domain:10.0").

    xmlstarlet edit --update '//*[local-name()="property"][@name="hibernate.hbm2ddl.auto"]/@value' -v "update" conf.xml

    I used //*[local-name()="property"] to bypass all namespaces in conf.xml
