在两组字符之间获取单词

Question

我正在尝试编写一个正则表达式，在这两组字符之间取任何字：
3D 和 &sa

实施例：

3D Evb31p5vFs4_ ＆amp; sa ：输出：Evb31p5vFs4_

3D _Ve8_LBztG50_ ＆amp; sa ：输出：_Ve8_LBztG50_

我使用了表达式：/\w[3D][A-Za-z0-9_-].*sa/g
所以下一步是跳过“3D”和“＆amp; sa”

提前致谢！

Answer 1

您可以将 match() 与正则表达式 pygame.draw.rect(display, black, [50,leady,15,15])

一起使用

/3D(.*)&sa/

<强>解释

var a='3DEvb31p5vFs4_&sa';
var b='3D_Ve8_LBztG50_&sa' ;

document.write(a.match(/3D(.*)&sa/)[1] +'<br>');
document.write(b.match(/3D(.*)&sa/)[1]);

Answer 2

试试这个：

3D(?s)(.*)&sa

阐释：

3D matches the characters 3D literally (case sensitive)
(?s) Match the remainder of the pattern with the following options:
s modifier: single line. Dot matches newline characters
1st Capturing group (.*)
.* matches any character
Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy]
&sa matches the characters &sa literally (case sensitive)
g modifier: global. All matches (don't return on first match)
