Given a path of withing a tag provider, how to check using the python script if the node the path defines is a tag and not a folder or an UDT?

Thanks!

Use this:

> **[system.tag.browse | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-tag/system-tag-browse)**
>
> Returns a list of nodes found at the specified path.

Analyse the dictionary it returns for the type.

- typeId - Represents the UDT type of the node. If the node is a UDT definition, then the value will be `None`. If the node is not a UDT, then this filter choice will **not** remove the element. As such, this filter functions best when paired with a tagType filter with a value of UdtInstance.

```python
{"typeId":"myUDT", "tagType":"UdtInstance"}

```

A folder will just give you a list of the tags inside it.

Just use `system.tag.readBlocking()` with the path plus `.tagType`. Simple tags will be `Atomic`.
