IndentHTML
IndentHTML makes your (X)HTML source code look “nicer”. Since this class generates easy readable output, it’s the straight opposite of TrimHTML. Note that the source code should be well-formed according to the rules of XML, because the class does not include a SGML parser.
IndentHTML.php
The constructor takes one optional string argument in order to customize the indent char(s). Sensible values are blanks and "\t", two blanks are used by default.
Requires: Preprocess
