Class DOMUtil

    java.lang.Object
      org.apache.xerces.util.DOMUtil

    public class DOMUtil

extends java.lang.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.
