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(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(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(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(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.
