Detailed Description

This is the abstract class that the XSL processor uses when it has a problem of some kind, that requires a message, an error or a warning.

Users should ask the XSLTProcessor class to setProblemListener if they wish an object instance to be called when a problem event occurs.

styleNode style tree node where the problem occurred (may be 0)

msg string message explaining the problem.

uri the URI of the document where the problem occurred. May be 0.

lineNo line number where the problem occurred.

charOffset character offset where the problem.
