    public class XPathException

extends javax.xml.transform.TransformerException

This class implements an exception object that all XPath classes will throw in case of an error. This class extends TransformerException, and may hold other exceptions. In the case of nested exceptions, printStackTrace will dump all the traces of the nested exceptions, not just the trace of this object.

Method Detail

### getStylesheetNode

    public java.lang.Object getStylesheetNode()

  Get the stylesheet node from where this error originated.

  Returns:
    The stylesheet node from where this error originated, or null.

### setStylesheetNode

    public void setStylesheetNode(java.lang.Object styleNode)
