Yes indeed, the real data often has surprising differences from the
simulations! :)

It turns out that pyparsing LineStart()'s are pretty fussy.  Usually,
pyparsing is very forgiving about whitespace between expressions, but
it turns out that LineStart *must* be followed by the next expression,
with no leading whitespace.

Fortunately, your syntax is really quite forgiving, in that your
key-value pairs appear to always be an unquoted word (for the key) and
a quoted string (for the value).  So you should be able to get this
working just by dropping the LineStart()'s from your expressions, that
is:

identLine=('Identifier'
          + prs.quotedString
          + prs.LineEnd()
          ).setResultsName('prog')


tableLine=('Value'
          + prs.quotedString
          + prs.LineEnd()
          ).setResultsName('table')

See if that works any better for you.
