Cookbook: Using XSLT 2.0 stylesheets in post write hooks

PHP's built-in XSLT processor only supports XSLT 1.0. If you want to use XSLT 2.0 to clean up your MODS, you can do so by using an external XSLT processor. Developers at Louisiana State University Library have contributed a post-write hook script that uses the Saxon XSLT processor to apply XSLT 2.0 stylesheets to MODS XML files. They have also provided a brief overview. The script itself is fairly simple, but it applies a wide range of cleanup stylesheets to the MODS files.
