cvs commit: xml-xalan/java/src/org/apache/xalan/xsltc/trax TransformerImpl.java
zongaro 2002/08/13 14:19:08
Modified: java/src/org/apache/xalan/xsltc/trax Tag: XSLTC_DTM
TransformerImpl.java
Log:
Picked up latest changes from MAIN branch, as well as a fix for id/key from
revision 1.42 that I merged incorrectly. Also, in getDOM method, temporarily
switched use of DOMImpl in DOMSource case to use DOM2SAX and SAXImpl, just to
get things going for the trax.dom flavor.
