I\'m having some issues with following regular expressions.
Error: Invalid operation
re := regexp.MustCompile(\"(([a-f0-9]+\\-)+[a-f0-9]+)\\/(.*?)\\/(.*?);version=(\\d*)\")match := re.FindStringSubmatch(hex.EncodeToString([]byte(href)))
fmt.Println(match)
my test strings that I\'m trying to match are
/data/1221a7f47-84c1-445e-a615-ff82d92e2eaa/article/jane;version=1493756861347/data/1221a7f47-84c1-445e-a615-ff82d92e2eaa/article/john;version=1493756856398
Expecting following strings after match

功能建议以下正则表达式存在一些问题。</ p>
错误:无效操作</ p>
</ blockquote>
re:= regexp.MustCompile(“((([a-f0-9] + \\-)+ [ a-f0-9] +)\\ /(。*?)\\ /(。*?); version =(\\ d *)“)
match:= re.FindStringSubmatch(hex.EncodeToString([] byte(href) ))
fmt.Println(match)
</ code> </ pre>
我要匹配的测试字符串是</ p>
/数据/ 1221a7f47-84c1-445e-A615-ff82d92e2eaa /条/简;版本= 1493756861347
\\ N /数据/ 1221a7f47-84c1-445e-A615-ff82d92e2eaa /条/约翰;版本= 1493756856398
</代码 > </ pre>
匹配后期望以下字符串</ p>
- 1221a7f47-84c1-445e-a615-ff82d92e2eaa </ li>
- article </ li>
- jane </ li>
- 1493756856398 </ li>
</ ol>
</ div>
网友观点:
You need to fix the first line, declare the regex correctly. Try these:
Using backslashes (to escape)
re := regexp.MustCompile(\\\"(([a-f0-9]+\\\\-)+[a-f0-9]+)\\\\/(.*?)\\\\/(.*?);version=(\\\\d*)\\\")
Using raw string literals (`)
re := regexp.MustCompile(`(([a-f0-9]+\\-)+[a-f0-9]+)\\/(.*?)\\/(.*?);version=(\\d*)`)
笔记:前端自学基础之正则表达式
转义字符"\\"
多行字符串:
document.body.innerHTML = "\\
<div></div>\\
<span><\\span>\\
";
字符串换行符\\n;行结束:\\r;制表符:\\t(缩进)
正则表达式 RegExp
正则表达式的作用:匹配特殊字符或有特殊搭配原则的字符的最佳选择。 贪婪匹配原则。
两种创建方式:
1、字面量 (推荐) /pattern/attributes
