Using Boost to read and write XML files

Is there any good way (and a simple way too) using Boost to read and write XML files?

I can't seem to find any simple sample to read XML files using Boost. Can you point me a simple sample that uses Boost for reading and writing XML files?

If not Boost, is there any good and simple library to read and write XML files that you can recommend? (it must be a C++ library)

c++ xml boost

You should Try pugixml Light-weight, simple and fast XML parser for C++

The nicest thing about pugixml is the XPath support, which TinyXML and RapidXML lack.

Quoting RapidXML's author "I would like to thank Arseny Kapoulkine for his work on pugixml, which was an inspiration for this project" and "5% - 30% faster than pugixml, the fastest XML parser I know of" He had tested against version 0.3 of pugixml, which has reached recently version 0.42.

Here is an excerpt from pugixml documentation:

The main features are:

  • low memory consumption and fragmentation (the win over pugxml is ~1.3 times, TinyXML - ~2.5 times, Xerces (DOM) - ~4.3 times 1). Exact numbers can be seen in Comparison with existing parsers section.
  • extremely high parsing speed (the win over pugxml is ~6 times, TinyXML - ~10 times, Xerces-DOM - ~17.6 times 1
  • extremely high parsing speed (well, I'm repeating myself, but it's so fast, that it outperforms Expat by 2.8 times on test XML) 2
  • more or less standard-conformant (it will parse any standard-compliant file correctly, with the exception of DTD related issues)
  • pretty much error-ignorant (it will not choke on something like You & Me, like expat will; it will parse files with data in wrong encoding; and so on)
  • clean interface (a heavily refactored pugxml's one)
  • more or less Unicode-aware (actually, it assumes UTF-8 encoding of the input data, though it will readily work with ANSI - no UTF-16 for now (see Future work), with helper conversion functions (UTF-8 <-> UTF-16/32 (whatever is the default for std::wstring & wchar_t))
  • fully standard compliant C++ code (approved by Comeau strict mode); the library is multiplatform (see reference for platforms list)
  • high flexibility. You can control many aspects of file parsing and DOM tree building via parsing op

A warning. I love RapidXML, but it has a very nasty bug when parsing UTF16. Some valid values cause it to crash.

I would love to recommend pugixml - but it lacks namespace support, which I know is going to cause me problems.

What about boost.spirit?

Here, they show a "Mini XML" parser
