BBEdit Grep/Regex 查找并替换破折号后的部分

BBEdit Grep/Regex find and replace part after dash

当我想查找并删除文章编号列中以破折号 (-) 开头的部分以及后面的所有内容时,正则表达式应该是什么样子?

我正在使用 BBEdit 搜索和替换制表符分隔的 CSV 文件(示例如下)中的字符串。

"Article number"    "Name"  "Third Column"
"Shorts Artic"  "Swa..."    "2018-07-28"
"Shorts Artic-1"    "Swa..."    ""
"Shorts Artic-2-1"  "Swa..."    "https://test-domain.com/..."
"Shorts Artic-2-2-1"    "Sw..." ""
"Shorts Artic-2-2-2-2-1"    "Ba..." "-asd"
"Shorts Artic-2-2-2-2-2-1"  "Nus..."
"Shorts Artic-2-2-2-2-2-1-1"    "Lek.."
"0858-1"    "Jacket Blue.."
"0858-2-1"  "Jacket Re.."
"0858-2-2-1"    "Int..."
"0858-2-2-2-1"  "In..."
"0858-2-2-2-2-1"    "Int..."
"0858-2-2-2-2-2-1"  "Int..."
"0858-2-2-2-2-2-2-1"    "Int..."
"0858-2-2-2-2-2-2-2-1"  "In..."
"0858-2-2-2-2-2-2-2-2"  "In..."
"0858-2-2-2-2-2-2-2-1"  "In..." "6 107-124 cm"
"stl 31-35-1-1-1-1-2-2-2-1-1"   "In..."

"Shorts Artic-1" 会变成 "Shorts Artic"

"Shorts Artic-2-2-1" 会变成 "Shorts Artic"

"0858-2-2-2-2-2-2-2-2" 会变成 "0858"

你可以使用这个模式:

("[a-zA-Z 0-9]+)(?:-\d)+(?=")
  • ("[a-zA-Z 0-9]+) 匹配并捕获 "、字母字符、空格和数字。
  • (?:-\d)+ 非捕获组。重复匹配并捕获 - 和数字。
  • (?=") " 的积极前瞻。

替换为:

对于更新后的文本文件,您可以使用:

^"((?:[a-zA-z]+ ?)+|[0-9]+)(?:-?\d)+(?=")

替换为:

"
