Modified: java/src/org/apache/xalan/xsltc/dom Tag: XSLTC_DTM
SAXImpl.java
Log:
XSLTC_DTM performance work
Improvement for xsl:copy-of. Instead of using the expensive
getFirstAttribute()
and getFirstNamespace() interfaces, increase the element id by 1 to iterate
through all attribute and namespace nodes.
