class XML_Parser

An actual parser.

Public Methods

	~XML_Parser () Destructor, may close input if required
void	track_context (bool flag) Request that parser keep track of the currently open elements.
void	track_contents (bool flag) Keep track of the content of open elements.
EST_String	context (int n) Get the name of the nth enclosing element.
void	go () Run the parser.

Protected Fields

XML_Parser_Class*	pclass The class to which this parser belogs.
XBit	current_bit The piece of markup being processed
InputSource	source Where we are reading from
Entity	initial_entity The entity we started from.
void*	data Arbitrary data which can beused by callbacks
Parser	p The RXP parser object
EST_TDeque<EST_String>	p_context If context is being tracked, this is a stack of element names

Protected Methods

	XML_Parser (XML_Parser_Class &parent, InputSource source, Entity initial_entity, void* data) Creator used by XML_Parser_Class::make_parser()
InputSource	open (Entity ent) Open.
const char*	get_error () Get the error message for the last error

Documentation

An actual parser. Each such instance parses just one stream which is given when the parser is created.

The behaviour of the parser is given by the class to which it belongs.

XML_Parser_Class* pclass

The class to which this parser belogs. Defines the behaviour of the parser.

XBit current_bit

The piece of markup being processed

InputSource source

Where we are reading from

Entity initial_entity

The entity we started from. May beed to be freed at the end of the parse.

void* data

Arbitrary data which can beused by callbacks

Parser p

The RXP parser object

EST_TDeque<EST_String> p_context

If context is being tracked, this is a stack of element names

XML_Parser(XML_Parser_Class &parent, InputSource source, Entity initial_entity, void* data)

Creator used by XML_Parser_Class::make_parser()

InputSource open(Entity ent)

Open. Asks the parser class to do the work.

const char* get_error()

Get the error message for the last error

~XML_Parser()

Destructor, may close input if required

void track_context(bool flag)

Request that parser keep track of the currently open elements.

These are recorded on a atsck. Use context() to access the information.

void track_contents(bool flag)

Keep track of the content of open elements.

Not yet implemented.

EST_String context(int n)

Get the name of the nth enclosing element.

context(0) is the element we are directly inside.

void go()

Run the parser.

This class has no child classes.
