我有以下字符串的文本：

{whatever}:::duplicateString:::{whatever}
{whatever}:::duplicateString:::{whatever}
....
{whatever}:::duplicateString:::{whatever}
{whatever}:::duplicateString:::{whatever}

如何从文本中删除重复字符串：主要思想是从行中删除第二个单词，如果它出现超过一次。

第一个想法是逐行读取它们并用“ ::: ”分割，以便创建数组并通过向 TreeSet 添加条目来迭代数组。好的。但是如何再次粘合线呢？

我不记得有任何机制来解决这样的任务。语言无关紧要，只是近似解决方案？

示例文本：

Appliances:::Main
Appliances:::Main:::Appliance Warranties
Appliances:::Main:::Beer Keg Refrigerators
Appliances:::Main:::Beverage Refrigerators
Appliances:::Main:::Ceiling Fans & Accessories
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Downrod Couplers
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Downrods
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Fan Replacement Blades

理想情况下，它必须像：

Appliances:::Main
Appliances:::Appliance Warranties
Appliances:::Beer Keg Refrigerators
Appliances:::Beverage Refrigerators
Appliances:::Ceiling Fans & Accessories
Appliances:::Ceiling Fans & Accessories:::Accessories
Appliances:::Ceiling Fans & Accessories:::Accessories:::Downrod Couplers
Appliances:::Ceiling Fans & Accessories:::Accessories:::Downrods
Appliances:::Ceiling Fans & Accessories:::Accessories:::Fan Replacement Blades

如果 duplicateString 可能仅作为第二个单词出现，您可以（在 Python 中）：

lastWord = None
for line in open('file.txt'):
  w = line.split(':::')
  thisWord = w[1]
  if lastWord==w[1]:
    del w[1]
  lastWord = thisWord
  print ':::'.join(w)
