WriteXMLDeclaration Method

Writes an XML declaration at the top of the document.

Syntax

xmlw.writeXMLDeclaration(version, includeEncoding, standalone, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method should be call first to write a new XML declaration at the top of the document. Version specifies the XML version to use ('1.0').

If IncludeEncoding is true, an encoding attribute will be included based on the current Charset. If Standalone is true, the standalone="true" attribute will be included on the declaration.
