Re: Nested list, from flat to structure

I have this input-XML:

<lnum1>list 1 A</lnum1>
<lp1>list 1 A paragraph</lp1>
<lnum1>list 1 B</lnum1>
<lnum2>list 2 A</lnum2>
<lnum2>list 2 B</lnum2>
<lp2>list 2 paragraph</lp2>
<lnum2>list 2 C</lnum2>
<lnum1>list 1 C</lnum1>

And I want this output:

<list
	<point>
		<p>list 1 A</p>
		<p>list 1 A paragraph</p>
	</point>
	<point>
		<p>list 1 B</p>
		<list>
			<point>
				<p>list 2 A</p>
			</point>
			<point>
				<p>list 2 B</p>
				<p>list 2 paragraph</p>
			</point>
			<point>
				<p>list 2 C</p>
			</point>
		</list>
	</point>
	<point>
		<p>list 1 C</p>
	</point>
</list>

I've tried many different approches. I did come up with a solution for
all the elements starting with 'lnum', it worked well, but the elements
with 'lp' did confuse me. Anyone with an advice or solution?
