XML Tree

programming

I’m new to XML and want to create a stylesheet to hide the tags in the following XML Document Tree:


<t1 title="&#160;Chapter 1">
     <o> Idea1</o>
     <t2 title="&#160;Chapter 2">
          <o>Idea2</o>
     </t2>
</t1>

How can I do so? Also, how can I make trees appear at the same level?

All advice is welcome.
