Detailed documentation

`format(document)`

Outputs the given Document as a formatted string.

Parameters

Name	Type	Description
`document`	`Document`	the document to format

Return

String — the formatted document

`format(element)`

Outputs the given Element node as a formatted string.

Parameters

Name	Type	Description
`element`	`Element`	the element to format

Return

String — the formatted element

`setEncoding(encoding)`

Sets the character encoding that the formatter should use. The encoding argument must be an accepted XML encoding like ISO-8859-1 , US-ASCII , UTF-8 , or UTF-16 .

// Log an XML document with encoding that does not support certain special characters.
var xml = '<root><a><b>ಠ‿ಠ</b><b>ಠ‿ಠ</b></a></root>';
var document = XmlService.parse(xml);
var output = XmlService.getRawFormat()
    .setEncoding('ISO-8859-1')
    .format(document);
Logger.log(output);

Parameters

Name	Type	Description
`encoding`	`String`	the encoding to use

Return

Format — the formatter, for chaining

`setIndent(indent)`

Sets the string used to indent child nodes relative to their parents. Setting an indent other than null will cause the formatter to insert a line break after every node.

// Log an XML document with each child node indented four spaces.
var xml = '<root><a><b>Text!</b><b>More text!</b></a></root>';
var document = XmlService.parse(xml);
var output = XmlService.getCompactFormat()
    .setIndent('    ')
    .format(document);
Logger.log(output);

Parameters

Name	Type	Description
`indent`	`String`	the indent to use

Return

Format — the formatter, for chaining

`setLineSeparator(separator)`

Sets the string to insert whenever the formatter would normally insert a line break. The three pre-defined formatters have different conditions under which they insert a line break. The default line separator is \r\n .

// Log an XML document with several spaces and a pipe character in place of line breaks.
var xml = '<root><a><b>Text!</b><b>More text!</b></a></root>';
var document = XmlService.parse(xml);
var output = XmlService.getRawFormat()
    .setLineSeparator(' | ')
    .format(document);
Logger.log(output);

Parameters

Name	Type	Description
`separator`	`String`	the separator to use

Return

Format — the formatter, for chaining

`setOmitDeclaration(omitDeclaration)`

Sets whether the formatter should omit the XML declaration, such as <?xml version="1.0" encoding="UTF-8"?> .

Parameters
