What could be the easiest way to check if a certain username exists?
I have an xml like this:

<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>

When it comes to check if a certain user with a certain username exists, I
don know an easy way to do that. Can someone help? Thnx.
