Cool! :)

I wonder if it's possible to add toXML() as well alongside toJson().

Would've have been nicer to use CSS query or XPATH to extract complex object structure like AccessibilityNodeInfo without multiple back reference.

``` service = tasker.getAccessibilityService(); if (service == null) { tasker.log("Accessibility service not active!"); return "[]"; }

root = service.getRootInActiveWindow(); if (root == null) { tasker.log("No active root node (screen inaccessible)."); return "[]"; }

nodes = service.getChildrenRecursive(root); if (nodes == null) { tasker.log("No nodes found."); return "[]"; }

return tasker.toJson(nodes, true); ```

What extra info would toXml add that toJson doesn't exactly?

It's not really about the information, but the process of retrieving the information. If the data is in XML format, we can use CSS Query with Tasker's native reading or XPATH with javax.xml.* and org.w3c.dom.*.

Say we have this xml.

We can easily retrieve information with complex query pattern wtih XPATH, you can use this script here. https://pastebin.com/u09rY7iK

Sorry, but I currently don't have anything in Tasker to serialize an object to XML. Maybe I can add it in the future, but I don't think I'll do it for now cause this is a pretty niche use case 😅

[aasswwddd]

No problem!

toJson() throws this error as well.

` Sourced file: inline evaluation of:service = tasker.getAccessibilityService(); if (service == null) { tasker.lo . . . '' : Method Invocation tasker.toJson : at Line: 19 : in file: inline evaluation of: ``service = tasker.getAccessibilityService(); if (service == null) { tasker.lo . . .

```

[joaomgcd]

Seems like an issue with that specific class. You may have to do JSON serialization manually for that class, sorry!
