Modified: java/src/org/apache/xml/dtm/ref Tag: XSLTC_DTM
DTMDefaultBase.java
Log:
Added a getTypedAttribute method to make the process of finding a particular
attribute quicker than using getFirstAttribute and getNextAttribute. The
getTypedAttribute method will convert at most once to a node identity and
once to a node handle, where getFirstAttribute and getNextAttribute would for
each attribute checked.
