### NodeInfo

    public NodeInfo()

Method Detail

### systemId

    public static java.lang.String systemId(ExpressionContext context)

  `systemId` returns the system id of the current context node.

  Parameters:
    `context` - an `ExpressionContext` value
  Returns:
    a `String` value

### systemId

    public static java.lang.String systemId(org.w3c.dom.NodeList nodeList)

  `systemId` returns the system id of the node passed as argument. If a node set is passed as argument, the system id of the first node in the set is returned.

  Parameters:
    `nodeList` - a `NodeList` value
  Returns:
    a `String` value

### publicId

    public static java.lang.String publicId(ExpressionContext context)

  `publicId` returns the public identifier of the current context node. Xalan does not currently record this value, and will return null.

  Parameters:
    `context` - an `ExpressionContext` value
  Returns:
    a `String` value

### publicId

    public static java.lang.String publicId(org.w3c.dom.NodeList nodeList)

  `publicId` returns the public identifier of the node passed as argument. If a node set is passed as argument, the public identifier of the first node in the set is returned. Xalan does not currently record this value, and will return null.

  Parameters:
    `nodeList` - a `NodeList` value
  Returns:
    a `String` value

### lineNumber

    public static int lineNumber(ExpressionContext context)

  `lineNumber` returns the line number of the current context node. NOTE: Xalan does not normally record location information for each node. To obtain it, you must set the custom TrAX attribute "http://xml.apache.org/xalan/features/source_location" true in the TransformerFactory before generating the Transformer and executing the stylesheet. Storage cost per node will be noticably increased in this mode.

  Parameters:
    `context` - an `ExpressionContext` value
  Returns:
    an `int` value. This may be -1 to indicate that the line number is not known.

### lineNumber

    public static int lineNumber(org.w3c.dom.NodeList nodeList)

  `lineNumber` returns the line number of the node passed as argument. If a node set is passed as argument, the line number of the first node in the set is returned. NOTE: Xalan does not normally record location information for each node. To obtain it, you must set the custom TrAX attribute "http://xml.apache.org/xalan/features/source_location" true in the TransformerFactory before generating the Transformer and executing the stylesheet. Storage cost per node will be noticably increased in this mode.

  Parameters:
    `nodeList` - a `NodeList` value
  Returns:
    an `int` value. This may be -1 to indicate that the line number is not known.

### columnNumber

    public static int columnNumber(ExpressionContext context)

  `columnNumber` returns the column number of the current context node. NOTE: Xalan does not normally record location information for each node. To obtain it, you must set the custom TrAX attribute "http://xml.apache.org/xalan/features/source_location" true in the TransformerFactory before generating the Transformer and executing the stylesheet. Storage cost per node will be noticably increased in this mode.

  Parameters:
    `context` - an `ExpressionContext` value
  Returns:
    an `int` value. This may be -1 to indicate that the column number is not known.

### columnNumber

    public static int columnNumber(org.w3c.dom.NodeList nodeList)

  `columnNumber` returns the column number of the node passed as argument. If a node set is passed as argument, the line number of the first node in the set is returned. NOTE: Xalan does not normally record location information for each node. To obtain it, you must set the custom TrAX attribute "http://xml.apache.org/xalan/features/source_location" true in the TransformerFactory before generating the Transformer and executing the stylesheet. Storage cost per node will be noticably increased in this mode.

  Parameters:
    `nodeList` - a `NodeList` value
  Returns:
    an `int` value. This may be -1 to indicate that the column number is not known.
