Hey @acdacd2, please use proper Markdown when posting code. It really isn’t that hard to do and it makes it so much easier and pleasant for others to read, and possibly find errors quicker. Specifically you need to use back ticks before and after your code:

     ```
     like so. Note that a back tick is not the same as the normal apostrophe, ` versus ' .
     ```

@KirAsh4 can you confirm MM startup with my module with this config file?

The module won’t show any results but MM should boot?

KirAsh4

The file ‘status.xml’ doesn’t exist on my system, so it gets a 404 returned, however it does load up, and it does work.

I have the same message with my environment.
In a browse it’s ok

KirAsh4

Right, I have not tested this on an actual rpi … I’m at the office, so I’m running a serveronly setup. I can do an rpi test later, although I suspect it will still work, as opposed to resulting in a blank screen. It returns the error as expected when it can’t find the file.

acdacd2

with a browser on the pi, it’s also ok

@KirAsh4 I’ve isolated the issue as a Cross-Domain Access issue. Do you know of any particular way to make XMLHTTPRequests to external domains?

I wasn’t aware this would be an issue but apparently anybody who wants to use this and map to an external domain will have this issue unless they have a running PHP server that can store the XML results locally (or if they can access a server, they can add the line Access-Control-Allow-Origin: * to their HTML headers.

Any ideas?

KirAsh4

XMLHTTPRequest. Look at how the 'currentweather' module does it in the 'updateWeather()' function.

Yeah that’s what I based my original request functionality on. The OpenWeather API response is CORS compatible due to the response header - this is why the example response works well. Outside of this domain though (say on http://www.w3schools.com/xml/cd_catalog.xml (or any other external server). This unfortunately makes problems - I’m still looking for a work-around.

I’m using that code in php

$xml = simplexml_load_file('XML/status1.xml');
echo "<br>--------------<br>XML parsing <br>--------------<br>";
$result = array();

foreach($xml->children() as $child){
$result[$child->getName()] = trim($child);

have a look in here https://forum.magicmirror.builders/topic/240/soccer-standings i had also problems with cors so i used the request module in my node_helper to fix it

acdacd2

I copied the xml file on a synology web server, same behaviour status :0

Thanks @strawberry-3-141 - I’ll take a look and see if there are any changes I can make.

@KirAsh4

I’m having this same error with a module… What am I doing wrong… any hints much appreciated

KirAsh4

Does that module actually require an 'npm install' to be run? Don’t blindly run commands that you don’t know are actually necessary. You need to ask the author of that module how to properly install it, what the steps are, what’s needed, etc., etc. I know nothing of that module.

Edited to add: running an 'npm install' is generally only required if the specific module needs any additional node dependencies installed. However, the author would make this known. If it doesn’t say that anywhere, do not assume you have to do it yourself. You may end up causing more harm to your installation than good.
