This little bit of jQuery strips out all the unwanted code from the Campaign Monitor email and enables me to quickly add the email as a blog post.

WDW-Email-Stripper.js

var output = '';

$('.contentblock').each(function(){

	var heading = $(this).find('h2').text();

	var article_heading_h3 = $(this).find('h3 a').text();
	var article_heading_h3_link = $(this).find('h3 a').attr('href');

	var article_heading_h4 = $(this).find('h4 p a').text();
	var article_heading_h4_link = $(this).find('h4 p a').attr('href');

	var article_desc = $(this).find('h3').next('p').text();

	if(heading){
		heading = '<h2>' + heading + '</h2>' ;
		output += heading;
	}

	if(article_heading_h3){
		article_heading_h3 = '<h3><a href="'+article_heading_h3_link+'">' + article_heading_h3 + '</a></h3>';
		output += article_heading_h3
	}

	if(article_heading_h4){
		article_heading_h4 = '<h4><a href="'+article_heading_h4_link+'">' + article_heading_h4 + '</a></h4>';
		output += article_heading_h4
	}

	if(article_desc){
		article_desc = '<p>' + article_desc + '</p>';
		output += article_desc;
	}



});

console.log(output);
