4 years ago Hi,
This
from ttp import ttp
from pprint import pprint
data = """
# show service
Name Protocol Dst-Port/Type
DISCARD UDP 9
DNS UDP 53
TCP 53
ECHO UDP 7
"""
template1 = """
<group method="table" record="name" set="name">
{{ ignore("\s+") }}{{ name }} {{ protocols }} {{ ports | DIGIT }}
{{ ignore("\s+") }} {{ protocols }} {{ ports | DIGIT }}
</group>
"""
parser = ttp(data, template1)
parser.parse()
pprint(parser.result(structure="flat_list"))
# prints:
# [{'name': 'DISCARD', 'ports': '9', 'protocols': 'UDP'},
# {'name': 'DNS', 'ports': '53', 'protocols': 'UDP'},
# {'name': 'DNS', 'ports': '53', 'protocols': 'TCP'},
# {'name': 'ECHO', 'ports': '7', 'protocols': 'UDP'}]How it works:
- group
method="table"tells that each template line is a start line and matches for it should be saved to results - group
record="name"function tells to store value ofnamematch in cache - group
set="name"function tells to retrieve value ofnamevariable from cache and add it to matches that does not have it {{ ignore("\s+") }}- helps to ignore indentation
Or use this if you decide to go with a bit more hierarchy:
template2 = """
<template name="services" results="per_template">
<group name="{{ name }}.{{ proto }}" method="table">
{{ ignore("\s+") }}{{ name }} {{ proto }} {{ port | DIGIT }}
{{ ignore("\s+") }} {{ proto }} {{ port | DIGIT }}
</group>
</template>
"""
parser = ttp(data, template2)
parser.parse()
pprint(parser.result(structure="dictionary"))
# prints:
# {'services': {'DISCARD': {'UDP': {'port': '9'}},
# 'DNS': {'TCP': {'port': '53'}, 'UDP': {'port': '53'}},
# 'ECHO': {'UDP': {'port': '7'}}}}for last example to work need to use latest code from master branch though

how can I get json as: [ {"Name": "DISCARD","Protocol":"UDP","Port":9}, {"Name": "DNS","Protocol":"UDP","Port":53}, {"Name": "DNS","Protocol":"TCP","Port":53}, {"Name": "ECHO","Protocol":"UDP","Port":7} ] without missing DNS TCP 53 ??
