Method Detail

parsingError

boolean parsingError(int errorId,
                     String tag,
                     String attribute,
                     String value,
                     String description)

Called when encountering an error while parsing the XML document. When implementing this, the developer should return true if the error should be ignored and the document needs to be further parsed, or false to stop parsing and issue an error to the user Note that this method is always called NOT on the EDT thread.

Parameters:

errorId - The error ID, one of the ERROR_* constants

tag - The tag in which the error occured (Can be null for non-tag related errors)

attribute - The attribute in which the error occured (Can be null for non-attribute related errors)

value - The value in which the error occured (Can be null for non-value related errors)

description - A verbal description of the error

Returns:

true to continue parsing, false to stop
