Jinja2 Key Value Spliter for Pelican meta data

Jinja Key Value Pair Breakdown

# What I am attempting to do is split each key value pair groups down into smaller key value pairs spliting each at specified characters i.e:("=" "," ":" "|" )..etc. the characters used are arbitrary 
# Example: Markdown metadata looks like this.


Title: Demo Product
date: 9-19-2013
productvariations: Sizes=Small:13.00,Med:33.00,Large:42.00|Colors=Red,Green,Blue


# We need to output the following as:

Sizes:
  Small 13.00
  Med   33.00
  Large 42.00
Colors:
  Red
  Green
  Blue


# My current solution using jinja is this:

{% for variations_groups in article.productvariations.split('|') %}
{% set variation_name = loop.cycle(variations_groups.split('=')) %}
<h2>{{variation_name}}:</h2>
<ul>
{% for variation_items in article.productvariations.split(',') %}
        {% set pairlist = loop.cycle(variation_items.split(':')) %}
       <li> {{pairlist[0]}} {{pairlist[1]}} </li>
{% endfor %}
</ul>
{% endfor %}
