Question

我试过，这是我能想到的最好的，需要一个新的眼光或帮助完成这项工作。

表达式：

\"[a-zA-Z\s0-9\.\']*\"

输入字符串数据：

BOL,"AWBH0876356","HMM","H0010","BEANR","BEANR","AEJEA","BHBAH","","","T","S","","","F","N","","FCL/FCL","BE","","","","","","","","SUNNYLAND DISTRIBUTION NV","EVERDONGENLAAN 12 2300 TURNHOUT","","","INTERNATIONAL AGENCIES CO LTD","BUILDING 406, ROAD 4308, BLOCK 343, MANAMA BAHRAIN","","INTERNATIONAL AGENCIES CO LTD","BUILDING 406, ROAD 4308, BLOCK 343, MANAMA BAHRAIN","","","","","","","N/A","770000",""SHIPPER'S LOAD & COUNT, SAID TO BE:" 1X20'DC CONTAINER S.T.C 1650 CARTON OF JUICES FREIGHT PREPAID","1650","CARTONS","CTN","","","1","1","2.2","21615.0","23815.0","0","0","0","0","","",""

我需要忽略第一个单词（BOL）和逗号，这是有效的，但我仍然坚持使用具有特殊字符（'，"）的匹配。

匹配是一个问题，例如：

""SHIPPER'S LOAD & COUNT, SAID TO BE:" 1X20'DC CONTAINER S.T.C 1650 CARTON OF JUICES FREIGHT PREPAID"

Answer 1

你的正则表达式（以及要解析的字符串）的当前问题是它不接受值内有引号并且字符串有。也许，您可以指定内部可以有引号，但是，结束引号应该只在逗号之前或在字符串的结尾处，并且您可以使用正面看起来：

".*?"(?=,|$)

".*?"匹配值，(?=,|$)确保其后面有逗号或字符串结尾（由$表示）。

请注意，如果您的字符串的值包含引号字符后跟逗号，则上述正则表达式无法正常工作。

在这种情况下，我通常做的是计算匹配数。如果这超过了我期望的数字，我会单独放置原始行，这样我就可以逐个查看它们（这将涉及一些人工干预，但这比最终出现大量错误更好！）。

如果所有问题都来自单个列，那么您可以更改脚本以便它可以合并＆＃39;从 i 到 j 的值（ i 是第一个问题发生的列号， j 是下一个问题的列号），直到有适当数量的值。

(?:^|(?<=,))"(?!,")(.+?)"(?=,"|$)

试试这个。看看演示。
