Detailed Description

Used to parse an entire XML file.

When particular XML components are encountered, this will be signalled by calling corresponding routines from the XMLParserCallback that is passed to the XMLParser constructor.

To parse an entire XML file, simply call static routine parse_stream(), which does not require you to create an XMLParser yourself.

If you desire more fine-grained control over the parsing process, you may create an XMLParser yourself and parse the file manually in small pieces. To do this, routine parse_chunk() should be called repeatedly with consecutive pieces of the XML file. Once the entire XML file has been sent through parse_chunk(), routine finish() should be called once to signal that processing is complete.

Python:
Not present.

Constructor & Destructor Documentation

regina::xml::XMLParser::XMLParser ( XMLParserCallback callback  ) 

Creates a new XML parser.

Parameters:
callback the object providing the routines to call when particular XML components are encountered during parsing.

regina::xml::XMLParser::~XMLParser (  )  [inline, virtual]

Destroys this XML parser.


Member Function Documentation

void regina::xml::XMLParser::finish (  )  [inline]

Signals that there are no more XML chunks to parse.

void regina::xml::XMLParser::parse_chunk ( const std::string &  s  )  [inline]

Parses the given chunk of XML.

Parameters:
s the chunk of XML to parse.

static void regina::xml::XMLParser::parse_stream ( XMLParserCallback callback,
std::istream &  file,
unsigned  chunkSize = 1024 
) [static]

Parses an entire XML file.

The given stream will be read from until end-of-file is reached.

Parameters:
callback the object providing the routines to call when particular XML components are encountered during parsing.
file the stream from which the raw XML will be read.
chunkSize the number of characters to read and process at a time (this is the size of each string that will be passed to parse_chunk()).
