CSV 中带有特殊字符的正则表达式和带引号的匹配项
Regular expression with special character inside CSV with quoted matches
我试过了，这是我能想到的最好的，需要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，但我遇到了具有特殊字符 (',") 的匹配项他们。
以下匹配是一个问题，例如：
""SHIPPER'S LOAD & COUNT, SAID TO BE:" 1X20'DC CONTAINER S.T.C 1650 CARTON OF JUICES FREIGHT PREPAID"
(?:^|(?<=,))"(?!,")(.+?)"(?=,"|$)
尝试 this.See 演示。
您的正则表达式（以及要解析的字符串）当前的问题是它不接受值中有引号而字符串有。也许，你可以指定里面可以有一个引号，但是，结束引号只能在逗号之前或字符串的末尾，你可以用正 lookhead 来做到这一点：
".*?"(?=,|$)
".*?" 匹配值，而 (?=,|$) 确保在其后或字符串末尾有一个逗号（由 $ 表示）。
请注意，如果您的字符串的值包含引号后跟逗号，则上述正则表达式将不起作用。
那样的话，我通常做的就是统计匹配的次数。如果这超出了我的预期，我会把原始行分开，这样我就可以一个一个地查看它们（这将涉及一些人工干预，但这总比最终出现很多错误要好！）。
如果所有问题都来自一个列，那么您可以更改您的脚本，使其 'merge' 值从 i 到 j （i 是第一个问题发生的列号，j 是下一个）直到有适当数量的值.
