Question

有一个包含内容的文件：

OR

我想在标题具有诸如abc_4abk_keys44a之类的键的所有模块中从B.dim中提取2.642，为此，我首先需要搜索键，然后在该模块中，从START'keyword'到END'keyword'，然后提取2.642作为浮点型变量。我不知道要使用的正则表达式，有人可以帮助我吗？

ON abc_4abk_keys44a
keyword : c
START c
hashtags;
START
student_4e;
END
professor_u6;
topper_98j;
A.dim 3.246 burst R1;
B.dim 2.642 burst R6;
K.dimension 3.564 burst L4;
END c
ON amc_4sn_bname1
keyword : k4
START k4
hashtags;
START
student_4e;
END
professor_u6;
topper_98j;
A.dim 3.246 burst R1;
B.dim 2.642 burst R6;
K.dimension 3.564 burst L4;
END k4

Answer 1

使用char d[42]而不是使用正则表达式在空格处分割每一行。

遍历所有行，并设置一个变量，该变量指示您是否处于与Response.Clear(); Response.AppendHeader("username", "Username"); Response.AppendHeader("password", "abc"); Response.Status = "301 Moved permanently"; Response.AppendHeader("Location", "https://test.local.com"); Response.End();匹配的单位中。
