XSLT Filter

The XSLT Filter is a powerful Apache2 loadable module that allows you to perform XSL transformations on-the-fly. With LibXML2 and LibXSLT as its parsing and transformation engines, you can expect top-notch performance every time you use it. The module works as an Apache output filter, which means that it is compatible with mod_perl, CGI, and PHP applications.

Installing the XSLT Filter is a breeze. Simply unpack the module with tar, run the ./configure script, and then run the make and make install commands. Finally, restart your Apache2 server, and you're all set.

To enable the xslt_filter module, edit your httpd.conf file and add the following section:

LoadModule xslt_filter modules/xslt_filter.so
AddType text/xsl .xsl
AddType text/xml .xml
AddOutputFilterByType xslt_filter text/xml
AddOutputFilterByType xslt_filter application/xml

For each virtual server, you can use additional configuration options to customize your setup. For example, you can enable debugging output with the XSLT_Filter debug option. You can also define a root directory for your XSL files by using the XSLT_Filter xsltroot /usr/local/www/xslt option. Additionally, you can allow or deny the usage of external resources such as XML and XSL files with the XSLT_Filter external option.

Overall, the XSLT Filter is an excellent tool for anyone looking to perform XSL transformations in a fast and efficient manner. With its compatibility with various applications and easy installation process, it's definitely worth considering for anyone looking to improve their web development workflow.
