Detailed Description
Input handler for the XML format.The a2dIOHandlerXML uses a fast, lightweight, event-driven XML parser (expat).
- Remarks:
- It's only a input handler, the a2dIOHandlerXML is not able to write XML data. Use a2dIOHandlerXMLPull to read and write data. a2dIOHandlerXMLPull also has an comfortable API to read / write data, so there's no need to use the a2dIOHandlerXML class directly if you want to create your own XML fileformat.

Constructor & Destructor Documentation
| a2dIOHandlerXML::a2dIOHandlerXML | ( | ) |
Constructor.
- Remarks:
- Before you can use this object you've to call the InitializeLoad() or InitializeSave() method
The standard IO handlers of wxArt2d (i.e. wxDocviewIOHandlerXmlSer) call the Initialize method in the Load... methods, an extra call to Initialize is not necessary.
- See also:
- InitializeLoad

Member Function Documentation
| void a2dIOHandlerXML::InitializeLoad | ( | ) | [virtual] |
Inits the handler for reading.
This method creates the parser and the buffer and also connects the Base...Hnd methods of this class with the parser.
- Remarks:
- You've to call this method before you can start doing something useful with this object!

| int a2dIOHandlerXML::GetCurrentColumnNumber | ( | ) | [virtual] |
Returns the current column no.
Returns the current column no. Mainly used for error msgs / debugging, but maybe usefull for other purposes.
- See also:

- Returns:
- current column no.
