[Pyparsing] help with delimitedList

[Adam L. <ad...@su...>]

Having a hard time getting to grips with pyparsing, especially as 
related to syslog parsing.

Using the following line as a sample, how would you parse the delimited 
list of key=value pairs?  I've got the date/time, hostname, syslog tag 
parts without problem but I'm unsure how to use the delimitedList operator.

I'm using the following:

equals = Literal('=').setName('equals')
key_value = Word(printables) + equals + Word(printables)
delimitedList(OneOrMore(key_value)) + Optional(Word(printables))

I get the following error:

Expected equals (at char 104), (line:1, col:105)
