Previously we omitted extra whitespace for single PCDATA/CDATA children, but in mixed content there was extra indentation before/after text nodes. One of the problems with that is that the text that you saved is not exactly the same as the parsing result using default flags (parse_trim_pcdata helps). Another problem is that parse-format cycles do not have a fixed point for mixed content - the result expands indefinitely. Some XML libraries, like Python minidom, have the same issue, but this is definitely a problem. Pretty-printing mixed content is hard. It seems that the only other sensible choice is to switch mixed content nodes to raw formatting. In a way the code in this change is a weaker version of that - it removes indentation around text nodes but still keeps it around element siblings/children. Thus we can switch to mixed-raw formatting at some point later, which will be a superset of the current behavior. To do this we have to either switch at the first text node (.NET XmlDocument does that), or scan the children of each element for a possible text node and switch before we output the first child. The former behavior seems non-intuitive (and a bit broken); unfortunately, the latter behavior can cost up to 20% of the output time for trees *without* mixed content. Fixes #13. |

pugixml 
pugixml is a C++ XML processing library, which consists of a DOM-like interface with rich traversal/modification capabilities, an extremely fast XML parser which constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven tree queries. Full Unicode support is also available, with Unicode interface variants and conversions between different Unicode encodings (which happen automatically during parsing/saving).
pugixml is used by a lot of projects, both open-source and proprietary, for performance and easy-to-use interface.
Documentation
Documentation for the current release of pugixml is available on-line as two separate documents:
- Quick-start guide, that aims to provide enough information to start using the library;
- Complete reference manual, that describes all features of the library in detail.
You’re advised to start with the quick-start guide; however, many important library features are either not described in it at all or only mentioned briefly; if you require more information you should read the complete manual.
