Merge & Include

[Epsola]

I'm looking at loading many smaller configuration xml files and combining them.

1. Is there a way that I can merge nodes from two documents into one, so that afterward I can read config from just the one document?

e.g
Document 1

<node>
    <childUniqueA/>
    <childC/>
</node>

Document 2

<node>
    <childUniqueB/>
    <childC/>
</node>

Result

<node>
    <childUniqueA/>
    <childUniqueB/>
    <childC/>
    <childC/> <!-- duplicate entry from doc 2 is inserted after the same entry of doc 1 -- >
</node>

2. Does pugixml have any pre-processor directives to include other xml files into others?

3. If one has a node with duplicate entries, like from the earlier example....

<node>
    <childUniqueA/>
    <childUniqueB/>
    <childC/>
    <childC/> <!-- from doc 2 -->
</node>

How can I return the last entry of "childC" (from doc 2) rather than the first entry. Reason being - for some settings, I would like the duplicates to override the previous entries.

Thank you for any assistance!
