C++ XML parsing library for large files with low RAM consumpion

Which XML library for C++ uses the lowest amount of RAM while parsing e. g. 300M file? Ideally the choice should be restricted to one of RapidXml, Pugixml, Libxml, Boost, TinyXML.

You haven't clarified your complete requirements. There are 2 commonly used xml parsing models: DOM and SAX. In DOM the entire file is parsed into memory as a tree where as SAX is more of a event driven library. If you are

  1. not planning to modify the XML & just consume it and
  2. concerned about RAM usage

then using SAX model will be optimum. I will be surprised if half decent implementation of SAX is memory intensive. Also look at this post: Light weight C++ SAX XML parser
