Dashboards & Visualizations

Debugging Advanced XML

Explorer

I'm building my first Advanced XML dashboard and need some guidance.

I'm using Notepad++ to build my dashboard and then copying it into a new view. But when I try to save the view I get this error at the top of the page: Encountered the following error while trying to update: In handler 'views': Not valid XML:

Not really helpful for debugging since it doesn't tell me where the syntax error is in my xml.

I looked in /opt/splunk/var/log/splunk but don't see anything that's logging my error.

Just wondering how to troubleshoot my error and best practices for building advanced XML dashboards.

Thanks

Nick's thoughts are excellent. I've also used the XML Validator at w3schools when on a vanilla Windows® box.

The best advice I can give is to spend some time keeping your indentation clean.

I believe Notepad++ has a preview mode where you can preview the file in a local browser, and the browser will tell you what tags didnt match, and it's much faster than using Splunk itself to check for well-formedness.

And if you're on a linux or unix system, tidy can be a very useful tool:

tidy -i -m -xml my_view.xml

OR

tidy -i -xml my_view.xml -f cleaned_up_version.xml

If your XML is already valid, those will go through and clean up and normalize all your indentation for you. And I think if you do have typos or missing closing tags, tidy can tell you what and where they are.
