virtualost::XMLStream::~XMLStream()[protected],[virtual]

       This class impliments a basic XML stream parser that can be used to examine an XML resource thru virtual
       I/O methods.

       This class must be derived into one that can impliment the physical I/O required to parse actual data. A
       mixer class using XMLStream and URLStream would seem a likely combination for this purpose.

       XML Stream Parser (SAX)

       Examplesxmlfetch.cpp.

virtualvoidost::XMLStream::characters(constunsignedchar*text,size_tlen)[purevirtual]
       Virtual to receive character text extracted from the document in the current element.

       Parameterstext received.
           len length of text received.

   virtualvoidost::XMLStream::close(void)[virtual]
       May perform a close operation of an i/o source when the parser has completed operation.

   virtualvoidost::XMLStream::comment(constunsignedchar*text,size_tlen)[virtual]
       Virtual to receive embedded comments in an XML document being parsed.

       Parameterstext text comment extracted.
           len length of comment.

   virtualvoidost::XMLStream::endDocument(void)[virtual]
       Identify end of document event.

   virtualvoidost::XMLStream::endElement(constunsignedchar*name)[purevirtual]
       Identify end of an element in the document.

       Parametersname of element found.

   virtualSlog::Levelost::XMLStream::getLogging(void)[virtual]
       Get error logging level.

       Returns
           error logging level.

   virtualboolost::XMLStream::open(constchar*resource)[virtual]
       May perform an open operation on behalf of a parsed resource. In some cases, the parser may be merged
       with a class that already has performed some kind of open, and this method can then be ignored.

       Returns
           true if open is successful.

       Parametersresource passed to Parse methods.

   boolost::XMLStream::parse(constchar*resource=NULL)
       Parse a resource as a stream thru the virtual read method.

       Returns
           true if well formed document has been fully parsed.

       Parametersresource optional name of resource.

   virtualintost::XMLStream::read(unsignedchar*buffer,size_tlen)[purevirtual]
       Read method to aquire data for the parser.

       Returns
           number of bytes actually read.

       Parametersbuffer to read data into.
           len number of bytes to read.

   virtualvoidost::XMLStream::startDocument(void)[virtual]
       Identify start of document event.

   virtualvoidost::XMLStream::startElement(constunsignedchar*name,constunsignedchar**attr)[purevirtual]
       Identify start of an element in the document.

       Parametersname of element found.
           attr list of attributes extracted.
