正则表达式语法错误代码:800A1399 [英] Regular expression syntax error code: 800A1399
问题描述
我正在学习正则表达式和 vbscript,以便通过每月添加用户输入的文本将文本附加到 .c 文件的新行.我在线收到一个正则表达式语法错误:68 char: 1 of the following VBScript,需要帮助整理:
I am learning regex and vbscript in order to append text to a .c file on a new line by adding user inputted text on a monthly basis. I receive a regular expression syntax error on line: 68 char: 1 of the following VBScript, and need help sorting it out:

第 68 行在哪里:
objFile = re.Replace(objFile, vbCrLf & lptmstr & vbCrLf)
正则表达式模式应该寻找 .c 代码并将用户输入附加到以换行符开头的换行符上,如下所示:
The regex pattern is supposed to seek .c code and append user inputs on a newline starting with a newline character as follows:
原始文件:
loss_pct_through_nov2015[a4] = 0.13155605112872;
loss_pct_through_nov2015[a5] = 0.23415898757080;
loss_pct_through_dec2015[a2] = 0.00283148378304;
loss_pct_through_dec2015[a3] = 0.39331380134641;
loss_pct_through_dec2015[a4] = 0.56333929692615;
loss_pct_through_dec2015[a5] = 0.04051541794440; <-append content from here
\n
}
更新文件:
loss_pct_through_nov2015[a4] = 0.13155605112872;
loss_pct_through_nov2015[a5] = 0.23415898757080;
loss_pct_through_dec2015[a2] = 0.00283148378304;
loss_pct_through_dec2015[a3] = 0.39331380134641;
loss_pct_through_dec2015[a4] = 0.56333929692615;
loss_pct_through_dec2015[a5] = 0.04051541794440;
\n <--new newline character replacing the old one to append content below
loss_pct_through_jan2016[a2] = 0.04051541794440;
loss_pct_through_jan2016[a4] = 0.04051541794440;
}
推荐答案
您有一个 积极的后视断言 ((?<=...)
) 在这个表达式的开头:
You have a positive lookbehind assertion ((?<=...)
) at the beginning of this expression:
re.Pattern = "(?<=loss_pct_through_([a-zA-Z]{3,5}\d{4})\[([a-zA-Z_]{1,2}\d{1,2})\]\s=\s\d\.\d{14}[;]\n)\n(?=\}\n)"
VBScript 正则表达式引擎不支持这些.
The VBScript regular expression engine doesn't support these.
