select xml element from web.xml using xmlstarlet

I'm using xmlstarlet to select values from web.xml. It is not working and returns nothing. If my web.xml contains following properties:

<web-app version="2.4"
   xmlns="java.sun.com/xml/ns/j2ee"
   xmlns:xsi="w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="java.sun.com/xml/ns/j2ee java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

command I'm executing 

xml select -t -v "web-app/display-name" web.xml

How can i ignore above ?

Solution

  • I used the following and succeeded

    xml sel -N x="http://java.sun.com/xml/ns/j2ee" -t  -v "x:web-app/x:security-role" /root/WEB-INF/web.xml
