All Implemented Interfaces:
Compressor
```
public class HtmlCompressor
extends java.lang.Object
implements Compressor
```
Class that compresses given HTML source by removing comments, extra spaces and line breaks while preserving content within <pre>, <textarea>, <script> and <style> tags.
Blocks that should be additionally preserved could be marked with:

or any number of user defined patterns.
Content inside <script> or <style> tags could be optionally compressed using Yahoo YUI Compressor or Google Closure Compiler libraries.
