XMLReader is useful when you want configuration settings read from a  
config.xml file to your own structures.
Creating XML from your structures towards a libxml tree can be done  
using the tree API (or the writer)

Partial settings can be dumped by selecting the right node (start  
point for your partial data) and write that part to a file. (or memory)

Should not be too much of an issue (except when you are doing things  
on very low memory based hardware)

I would suggest the xmlReader if you need these config settings used  
in your software.
You can keep the configuration by using xmlTextReaderCurrentDoc() to  
manipulate and store it at a later time by using the raw tree API.

See: http://xmlsoft.org/examples/testWriter.c
I did not do anything with writer (yet) but it seems a nice and easy  
way to create the configuration XML from scratch. As soon as you have  
an existing configuration XML, the tree API might be more useful.
