NGINX recently added support for XSL transformations, and it is AWESOME! In fact, its one of the coolest pieces of software I've used in a long time.
Its very simple. The extra cool part of the module is how the templates can be chained together, and it almost seems like a stream editor in a way. Its also very fast!
The example from the NGINX modules website:
location / {
xml_entities /site/dtd/entities.dtd;
xslt_stylesheet /site/xslt/one.xslt param=value;
xslt_stylesheet /site/xslt/two.xslt;
}
This is so cool because you can dynamically combine and mesh all sorts of xml documents together. The xml documents can come from a variety of sources - local static XML files or remote dynamic files generated from a database.
This is really, really great!
UPDATE: What's even more amazing about this module is that it works with FastCGI output, like this:
location = /cgi-bin/barf.cgi {
xslt_types text/html;
add_header Cache-Control: no-store;
fastcgi_pass unix:/tmp/fcgi.sock;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param TARGET_FILENAME $arg_TARGET_FILENAME;
xslt_stylesheet /var/www/public/a/webop/templates/xsl/status_services.xsl mynid="$arg_nid";
}
This means I can use a scripting language like PHP, Perl, Python, Ruby, Tcl, Lua or really anything to generate XML, and then it will be transformed via the NGINX xslt module. Sooooo cooool!!!
Whoa! It also works with proxy_pass!!!!!
