# scheduleCommandXML Method

The earliest versions of the API operated by passing XML documents around, and that method is still available through the `scheduleCommandXml` function. For example, this is how to call `readTitle`.

```javascript
let s = ServiceHandler.scheduler;
s.scheduleCommandXml(
  '<newblue_ext command="readTitle" channel="-1" input="API Tour: JSON Command Tester" />',
  callback
);

// or when using promises ...
await s.scheduleCommandXml('<newblue_ext command="readTitle" channel="-1" input="API Tour: JSON Command Tester" />');

// is essentially equivalent to this:
await s.scheduleCommand('readTitle', { channel: -1, input: 'API Tour: JSON Command Tester' }, {});
```

The xml document should be constructed with a root node named `newblue_ext` with parameters specified as attributes on the node, and variables specified as child nodes if relevant to the command.

Captivate will respond by passing the following XML to the callback function:

```xml
<newblue_ext command="readTitle" reply="readTitle" success="1">
    <title position="4" ready="1" name="Carbon Basketball Scoreboard" input="Shared: Objects,API Tour: JSON Command Tester" id="{05930c36-bd6d-4350-80cd-f58b476fbde9}" function="" inputActive="1" selected="0">

        <variables>
            <variable name="Clock 1" value="00:00" varType="128" dataType="text" dynamic="1" input="" show="1" />
            <variable name="Clock 2" value="0" varType="128" dataType="text" dynamic="1" input="" show="1" />
            <variable name="Home Score" value="0" varType="128" dataType="text" dynamic="1" input="" show="1" />

            <variable name="Scale" value="1,1" varType="0" dataType="scale" dynamic="0" input="" />
        </variables>
    </title>
</newblue_ext>
```

Notice that the reported `inputName` has all connected inputs separated by a comma.
