// These node, element, and document classes implement a subset of the methods
// provided by NSXML. While NSXML behavior is mimicked as much as possible,
// there are important differences.
//
// The biggest difference is that, since this is based on libxml2, there
// is no retain model for the underlying node data. Rather than copy every
// node obtained from a parse tree (which would have a substantial memory
// impact), we rely on weak references, and it is up to the code that
// created a document to retain it for as long as any
// references rely on nodes inside that document tree.
#import <Foundation/Foundation.h>
// libxml includes require that the target Header Search Paths contain
//
// /usr/include/libxml2
//
// and Other Linker Flags contain
//
// -lxml2
#import <libxml/tree.h>
#import <libxml/parser.h>
