Dump a subset of a cmssw pset recursively

dump_pset_subset.py

from pset_rawsim_onlyhlt import process

def recurse_coll(item,already_dumped=[]):
    if hasattr(item,"_seq"):
        print("process.{} = {}\n".format(item.label(),item.dumpPython()))
        for thing in item._seq._collection:
            for x in recurse_coll(thing): yield x

    if type(item) in [tuple]:
        pk,pv = item
        if pv.configTypeName() == "InputTag":
            label = pv.value().split(":",1)[0]
            if hasattr(process,label):
                for x in recurse_coll(getattr(process,label)): yield x
            else:
                yield pk,pv

maincoll = process.ScoutingCaloMuonOutput
_ = list(recurse_coll(maincoll))

Also run edmConfigDump on the pset and copy in the lines like

import FWCore.ParameterSet.Config as cms
process = cms.Process("HLT")

to the beginning of the output of the gist script output. Also make sure the sequence is defined at the bottom (move if necessary). Then you should be able to use edmConfigToHTML.
