FYI: Xalan-C Custom XPath Extension Functions
I have updated my committer's web site with source code to implement and
test
some useful XPath extension functions. I also have a XalanCAPI based
application
that installs and tests these functions.
Go to my Committer's Web Page: http://www.apache.org/~shathaway
And download the "OspXpath.zip" file.
The cvdate() function will take as input most strings that represent a date.
Heuristic analysis is done to determine the format of the input string.
The output string can be rendered in many different standard formats.
The cvdate() is not locale dependent.
I also have a library of XPath functions that implements a rudimentary
database. You specify table names and key-value pairs. The underlying
linked lists create a virtual database that is managed with XPath functions
in stylesheets. This library allows you to implement variables that can
be dynamically reassigned. Rows in the virtual tables can be sorted.
A table can be exported to a node-set to be used in a for-each element.
This code is for instruction and prototype. It is not ready for including
into the Xalan-C product.
Enjoy!
