indent expression

If the value of expression is 1, saved and listed XML will be formatted using some (hopefully) ignorable whitespace. If the value is 2 (or higher), XSH2 will act as in case of 1, plus it will add a leading and a trailing linebreak to each text node.

Note, that since the underlying C library (libxml2) uses a hard-coded indentation of 2 space characters per indentation level, the amount of whitespace used for indentation can not be altered at runtime.

This command is equivalent to setting the $INDENT variable.
