Re: [xsl] Recursively traversing an outline with level gaps

[Dimitre Novatchev <dnovatchev@xxxxxxxxx>]

It seems to me that the additional xml file is not necessary, neither
recursive processing is needed.

Just output the values of every <p> element.

Or is there something that I'm getting wrong?
