Get BLogger Labels

$label_url = "http://www.blogger.com/feeds/#{$userID}/blogs/#{$blogID}?alt=json-in-script&callback=listLabels"

class BlogLabels

  def get_labels
    result = URLFetch.get($label_url)
  result_headless = result.gsub("listLabels(",'')
  pure_result = result_headless.gsub(");",'')
    JSON.parse(pure_result)['entry']['category']
  end

end

@labels = BlogLabels.new
@labels.get_labels.each do |cont|
 puts cont['term']
end

JSON was not works.
Change to use YAML.

 response = URLFetch.get($label_url)
 result = response.to_s
 result_headless = result.gsub("listLabels(",'')
 pure_result = result_headless.gsub(");",'')
 json_to_yaml = YAML::load(pure_result)['entry']['category']
