我第一次尝试使用pyparsing。我的解析器没有做我希望它做的事情,有人可以检查一下,看看有什么问题。我正在尝试将 OneOrMore 嵌入 OneOrMore 中,我认为它应该可以正常工作,但事实并非如此。
下面是整个代码:
import pyparsing
status = """
sale number : 11/7
NAME ID PAWN PRICE TIME %C STATE START/STOP
cross-cu-1 1055 1 106284K 07:49:36.19 25.05% run 1d01h
cross-cu-2 918 1 104708K 07:38:19.08 24.02% run 1d01h
sale number : 11/8
NAME ID PAWN PRICE TIME %C STATE START/STOP
cross-cu-3 1055 1 106284K 07:49:36.19 25.05% run 1d01h
cross-cu-4 918 1 104708K 07:38:19.08 24.02% run 1d01h
"""
integer = pyparsing.Word(pyparsing.nums).setParseAction(lambda toks: int(toks[0]))
decimal = pyparsing.Word(pyparsing.nums + ".").setParseAction(lambda toks: float(toks[0]))
wordSuppress = pyparsing.Suppress(pyparsing.Word(pyparsing.alphas))
endOfLine = pyparsing.LineEnd().suppress()
colon = pyparsing.Suppress(":")
saleNumber = pyparsing.Regex("\d{2}\/\d{1}").setResultsName("saleNumber")
lineSuppress = pyparsing.Regex("NAME.*STOP") + endOfLine
saleRow = wordSuppress + wordSuppress + colon + saleNumber + endOfLine
name = pyparsing.Regex("cross-cu-\d").setResultsName("name")
id = integer.setResultsName("id")
pawn = integer.setResultsName("pawn")
price = integer.setResultsName("price") + "K"
time = pyparsing.Regex("\d{2}:\d{2}:\d{2}.\d{2}").setResultsName("time")
c = decimal.setResultsName("c") + "%"
state = pyparsing.Word(pyparsing.alphas).setResultsName("state")
startStop = pyparsing.Word(pyparsing.alphanums).setResultsName("startStop")
row = name + id + pawn + price + time + c + state + startStop + endOfLine
table = pyparsing.OneOrMore(pyparsing.Group(saleRow + lineSuppress.suppress() + (pyparsing.OneOrMore(pyparsing.Group(row) | pyparsing.SkipTo(row).suppress())) ) | pyparsing.SkipTo(saleRow).suppress())
resultDic = [x.asDict() for x in table.parseString(status)]
print resultDic
它只返回 [{'saleNumber': '11/7'}]
我希望得到这样的 dic 列表:
[{ {'saleNumber': '11/7'},{ elements in cross-cu-1 line, elements in cross-cu-2 line } },
{ {'saleNumber': '11/8'},{ elements in cross-cu-3 line, elements in cross-cu-4 line } }]
任何帮助表示赞赏! 请不要建议其他实现此输出的方法!我也在努力学习 pyparsing!
