public final class Nodes
extends Object

Utility algorithms that work on DOM nodes.

Method Summary

Modifier and Type	Method and Description
static Map<QName,String>	getAttributes(Node n) Obtains an element's attributes as Map.
static String	getMergedNestedText(Node n) Tries to merge all direct Text and CDATA children of the given Node and concatenates their value.
static QName	getQName(Node n) Extracts a Node's name, namespace URI (if any) and prefix as a QName.
static Node	normalizeWhitespace(Node original) Creates a new Node (of the same type as the original node) that is similar to the orginal but doesn't contain any empty text or CDATA nodes and where all textual content including attribute values or comments are trimmed and normalized.
static Node	stripWhitespace(Node original) Creates a new Node (of the same type as the original node) that is similar to the orginal but doesn't contain any empty text or CDATA nodes and where all textual content including attribute values or comments are trimmed.

Method Detail

getQName

public static QName getQName(Node n)

Extracts a Node's name, namespace URI (if any) and prefix as a QName.

getMergedNestedText

public static String getMergedNestedText(Node n)

Tries to merge all direct Text and CDATA children of the given Node and concatenates their value.

Returns:

an empty string if the Node has no Text or CDATA children.

getAttributes

public static Map<QName,String> getAttributes(Node n)

Obtains an element's attributes as Map.

stripWhitespace

public static Node stripWhitespace(Node original)

Creates a new Node (of the same type as the original node) that is similar to the orginal but doesn't contain any empty text or CDATA nodes and where all textual content including attribute values or comments are trimmed.

normalizeWhitespace

public static Node normalizeWhitespace(Node original)

Creates a new Node (of the same type as the original node) that is similar to the orginal but doesn't contain any empty text or CDATA nodes and where all textual content including attribute values or comments are trimmed and normalized.

"normalized" in this context means all whitespace characters are replaced by space characters and consecutive whitespace characaters are collapsed.
