Class DOMUtil
public
class
DOMUtil
extends Object
Some useful utility methods.
This class was modified in Xerces2 with a view to abstracting as
much as possible away from the representation of the underlying
parsed structure (i.e., the DOM). This was done so that, if Xerces
ever adopts an in-memory representation more efficient than the DOM
(such as a DTM), we should easily be able to convert our schema
parsing to utilize it.

protected DOMUtil()
This class cannot be instantiated.
public static void copyInto(Node src, Node dest)
Copies the source tree into the specified place in a destination
tree. The source node and its children are appended as children
of the destination node.
Note: This is an iterative implementation.
public static Attr getAttr(Element elem, String name)
public static Attr getAttrNS(Element elem, String nsUri, String localName)
public static Attr[] getAttrs(Element elem)
public static String getAttrValue(Element elem, String name)
public static String getAttrValueNS(Element elem, String nsUri, String localName)
public static String getChildText(Node node)
Returns the concatenated child text of the specified node.
This method only looks at the immediate children of type
Node.TEXT_NODE
or the children of any child
node that is of type
Node.CDATA_SECTION_NODE
for the concatenation.
Parameters: node The node to look at.

Finds and returns the first child node with the given name.
public static Element getFirstChildElement(Node parent, String elemName, String attrName, String attrValue)
Finds and returns the first child node with the given name and
attribute name, value pair.
