Constructor Details

#initialize ⇒ Parser

Set up the parser

The default filters do the following:

CSS adds a style block containing boilerplate CSS attributes to be

inlined.  This is based on Email Boilerplate's 'Inline: YES' portions

Premailer passes the email through the Premailer gem, which inlines the CSS

it can, then appends a style block to the body containing the rest (since
some email clients strip out the <head> tag).

Style Element adds another style block, but this one is intended to be left

as a style declaration (rather than being inlined).  This is based on 
EMail Boilerplate's 'Inline: NO' portions

Attributes adds attributes to HTML elements where helpful, such as table cellpadding

and such.  Based on Email Boilerplate's example element declarations

Schema Validation currently just adds the XHTML Strict DTD and outputs to a string,

however it's intended that this will eventually validate against an XSD and emit
warnings about potentially troublesome tags (like <div>)
