提取部分文件并使用python打印

Question

我想提取部分文件内容。以“头”开头 以“arraydat”结尾

文件内容：

(record
  ( "head"
    (record
     ( "pname" "C16D")
     ( "ptype" "probe")
       ( "sn" "11224")
         ( "rev" "1")
          ( "opname" "Kaji")
         ( "comm"
         [ "" ]
        )
      ( "numel" 192)
      ( "mux" 1)
      ( "freq" 3400000)
     ( "date" 63602497416.093)
      ( "focus" 0.066)
      ( "probID" 574)
          ( "te" 0)
     ( "therm" 0)
      ( "bipolar" "N/A")
      ( "maker" "YMS")
     ( "PartNum" 5418916)
       ( "numrow" 1)
       )
      )
     ( "arraydat"
       (record
      ( "FL6" 1625283.947393933)
      ( "FH6" 4932875.254089763)
     ( "FL20" 1283607.261269079)
     ( "FH20" 5673248.882271254)
     ( "Fc" 3279079.600741847)
      ( "BW" 100.8695033187829)
      ( "PW6" 3.316821935120381E-007)
    ( "PW20" 9.740000000000003E-007)
       ( "PW30" 1.456E-006)
       ( "PW40" 2.628000000000001E-006)
       ( "LG" -46.35823409318354)
       ( "TOF" -1.363659434369523E-008)
        )

我需要在“head”之后和“arraydat”之前提取文件的内容。 我试过这个命令，但运气不好

import re
    with open('sample.txt','r') as new_file:
    data = new_file.read()
    pattern = re.compile(r'\s[(]\s"head"[\s\S]*?\s[(]\s"arraydat"')
    stringtext = re.findall(pattern, data)
    print(stringtext)

输出应如下所示：

    ( "pname" "C16D")
  ( "ptype" "probe")
     ( "sn" "11224")
    ( "rev" "1")
   ( "opname" "Kaji")
      ( "comm"
         [ "" ]
        )
      ( "numel" 192)
      ( "mux" 1)
      ( "freq" 3400000)
     ( "date" 63602497416.093)
      ( "focus" 0.066)
      ( "probID" 574)
          ( "te" 0)
     ( "therm" 0)
      ( "bipolar" "N/A")
      ( "maker" "YMS")
     ( "PartNum" 5418916)
       ( "numrow" 1)
       )
     )

Answer 1

data = []
read = False

for line in open('test.dat'):
    if line.strip() == '( "head"':
        read = True
        continue
    elif line.strip() == '( "arraydat"':
        read = False
    if read:
        data.append(line.rstrip())

print('\n'.join(data))
