When Oxygen XML Editor formats and indents XML documents, a whitespace normalization process is applied, thus replacing whitespace sequences with single space characters. Oxygen XML Editor allows you to configure which Unicode characters are treated as spaces during the normalization process.
To configure the Whitespace preferences, open the Preferences dialog box and go to .
This table lists the Unicode whitespace characters. Check any that you want to have treated as whitespace when formatting and indenting an XML document.
