    How to pass XML requests to a PHP script

    My site is based on XML templates and uses a PHP script to turn them
    into XHTML. The script use the expat parser functions and works just
    fine. The XSLT extensions are not enabled on the server.

    At the moment I am passing requests for the XML files to the script by
    setting up .xml as a PHP file using AddType and then using a
    mod_rewrite rule to ensure that the request gets handled by the script
    (don't laugh!). This is all set up in .htaccess which is all I have
    access to.

    It's worked fine like this for the past year or so but is, I guess, not
    the best way to do it. I'm guessing that there's probably some way to
    do this using AddHandler and Action directives (or something) which
    would be more 'correct'.

    What's the best way to achieve this. Server is virtual running on
    Apache 1.3.27 (Linux).

      Something like http://www.example.com/transform.php/filename.xml, perhaps?
      The PHP script will get the name of the XML file in $_SERVER['PATH_INFO'].

          I think the AddType for xml is a red herring. If your mod_rewrite rules
          terminate with an internal location that ends .php (or whatever extension
          you've already got set up to handle PHP) then the URL the outside world ever
          sees can end with whatever you like.

          e.g.
          RewriteEngine On
          RewriteRule ^/images/([^/]+)\.jpg /serve_image.php ?filename=$1 [L]

          will work just fine.

          I often do:

          RewriteEngine On
          RewriteRule ^/internal/ - [F]

          then map the odd URLs onto scripts in an 'internal' directory, just to be
          damn sure no-one will call them from outside. It pinches a bit of the
          namespace for external URLs, but it's nice and explicit. It also means you
          can be pretty sure that something that's a numeric parameter really is, just
          in the RewriteRules.

              Yes, you're right it is. It's a hang over from an earlier attempt to do
              this. What I'm actually trying to do is to avoid using mod_rewrite for
              this at all though and having looked through the Apache docs properly
              this time I've found the answer was staring me in the face all along. I
              just use something like:

              Action add-xmlstuff /xml_handler.php
              AddHandler add-xmlstuff .xml

              don't I? Then all requests for .xml files get passed to xml_handler.php
              and everything's hunk dory. I have to play around with PATH_TRANSLATED
              a bit to extract some info but that's dead easy (at least on servers
              where document_root is exported to $_SERVER).

              Or am I still barking up a gum tree?
