It's rather complicated. This is not what PropTree was built for, as far 
as I can see - support for multiple nodes with the same name is rather 
weak. Path resolution always takes the first that comes up. It's not an 
XPath engine - not by far.
The steps to take in this specific case would be:
1) Get the child "rss.channel".
2) Call sort() on the channel. (Marcin, is sort() stable, i.e. would it 
preserve the relative order of the item elements here?)
3) Use std::equal_range() with "item" to get the start and end iterator 
of the item elements.
4) For each of the items, get the child "title".
