Detailed Description
XML streaming parser.
This class implements 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 implement the physical I/O required to parse actual data. A mixer class using XMLParser and tcpstream would be one example of this. This can also be used to parse xml content in memory buffers easily. This parser is only concerned with well-formedness, and does not perform validation.

Member Function Documentation
Virtual to receive character text extracted from the document.
- Parameters:
-
text | received. |
size | of text received. |
Virtual to receive embedded comments in XML document being parsed.
- Parameters:
-
text | received. |
size | of text received. |
End of document check.
- Returns:
- true if end of document.
Definition at line 144 of file xml.h.
Notify end of an element in the document.
- Parameters:
-
Parse a stream buffer and return parser document completion flag.
This is used to scan a stream buffer for a complete XML document. The stream is scanned until the document is complete or EOF. Multiple XML document instances can be scanned from a continues XML streaming source.
- Parameters:
-
- Returns:
- true if parse complete, false if invalid or EOF.
Parse a file buffer and return parser document completion flag.
This is used to scan a file buffer for a complete XML document. The file is scanned until the document is complete or EOF. Multiple XML document instances can be scanned from a continues XML streaming source.
- Parameters:
-
- Returns:
- true if parse complete, false if invalid or EOF.
Parse a chunk of data and return parser completion flag.
This is used to externally drive data into the XML parser. The return status can be used to determine when a document has been fully parsed. This can be called multiple times to push stream data into the parser.
- Parameters:
-
address | of data to parse. |
size | of data to parse. |
Notify start of an element in the document.
- Parameters:
-
name | of element found. |
attr | list of attributes extracted. |
