Class xml_document

Synopsis

#include <src/pugixml.hpp>

class PUGIXML_CLASS xml_document: public xml_node

Description

Document class (DOM tree root)

Mentioned in

Inheritance

Ancestors: xml_node

Methods

xml_document overloadDefault constructor, makes empty document.
xml_document overloadMove semantics support.
~xml_documentDestructor, invalidates all node/attribute handles to this document.
document_elementGet document element.
load overloadLoad document from stream.
load overload(deprecated: use load_string instead) Load document from zero-terminated string. No encoding conversions are applied.
load_bufferLoad document from buffer. Copies/converts the buffer, so it may be deleted or changed after the function returns.
load_buffer_inplaceLoad document from buffer, using the buffer for in-place parsing (the buffer is modified and used for storage of document data)
load_buffer_inplace_ownLoad document from buffer, using the buffer for in-place parsing (the buffer is modified and used for storage of document data)
load_file overloadLoad document from file.
load_stringLoad document from zero-terminated string. No encoding conversions are applied.
operator=
reset overloadRemoves all nodes, leaving the empty document.
reset overloadRemoves all nodes, then copies the entire contents of the specified document.
save overloadSave XML document to writer (semantics is slightly different from xml_node::print, see documentation for details).
save overloadSave XML document to stream (semantics is slightly different from xml_node::print, see documentation for details).
save_file overloadSave XML to file.
