我有下面这段字符串

text := 59-1124043-1053 - FLOATING JOINT4PC15-Feb-2020 Purchase PriceUSD 28.00112.00per 1 PCTaxable: N Resale: N<70.000KG DHL Express - Intl Shpts 962183650SCAC1:DHLCOver70.000KG Agility Logistics - Export StandardSCAC2:AGYC3 59-1124043-1055 - UNDER RAIL1PC15-Feb-2020 Purchase PriceUSD 138.00138.00per 1 PCTaxable: N Resale: N<70.000KG DHL Express - Intl Shpts 962183650SCAC1:DHLCOver70.000KG Agility Logistics - Export StandardSCAC2:AGYC4 59-1124043-1056 - UPPER RAIL1PC15-Feb-2020

通过正则规则

PNExprV2 = [^(-138)][\d]+-.*[\d][\s]+.*[\d]{1}[a-zA-Z]{2}[\d]{2}-[a-zA-Z]{3}-[\d]{4}

PNParser := regexp.MustCompile(PNExprV2)

line1 := PNParser.FindAllStringSubmatch(c, 10)

匹配出来的还是原字符串期待匹配结果是 ["59-1124043-1053 - FLOATING JOINT4PC15-Feb-2020", ..., "59-1124043-1056 - UPPER RAIL1PC15-Feb-2020"]

请大佬们帮忙看看

延申一下
如果字串是
text := "611-0571271-20126 8PC03-Feb-2020DEBURR INSERTMaterial revision level: A Purchase PriceUSD 14.00112.00per 1 PCTaxable: N Resale: NRFQ# 170593<70.000KG DHL Express - Intl Shpts 962183650SCAC1:DHLCOver70.000KG Agility Logistics - Export StandardSCAC2:AGYC711-0571337-21531 5PC03-Feb-2020U-ING PUNCHMaterial revision level: B Purchase PriceUSD 41.00205.00per 1 PCTaxable: N Resale: NRFQ# 170593<70.000KG DHL Express - Intl Shpts 962183650SCAC1:DHLCOver70.000KG Agility Logistics - Export StandardSCAC2:AGYC811-0571378-5147B 7PC03-Feb-2020"

还想匹配到 ["611-0571271-20126 8PC03-Feb-2020", ..., "811-0571378-5147B 7PC03-Feb-2020"] 这样呢
有没有通用的

谢谢大佬们

.*就已经匹配完了后面的所有字符串。
[^(-138)][\d]+-[\d]+-[\d]+\s-\s[a-zA-Z]+\s[a-zA-Z0-9]+-[a-zA-Z]+-[\d]+
这个能匹配出来，但是我也是个菜鸟，还是等大佬的吧。

有什么特殊要求么?
[^(-138)] 看起来你想不以 -, 1, 3, 8 开头? 那么不需要括号, 直接 [^-138] 就好. 除非你是想不以整个 -138 开头.
其他方便好像没看出什么来.
简单的话就 "\d+-\d+-\d+ - \w+ \w+-\w{3}-\d{4}"

PS: 不要滥用 .*

"\d+-\d+-\w+( - \w+)? \w+-\w{3}-\d{4}"

"611-0571271-20126 8PC03-Feb-2020" 这个字符串中间没有之前 "59-1124043-1053 - FLOATING JOINT4PC15-Feb-2020" 中的 " - FLOATING" 改成可选的就行.
然后 "811-0571378-5147B 7PC03-Feb-2020" 中的 "5147B" 出现了字母, 用字符匹配.

推荐一下 <regular expression> 这本书. 简单的话 <正则表达式必知必会> 就几十页, 上班通勤就完全搞定. 基本上大多简单的问题都能解决.
