Package overview: net.sf.saxon.regex
This package contains the code to map XML Schema and XPath regular expressions
to a regular expression engine of the underlying Java platform.
Most of the classes implement a regular expression engine derived from Apache's Jakarta
project. The code of Jakarta has been modified so that the regular expressions implement
the syntax of XSD/XPath regular expressions. There have also been extensive changes
for performance reasons
In addition, there are classes to provide direct access to the native JDK
regular expression engine. The flags value ";j" may be used to select this
engine. The resulting syntax/semantics will not be an exact match to the XPath
definition.
Users should not normally need to use these classes directly.
Earlier versions of Saxon included a translator from XPath regular expressions
to Java regular expressions, based on that produced by James Clark. This
mechanism is no longer used.
