All Implemented Interfaces:

ErrorListener

Enclosing class:

AbstractXSLProcessingStage

public class AbstractXSLProcessingStage.StatusInfoAppendingErrorListener
extends Object
implements ErrorListener

Transformer ErrorListener that sets an ErrorStatus or WarningStatus on its Item depending on the TransformerException message. If the message begins with "[ERROR]" the remainder of the error message is used as the message for the added ErrorStatus. If the message begins with "[WARN]" the remainder of the error message is used as the message for the added WarningStatus. If the message begins with "[INFO]" the remainder of the error message is used as the message for the added InfoStatus. If the message does not begin with either prefix the exception is re-thrown to be handed by the Transformer. This listener works well in conjunction with <xsl:message>
