public void parse(InputSource input)
           throws IOException,

```
    Parses an XML document.
    The application can use this method to instruct the data source to begin parsing an XML document from any valid input source (a character stream, a byte stream, or a URI).
    Applications may not invoke this method while parsing is in progress. During parsing, the data source notifies its listeners of any changes.
    This method is synchronous: it does not return until parsing has ended. If a client application wants to terminate parsing early, it should throw an exception.
    By default, the XML document is validated.
    
    Parameters:
    
    input - The input source for the top level of the XML document.
    
    Throws:
    
    SAXException - that is any SAX exception, possibly wrapping another exception.
    
    IOException - which is an IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

  - setFileName
```
public void setFileName(String fileName)
```
    Parses an XML file from the file name. The data source is cleared before parsing the specified document.
    This method performs a synchronous (that is a regular) call to parse().
    All exceptions are caught. In order to handle them you should implement your own mechanism, using one of the parse() methods.
    
    Parameters:
    
    fileName - File name of the XML document to read. It is resolved to an absolute URL using the IlpURLAccessService. If you pass null, the data source will be cleared. If you pass the same file name as the current one of the data source, the data source will be cleared and reloaded.
    
    See Also:
    
    parse(String)
  - setFileName
```
public void setFileName(String fileName,
                        boolean parse)
```
    Sets the file name that is used by this datasource.
    If parse is false only the file name is changed and no parsing takes place.
    If parse is true it changes the file name and parses an XML file from the file name provided. The data source is cleared before parsing the specified document.
    In the latter case, this method performs a synchronous (that is a regular) call to parse().
    Also all exceptions are caught. In order to handle them you should implement your own mechanism, using one of the parse() methods.
    
    Parameters:
    
    fileName - File name of the XML document to read. It is resolved to an absolute URL using the IlpURLAccessService. If you pass null, the data source will be cleared. If you pass the same file name as the current one of the data source, the data source will be cleared and reloaded.
    
    parse - If true, the file will be parsed as a result of this method. Otherwise, no parsing will take place and the file name is changed accordingly.
