Boost property tree: Remove a node

Question

How would you remove a node from boost xml property tree?

I have a document like this:

<folders>
  <folder>some/folder</folder>
  <folder>some/folder</folder>
  <folder>some/folder</folder>
</folders>

I know how to itereate and print all folders, but how would i remove one of the items and save the xml back?

Answer 1

I would probably try:

boost::property_tree::ptree pt;

pt.erase(key);
