- - ### Constructor Detail

    - #### XPathException

          public XPathException(String message)

      Creates a new `XPathException` with a detail message.

      Parameters:
        `message` - a string indicating the specific problem

    - #### XPathException

          public XPathException(String message,
                                Throwable cause)

      Creates a new `IllegalNameException` with a detail message and an underlying root cause.

      Parameters:
        `message` - a string indicating the specific problem
        `cause` - the original cause of this exception

  - ### Method Detail

    - #### getCause

          public Throwable getCause()

      Return the original cause that led to this exception, or null if there was no original exception.

      Overrides:
        `getCause` in class `Throwable`
      Returns:
        the root cause of this exception

    - #### initCause

          public Throwable initCause(Throwable cause)

      Sets the root cause of this exception. This may only be called once. Subsequent calls throw an `IllegalStateException`.

      This method is unnecessary in Java 1.4 where it could easily be inherited from the superclass. However, including it here allows this method to be used in Java 1.3 and earlier.

      Overrides:
        `initCause` in class `Throwable`
      Parameters:
        `cause` - the root cause of this exception
      Returns:
        this `XMLException`
      Throws:
        `IllegalArgumentException` - if the cause is this exception (An exception cannot be its own cause.)
        `IllegalStateException` - if this method is called twice

    - #### getXPath

          public String getXPath()

      Returns the specific XPath expression being evaluated when this excepiton was thrown.

      Returns:
        the XPath expression that caused the exception
