# DocumentBuilder.IsLineNumbering Property

Determines whether line numbering is enabled for documents loaded using this `DocumentBuilder`.

public bool IsLineNumbering {get; set;}

#### Remarks

By default, line numbering is disabled.

Line numbering is not available for all kinds of source: in particular, it is not available when loading from an existing XmlDocument.

The resulting line numbers are accessible to applications using the extension function saxon:line-number() applied to a node.

Line numbers are maintained only for element nodes; the line number returned for any other node will be that of the most recent element.
