When using the command:

-bash-4.2$ xmlstarlet ed -u "/configurations/rules/rule/branch" -v 'DAVID' config.xml > final.xml

I see that the output file was changed to DAVID, But it was changed globally every place the tag "branch" was declared.

But I only want to change it on one subnode, let's say "APP1", What is the command that I need to use? and is there a way to give the value 'DAVID' as a parameter?

 </rule>
 </rules>
 </configurations> 

xmlstarlet solution:

new_branch="DAVID"
xmlstarlet ed -u "/configurations/rules/rule[name='APP1']/branch" -v "$new_branch" config.xml > final.xml

The crucial <rule> node should look like:

<rule>
 <name>APP1</name>
 <repo>hookTester</repo>
 <branch>DAVID</branch>
 <emailTo>test@gmail.com</emailTo>
 <path>F1/ido.xml </path>
 </rule>

You are also able to modify the initial file inplace by applying global -L option:

xmlstarlet ed -L -u ... config.xml
