XML sorting

[anilbisen]

I am working on an application which requires merging of XML documents
and then reorder/sort them based on elements in the XML. This needs to
be done in C++ and requires very high performance.
I read about sorting using XSLT but it is memory intensive and
performance is low and may not be useful to me.

Is there any other way I can achieve this?
Please guide me on this.

If performance is hypercritical, get an XML parser, use it to build your
own data structures which are optimized for your task, manipulate them
appropriately, and write the result out as XML (probably using the
serializer that came with the parser).
