# XMPP PubSub To Atom
A little client that parses XMPP Pubsub Nodes and sends them as Atom Syndication Format or OPML over HTTP.
## About
XMPP PubSub To Atom ("XPTA") is a simple Python script that parses XMPP Pubsub Nodes and sends them as Atom Syndication Format or OPML over HTTP.
XPTA generates Atom syndication feeds ([RFC 4287](https://www.rfc-editor.org/rfc/rfc4287)) from XMPP PubSub nodes ([XEP-0060](http://xmpp.org/extensions/xep-0060.html)).
This software was inspired from Tigase and was motivated by Movim.

## Requirements
* Python >= 3.5
* fastapi
* feedgenerator
* lxml
* slixmpp
* tomllib
* uvicorn
## Installation
### Debian-based Distro
```shell
# apt install python3 python3-fastapi python3-feedgenerator python3-lxml python3-slixmpp python3-tomli uvicorn
```
### Download
Extract the source package to a directory that you have permission to run
software.
```shell
$ git clone https://git.xmpp-it.net/sch/PubSubToAtom
$ cd PubSubToAtom/

$ python -m uvicorn pubsub_to_atom:app --reload --host 127.0.0.1 --port 8000
$ uvicorn pubsub_to_atom:app --host 127.0.0.1 --port 8000
$ fastapi dev pubsub_to_atom.py
```
## Usage
It is possible to view a complete node and even a single item, which means, that it is possible to save bandwidth and it further means that a considered and carefully earnest use of this software would saves system overhead, which includes CPU, I/O and RAM usage.
### Viewing PubSub
Suppose you have the following nodes and items.
|PubSub |Node |Item |
