Method Detail

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(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.

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(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.

publicId

public static 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 String publicId(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

systemId

public static 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 String systemId(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
