Method Detail

getXSLStringValue

public static String getXSLStringValue(Node node)

Returns the XSL-defined string value for the specified node.

Parameters:

node - the node whose string value is to be returned

Returns:

the node's string value

getXSLStringValue

public static String getXSLStringValue(List nodeList)

Returns the XSL-defined string value for the specified node list.

Parameters:

nodeList - the node list whose string value is to be returned

Returns:

the node list's string value

parseLang

public static Locale parseLang(String lang)
                        throws IllegalArgumentException

Parses the value of the specified xml:lang value and returns a corresponding java.util.Locale object.

Currently this method supports the two-letter language codes defined by ISO-639 and the two-letter country codes defined by ISO-3166, since that is what the javadocs for java.util.Locale say it supports. This method does not yet support the IANA-defined and user-defined codes allowed in XML 1.0.

Parameters:

lang - the xml:lang value to be parsed; null causes the current default locale to be returned

Returns:

the corresponding locale

Throws:

IllegalArgumentException - if the passed language string is invalid

unicodeEscape

public static String unicodeEscape(char ch)

Returns the specified character as a Java-style Unicode escape of the form "\\uXXXX".

Parameters:

ch - the character to escape

Returns:

the Java-style Unicode escape

stripWhitespaceNode

public static boolean stripWhitespaceNode(Node node)

Evaluate a stylesheet node to see if it should be stripped according to the XSL whitespace stripping rules

Parameters:

node - the DOM node to evaluate

Returns:

true if node should be stripped

getWildcardNamePriority

public static double getWildcardNamePriority(WildcardName name)

Convenience function to return the default priority for a WildcardName. This exists so it can be used by com.novell.xsl.process.ElementMatch and com.novell.xsl.pattern.NodeTestPattern

Parameters:

name - The WildcardName to examine.

Returns:

The default priority of the passed WildcardName

indent

public static void indent(PrintWriter writer,
                          int tabs)

Output specified number of tabs.

Parameters:

writer - PrintWriter to output to.

tabs - Number of tabs to output.
