To find the different document nodes just use:


Remember that in a node-set all nodes have different identity (this is
exactly what "set" means)

Truly great madness cannot be achieved without significant intelligence.
To invent, you need a good imagination and a pile of junk
Never fight an inanimate object
To avoid situations in which you might make mistakes may be the
biggest mistake of all
Quality means doing it right when no one is looking.
You've achieved success in your field when you don't know whether what
you're doing is work or play
To achieve the impossible dream, try going to sleep.
Facts do not cease to exist because they are ignored.
Typing monkeys will write all Shakespeare's works in 200yrs.Will they
write all patents, too? :)
Sanity is madness put to good use.
I finally figured out the only reason to be alive is to enjoy it.
