The module is filter that transforms XML using one or more XSLTs.
The module requires libxml2/libxslt libraries.

There are 3 directives (all are available on http/server/location
levels):

xml_entities /path/to/entities.dtd;

The modules ignores external subset in XML, therefore it needs some DTD
to resolve symbol entities.

xslt_stylesheet /path/to/some.xslt param1=value1 param2=value2;

Stylesheet and parameters. There can be several stylesheets, running
in order description:

xslt_stylesheet /path/to/some1.xslt param1=value1 param2=value2;
xslt_stylesheet /path/to/some2.xslt param1=value1;

The parameters can be one string, separated by “:”:

param1=value1:param2=value2;

The variables can be use in paramters:

param1=$value1:param2=value2;

or even

xslt_stylesheet /path/to/some1.xslt $arg_xslt_params;

The “:” in parameter value must be escaped as %3A.

xslt_types text/xml;

MIME-types to processes.

*) Feature: the “$arg_…” variables.

Also ^

This is values from query string, e.g:

/uri??one=1&two=2

appropriately $arg_one is “1” and $arg_two is “2”.

I assume that was put in to help with the XSLT processing?

Would it be possible to set a response header from some script (like
PHP), to trigger an XSL translation on a response? For instance:

X-XSLTranslate: /path/to/file.xsl
X-XSLParam: name1 value1
X-XSLParam: name2 value2
X-XSLParam: name3 value3

I feel this would be a useful extension to this module.

You may set parameters, but not XSL:

xslt_stylesheet    /site/xslt/one.xslt
                   $upstream_http_x_xslt_params;

X-XSLT-Params: name1=value1:name2=value2:name3=value3

X-XSLT-Params: name1=value1:name2=value2:name3=value3

No plans to extend this then? I’ve just thought of something else which
would be useful, although it might be more difficult; having the module
check the XML file for a processing instruction and applying that.
Specifying the stylesheet in the nginx config is useful, but also quite
limiting.

Yes.
