Re: [Pyparsing] Anchoring py.Regex

[thomas_h <th...@gm...>]

Any update on this?

To summarize, I wonder why this (character after start-of-line, with
optional intervening whitespace, in a multi-line match)

  py.Regex(r'^\s*B', re.M).searchString('foo\nB')

matches, while this

  py.Regex(r'^\s*B', re.M).searchString('foo\n B')

doesn't (mind the space between '\n' and 'B' in the search string),

while these two ('o' before end-of-line, with optional intervening
whitespace, in a multi-line match)

  py.Regex(r'o\s*$', re.M).searchString('foo\nB')
  py.Regex(r'o\s*$', re.M).searchString('foo \nB')

both match (capturing the whitespace in the second case). Why do the ^
and $ anchors behave differently?

Thanks,
Thomas
