Macro used to express that the API use the new buffers for xmlParserInputBuffer and xmlOutputBuffer. The change was introduced in 2.9.0.

This is the namespace for the special xml: prefix predefined in the XML Namespace specification.
#define xmlChildrenNode;
Macro for compatibility naming layer with libxml1. Maps to "children."
#define xmlRootNode;
Macro for compatibility naming layer with libxml1. Maps to "children".
