}
```

```java
Bridge xmppclient:xmppBridge:xmpp "XMPP Client" [ host="xmpp.example.com", port=7222, username="openhab", domain="example.com", password="********" ] {
  Channels:
    Trigger String : xmpp_command [ separator="##" ]
}
```

## Example Rules

Send message:

```java
rule "Leak detected"
when
    Item Xi_Leak changed
then
    if(Xi_Leak.state == ON) {
        val actions = getActions("xmppclient","xmppclient:xmppBridge:xmpp")
        actions.publishXMPP("pavel@example.com","Warning! Leak detected!")
    }
end
```

Receive and process message:

```java
rule "Turn off all lights without separator"
when
    Channel "xmppclient:xmppBridge:xmpp:xmpp_command" triggered
then
    var actionName = receivedEvent
    if(actionName.toLowerCase() == "turn off lights") {
        Group_Light_Home_All.sendCommand(OFF)
    }
end

rule "Turn off all lights with separator and reply"
when
    Channel "xmppclient:xmppBridge:xmpp:xmpp_command" triggered
then
    var actionName = receivedEvent.split("##")
    if(actionName.get(1).toLowerCase() == "turn off lights") {
        Group_Light_Home_All.sendCommand(OFF)

        val actions = getActions("xmppclient","xmppclient:xmppBridge:xmpp")
        actions.publishXMPP(actionName.get(0),"All lights was turned off")
    }
end
```
