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.
copyInto
public static void copyInto(Node src,
Node dest)
throws DOMException
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.
getAttr
public static Attr getAttr(Element elem,
String name)
getAttrNS
public static Attr getAttrNS(Element elem,
String nsUri,
String localName)
getAttrValue
public static String getAttrValue(Element elem,

String localName)
getAttrs
public static Attr[] getAttrs(Element elem)
getChildText
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.
node
