Rapidxml

官网 RapidXML

You may also like to check Boost.PropertyTree library, which presents a higher level interface, and uses RapidXml as its default XML parser.

NOTE: boost\property_tree\detail就用了`rapidxml.hpp。

RAPIDXML Manual

1.4 Memory Allocation

RapidXml uses a special memory pool object to allocate nodes and attributes, because direct allocation using new operator would be far too slow. Underlying memory allocations performed by the pool can be customized by use of memory_pool::set_allocator() function. See class memory_pool for more information.

NOTE:

1、值得借鉴，函数原型:

void set_allocator(alloc_func *af, free_func *ff);
