这是从 CSV 导入的一行原始文本:
10,"2013-04-17 16:29:36",out,"BTC sold: [tid:0450750450454505] 0.85985758 BTC at 69.88355 € (0.55% fee)",0.85985758,0
我要编辑的代码相当简单,来自[本教程页面][1](*主代码副本在本页底部):
主要的正则表达式代码部分是:
var objPattern = new RegExp(
(
// Delimiters.
"(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +
// Quoted fields.
"(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +
// Standard fields.
"([^\"\\" + strDelimiter + "\\r\\n]*))"
),
"gi"
);
我想要的是,在我在开头复制的原始行文本中,我想删除或忽略括号、括号 () 之间的内容,并使“at”这个词成为新列的分隔符。当我导入 CSV 时,新列的值将是单词“at”之后的值。
等效的正则表达式代码应为: [(. ?)]|(((. ?)) 和 (\bat\b)
我尝试了各种选项,例如将 (\bat\b) 添加到分隔符部分的正则表达式,但它不起作用。
非常感谢您的帮助!
