Perfecting a regular expression can take a lot of time and testing but once achieved can be a absolutely golden. While looking through the source code of I stumbled upon a few code-parsing regular expressions that you might be interested in.

完善正则表达式可能会花费大量时间和测试，但一旦实现则绝对是黄金。 在浏览的源代码时，我偶然发现了一些您可能感兴趣的代码解析正则表达式。

JavaScript (The JavaScript)

// Matches a C style single-line comment.	slashComments: /(?:^|[^\\])\/\/.*$/gm,		// Matches a Perl style single-line comment.	poundComments: /#.*$/gm,		// Matches a C style multi-line comment.	multiComments: /\/\*[\s\S]*?\*\//gm,		// Matches a string enclosed by single quotes.	aposStrings:   /'[^'\\]*(?:\\.[^'\\]*)*'/gm, 		// Matches a string enclosed by double quotes.	quotedStrings: /"[^"\\]*(?:\\.[^"\\]*)*"/gm, 		// Matches both.	strings:       /'[^'\\]*(?:\\.[^'\\]*)*'|"[^"\\]*(?:\\.[^"\\]*)*"/gm,		// Matches a property: .property style.	properties:    /\.([\w]+)\s*/gi,   		// Matches a method call: .methodName() style.	methodCalls:   /\.([\w]+)\s*\(/gm, 		// Matches a function call: functionName() style.	functionCalls: /\b([\w]+)\s*\(/gm,   		// Matches any of the common brackets.	brackets:      /\{|\}|\(|\)|\[|\]/g, 		// Matches integers, decimals, hexadecimals.	numbers:       /\b((?:(\d+)?\.)?[0-9]+|0x[0-9A-F]+)\b/gi

Regular expressions can look heinous so I apologize to anyone whose brains imploded after looking at the above hieroglyphics text. Have useful regular expressions you use often? Share them!

正则表达式可能看起来令人发指，因此，对上述象形文字阅读后大脑崩溃的人，我深表歉意。 您是否经常使用有用的正则表达式？ 分享他们！
