      • ValidityException

        public ValidityException​(String message)

        Creates a new ValidityException with a detail message.

        Parameters:
        message - a string indicating the specific problem
    • Method Detail

      • getDocument

        public Document getDocument()

        Returns a Document object for the document that caused this exception. This is useful if you want notification of validity errors, but nonetheless wish to further process the invalid document.

        Returns:
        the invalid document
      • getErrorCount

        public int getErrorCount()

        Returns the number of validity errors the parser detected in the document. This is likely to not be consistent from one parser to another.

        Returns:
        the number of validity errors the parser detected
      • getValidityError

        public String getValidityError​(int n)

        Returns a message indicating a specific validity problem in the input document as detected by the parser. Normally, these will be in the order they appear in the document. For instance, an error in the root element is likely to appear before an error in a child element. However, this depends on the underlying parser and is not guaranteed.

        Parameters:
        n - the index of the validity error to report
        Returns:
        a string describing the nth validity error
        Throws:
        IndexOutOfBoundsException - if n is greater than or equal to the number of errors detected
      • getLineNumber

        public int getLineNumber​(int n)

        Returns the line number of the nth validity error. It returns -1 if this is not known. This number may be helpful for debugging, but should not be relied on. Different parsers may set it differently. For instance a problem with an element might be reported using the line number of the start-tag or the line number of the end-tag.

        Parameters:
        n - the index of the validity error to report
        Returns:
        the approximate line number where the nth validity error was detected
        Throws:
        IndexOutOfBoundsException - if n is greater than or equal to the number of errors detected
      • getColumnNumber

        public int getColumnNumber​(int n)

        Returns the column number of the nth validity error. It returns -1 if this is not known. This number may be helpful for debugging, but should not be relied on. Different parsers may set it differently. For instance a problem with an element might be reported using the column of the < or the > of the start-tag

        Parameters:
        n - the index of the validity error to report
        Returns:
        the approximate column where the nth validity error was detected
        Throws:
        IndexOutOfBoundsException - if n is greater than or equal to the number of errors detected
