xlst template for simulink xml parsing

i'm trying to export a simulink webview (without the use of the report generator toolbox).

My thought was to convert the .slx file to .xml in matlab, then in python parse the .xml to .html.

this is my matlab code:

load_system('scSam') %scSam is the .slx model, mind it's just a dummy with some random blocks thrown in

save_system('xmltest', 'model_xml.xml','ExportToXML', true);

once i have the xml file, i parse it in python:

import lxml.html

from lxml import etree

xslt_doc = etree.parse("test-xslt.xslt") %this is the xslt template i'm using

xslt_transformer = etree.XSLT(xslt_doc)

source_doc = etree.parse("xmltest.xml")

output_doc = xslt_transformer(source_doc)

output_doc.write("htmltest.html", pretty_print=True)

my issue is that i cannot find or write a decent xlst stylesheet able to actually reproduce the simulink file.

I'm glad to hear some suggestions from you. Maybe this approach is overcomplicating things, or mabe there is a public simulink xlst file i don't know about. Or mabe this jsut can't be done withtout the toolbox

Edit: i'm thinking of doing the latter conversion part in Java, is it a good idea? i'm not really familiar with it other than the basics but i know it has some good xml libraries

Hello Luca,

As per my understanding, you want to export a Simulink model to web view. You are able to convert a Simulink model to XML file, but are having trouble converting XML to HTML file.

You can use the MATLAB function "xlst" for the second part of your workflow. "xlst" function is used to transform an XML document using XLST engine. For example, to convert a file "info.xml", using the stylesheet "info.xsl", to the file "info.html" and launch the resulting HTML file in the MATLAB Web Browser, an example code for the same would look like:

xslt('info.xml', 'info.xsl', 'info.html', '-web')

For more information on "xlst" function, you can refer to the following documentation:

Transform XML document using XSLT engine - MATLAB xslt (mathworks.com)

that's neat, since now i don't have to go through python to do it. Thanks!

Still, do you think i can retrieve somewhere a stylesheet for simulink xml files?
