 XercesParser.java

dleslie     02/01/16 07:59:05

  Modified:    src/org/apache/stylebook/parsers XercesParser.java
  Log:
  Replaced DOMParser with an identity transormation to produce
  input DOM objects.
  This change required to sidestep a problem that appears with
  Xerces-J2beta4 and the JAVAX 1.1 DocumentBuilder. Works
  with Xerces-J1.44, Xerces-J2beta4, and presumably Crimson.
