从文本中提取字符串和数字

Question

我有像10E4558AA0_String1_String2_String3_0_100_12mo这样的字符串。我想提取string1和string2以及0和100。
0_100也可以是0_10，11_25，26_75或76_100，我想提取0 10，{{1}分别是}，11 25，26 75。我认为正则表达式可以工作，但我正在努力编写部分。

Answer 1

通过Split

由于您的字符串由_分隔命令，但这会因语言而异。

Javascript看起来像str.split("_")，可以在rosettacode.org找到更多用于标记字符串的语言示例

通过Regex Matching

要通过正则表达式匹配严格执行此操作，您可以添加一些字符串验证，如下面的正则表达式。

^([0-9a-f]+)_(string[^_]+)_(string[^_]+)_(string[^_]+)_([0-9]+)_([0-9]+)_([^_]+)$

示例文字

10E4558AA0_String1_String2_String3_0_100_12mo

样本匹配

[0][0] = 10E4558AA0_String1_String2_String3_0_100_12mo
[0][1] = 10E4558AA0
[0][2] = String1
[0][3] = String2
[0][4] = String3
[0][5] = 0
[0][6] = 100
[0][7] = 12mo
