I am creating a script which need to parse the yaml output that the puppet outputs.

When I does a request agains example https://puppet:8140/production/catalog/my.testserver.no I will get some yaml back that looks something like:

--- &id001 !ruby/object:Puppet::Resource::Catalog
  aliases: {}
  applying: false
  classes: 
    - s_baseconfig
    ...
  edges: 
    - &id111 !ruby/object:Puppet::Relationship
      source: &id047 !ruby/object:Puppet::Resource
        catalog: *id001
        exported:

and so on... The problem is when I do an yaml.load(yamlstream), I will get an error like:

yaml.constructor.ConstructorError: could not determine a constructor for the tag '!ruby/object:Puppet::Resource::Catalog'
 in "<string>", line 1, column 5:
   --- &id001 !ruby/object:Puppet::Reso ... 
       ^

As far as I know, this &id001 part is supported in yaml.

Is there any way around this? Can I tell the yaml parser to ignore them? I only need a couple of lines from the yaml stream, maybe regex is my friend here? Anyone done any yaml cleanup regexes before?

You can get the yaml output with curl like:

curl --cert /var/lib/puppet/ssl/certs/$(hostname).pem --key /var/lib/puppet/ssl/private_keys/$(hostname).pem --cacert /var/lib/puppet/ssl/certs/ca.pem -H 'Accept: yaml' https://puppet:8140/production/catalog/$(hostname)

I also found some info about this in the puppet mailinglist @ http://www.mail-archive.com/puppet-users@googlegroups.com/msg24143.html. But I cant get it to work correctly...

python yaml puppet
