Class XPathUtil

java.lang.Object
  com.novell.xml.xpath.XPathUtil

public final class XPathUtil

extends Object

A utility class that gathers XPath functions together that don't fit under a real class.

Method Summary

static String	describeNode(Node node) Provide a textual representation of a node, suitable for debugging.
static Class	doGetClass(String className) Get a class object by name without worrying about a ClassNotFound exception.
static void	dump(Object obj, PrintWriter writer, int indent) Print in a readable form for debugging.
static Node	getNextSibling(Node node) Helper function to get next sibling of a Node, treating adjacent text nodes as a single text node.
static short	getNodeType(Node node) Returns the DOM Node Type, except Node.CDATA_SECTION_NODE is returned as Node.TEXT_NODE.
static String	getNodeValue(Node node) Return the XPath-defined node value for the passed node.
static Node	getPreviousSibling(Node node) Helper function to get previous sibling of a Node, treating adjacent text nodes as a single text node.

Method Detail

getNodeType

public static short getNodeType(Node node)

Returns the DOM Node Type, except Node.CDATA_SECTION_NODE is returned as Node.TEXT_NODE.

Parameters:

node - Node whose type is to be returned.

Returns:

node type

getNodeValue

public static String getNodeValue(Node node)

Return the XPath-defined node value for the passed node.

Parameters:

node - The node whose value is desired.

Returns:

A string containing the node value.

getNextSibling

public static Node getNextSibling(Node node)

Helper function to get next sibling of a Node, treating adjacent text nodes as a single text node.

Parameters:

node - Node whose next sibling is to be returned

Returns:

null or the next sibling in the XPath data model.

getPreviousSibling

public static Node getPreviousSibling(Node node)

Helper function to get previous sibling of a Node, treating adjacent text nodes as a single text node.

Parameters:

node - Node whose previous sibling is to be returned

Returns:

null or the previous sibling in the XPath data model.

doGetClass

public static Class doGetClass(String className)

Get a class object by name without worrying about a ClassNotFound exception.

Parameters:

className - The name of the Class object to get.

Returns:

The Class object.

describeNode

public static String describeNode(Node node)

Provide a textual representation of a node, suitable for debugging. This "overrides" the DOMUtil version so we can handle XPath-specific node types (namespace nodes).

Parameters:

node - The node to be described.

Returns:

A string containing a textual representation of the node.

dump

public static void dump(Object obj,
                        PrintWriter writer,
                        int indent)

Print in a readable form for debugging.

Parameters:

obj - The object to output.

writer - The output device.

indent - Number of tabs to indent the result.
