输出特定字符串ruby之间的所有内容

Question

我在文件中有一行结构如下：

<IncludePath>..\..\somethingB\include;..\..\..\somethingA\Source;$(IncludePath)<\IncludePath>

我只是想在IncludePath＆gt;之间打印所有内容。和$（IncludePath）

line.scan(/<IncludePath>(.*)$(IncludePath)/m)
print line

但是我和标签一起得到完整的一行。我想只是标签之间的字符串。我做错了什么？

Answer 1

尝试：

> string = "<IncludePath>..\..\somethingB\include;..\..\..\somethingA\Source;$(IncludePath)<\IncludePath>"
> string[/<IncludePath>(.*?)\$\(IncludePath\)/m, 1]
#=> ".... omethingBinclude;...... omethingASource;"

或，mudasobwa建议你可以使用：

> string[/(?<=<IncludePath>).*?(?=\$\(IncludePath\))/m]
#=> ".... omethingBinclude;...... omethingASource;"
