parsing - Setup -match statement -


i'm trying setup -match statement based on number of conditions.

these conditions: lines contain holiday date follow these rules.

  • they contain text "title", followed by
  • one or more of character, followed by
  • the text "when: " (note trailing space), followed by
  • three "word" characters , space, followed by
  • the date in "dd mmm yyyy" format (i.e., "31 dec 2012”), followed by
  • a character not space, "word" or "digit"

the characters match underlined bullet point ones need extracted, converted [datetime] value, , returned caller.

a sample of data based on holiday dates. focus line in bold.

<br />event status: confirmedhttp://www.google.com/calendar/event?eid=mjaxntaymtrfnjbvmzbkcjq2c28zmgmxzzywbzmwzhi0y28gdxnhx19lbkbo' title='alternate'/>http://www.google.com/calendar/feeds/usa__en%40holiday.calendar.google.com/public/basic/20150214_60o30dr46so30c1g60o30dr4co'/>holidays in united stateshttp://www.google.com/calendar/feeds/usa__en%40holiday.calendar.google.com/public/basic/20140214_60o30dr46so30c1g60o30dr4ck2014-03-24t19:02:40.000z2014-03-24t19:02:40.000zhttp://schemas.google.com/g/2005#kind' term='http://schemas.google.com/g/2005#event'/>valentine&#39;s daywhen: fri 14 feb 2014<br><br>who: holidays in united states

this have far: 'title.*when:\s+(\w{1,3})\s(?<date>)(?\s\w\d)'

i error:

parsing "title.*when:\s+(\w{1,3})\s(?<date>)(?\s\w\d)" - unrecognized grouping construct. @ d:\test.ps1:9 char:8 + if ( $_ -match 'title.*when:\s+(\w{1,3})\s(?<date>)(?\s\w\d)') + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + categoryinfo : operationstopped: (:) [], argumentexception + fullyqualifiederrorid : system.argumentexception

what have done wrong?

i think went off rails here:

(?<date>)(?\s\w\d)

a named group construct (? followed regex , closing paren:

(?<date>?\s\w\d)
