[opencms-dev] How can make my own CmsXmlNav?[ path bar ]

[Salvador Santander]

I want to make a own CmsXmlNav to have a "page path bar", some like this:

If the getNavTree generate some like this:

Menu1
  SubMenu11
	SubMenu111
      SubMenu112
  SubMenu12
	SubMenu121 
	SubMenu122
Menu2
  SubMenu21

If i'm seeing theSubMenu121 page the "page path bar" that i want looks like

Menu1->SubMenu12->SubMenu121

Somebody has made it?

What could be a start point?

Thanks.
