How can I make XSLT work in chrome?

The other answer below by Eric is wrong. The namespace declaration he mentioned had nothing to do with the problem.

The real reason it doesn't work is due to security concerns (cf. issue 4197, issue 111905).

Imagine this scenario:

1. You receive an email message from an attacker containing a web page as an attachment, which you download.

2. You open the now-local web page in your browser.

3. The local web page creates an <iframe> whose source is https://mail.google.com/mail/.

4. Because you are logged in to Gmail, the frame loads the messages in your inbox.

5. The local web page reads the contents of the frame by using JavaScript to access frames[0].document.documentElement.innerHTML. (An online web page would not be able to perform this step because it would come from a non-Gmail origin; the same-origin policy would cause the read to fail.)

6. The local web page places the contents of your inbox into a <textarea> and submits the data via a form POST to the attacker's web server. Now the attacker has your inbox, which may be useful for spamming or identify theft.

Chrome foils the above scenario by putting restrictions on local files opened using Chrome. To overcome these restrictions, we've got two solutions:

1. Try running Chrome with the --allow-file-access-from-files flag. I've not tested this myself, but if it works, your system will now also be vulnerable to scenarios of the kind mentioned above.

2. Upload it to a host, and problem solved.

At the time of writing, there was a bug in chrome which required an xmlns attribute in order to trigger rendering:

<xsl:stylesheet xmlns="http://www.w3.org/1999/xhtml" ... >

This was the problem I was running into when serving the xml file from a server.

If unlike me, you are viewing the xml file from a file:/// url, then the solutions mentioning --allow-file-access-from-files are the ones you want

I had the same problem on localhost. Running around the Internet looking for the answer and I approve that adding --allow-file-access-from-files works. I work on Mac, so for me I had to go through terminal sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-file-access-from-files and enter your password (if you have one).

Another small thing - nothing will work unless you add to your .xml file the reference to your .xsl file as follows <?xml-stylesheet type="text/xsl" href="<path to file>"?>. Another small thing I didn't realise immediately - you should be opening your .xml file in browser, no the .xsl.
