android - Read each of elements in XML file when clicking on an item in popup menu -


i have xml file below:

<?xml version="1.0" encoding="utf-8"?> <engine>    <engine1 engine1="engine1">     <cylinder cylinder="cylinder1" bp="0.01" p="0.02" t="0.04" ></cylinder>     <cylinder cylinder="cylinder2" bp="0.01" p="0.02" t="0.04" ></cylinder>     <cylinder cylinder="cylinder3" bp="0.01" p="0.02" t="0.04" ></cylinder>    </engine1>    <engine2 engine2="engine2">     <cylinder cylinder="cylinder1" bp="0.01" p="0.02" t="0.04" ></cylinder>     <cylinder cylinder="cylinder2" bp="0.01" p="0.02" t="0.04" ></cylinder>     <cylinder cylinder="cylinder3" bp="0.01" p="0.02" t="0.04" ></cylinder>    </engine2>  </engine>

i'm intending create popup menu presented list of engines (i.e. engine 1, engine 2,etc.). when clicking on 1 of engines in popup menu, shows specifications related engine in xml file (i.e. click on engine 1 in menu popup, specifications related engine 1 showed, corresponding other engines).

i have used menus represent popup menu. however, i don't know how read each of engine in xml file when click on "engine" in popup menu. tried use "switch-case" this, not successful because our number of engine , cylinder dynamic (not static 3 engines).

can guys me this? thank guys much!
