Subject: About stylesheet href From: "Didier PH Martin" <martind@xxxxxxxxxxxxx> Date: Tue, 26 Jan 1999 20:58:01 -0500 |
Hi J-P I made an error in the last message. I made several trial and found that Jade do not support sysids defined in a catalog. It has to be a storage location. In fact, I discovered that XML stylesheets share the same weakeness. xml:stylesheet href is a URL and therefore is location dependant. The catalog mechanis was brought to provide a location independence to identifiers. The catalog is providing a certain indirection to real storages. Thus, your document contain identifiers that are location independent and can then be transported. If, in the catalog you are using relative path like "../common/MyImage.jpeg" you can even move the whole collection without having to redo your catalog. So it seeems that the stylesheet PI do not have this location independence or maybe I am making a error. Am I? (to other guys on this list). In the SGMLKit I implemented an other way that indeed work. to provide location independance, with the sgmlKit you don't include a PI. Instead, in the SCRIPT directory (located under the root directory where the SGMLKit is installed), you update the SCRIPTS file. That file is a bit like catalog but includes COMMAND tags. You associate a DOCTYPE to a Jade command line with two markups. This way, all documents having this doctype are associated to this command line. It is more economical than to redo each time the same thing. A SCRIPTS file entry looks like: COMMAND <DOCTYPE="-//Free Text Project//DTD Play//EN"> <script = jade -t rtf -o $DOCVIEW -d "$SCRIPT_DIR/play/play.dsl" > So each time you select a document with that DOCTYPE the Jade command line is used to render it. This is experimental stuff but it is working in the last version of the SGMLKit. The above line means that the document is rendered in the docview and that the script is located in the play directory itself located under the Scripts directory. You can also use an absolute path to indicate the script location. The -o parameter is optional. Anyway, I'll look at what can be done with the stylesheet PI. What about this: <?xml:stylesheet href="<catalog>sysid" type="text/dsssl" format="tex"?> So, it the preprocessor encounter the <catalog> tag in href, it look for: SYSTEM sysid "dir1/dir2/script.dsl" then replace the href value by "dir1/dir2/script.dsl" So the dsssl engine would receive the following PI: <?xml:stylesheet href="dir1/dir2/script.dsl" type="text/dsssl" format="tex"?> and would work OK. What do you think of this solution? Regards Didier PH Martin mailto:martind@xxxxxxxxxxxxx http://www.netfolder.com DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
