Python Regex to match YAML Front Matter

Question

I\'m having trouble crafting a regex to match YAML Front Matter

This is the front matter I was trying to match:

    ---
    name: me
    title: test

I've used something like this regex, re.findall('^---[\s\S]+?---', text):

def extractFrontMatter(markdown):
    md = open(markdown, 'r')
    text = md.read()
    md.close()
    # Returns first yaml content, `--- yaml frontmatter ---` from the .md file

    # https://stackoverflow.com/questions/2503413/regular-expression-to-stop-at-first-match
    match = re.findall('^---[\s\S]+?---', text)
    if match:
        # Strips `---` to create a valid yaml object
        ymd = match[0].replace('---', '')
        try:
            return yaml.load(ymd)
        except yaml.YAMLError as exc:
            print exc

I've also come across python-frontmatter, which has some additional helper functions:

import frontmatter
post = frontmatter.load('/path/to-markdown.md')

print post.metadata, 'meta'
print post.keys(), 'keys'
