从doc文件提取asn部分

1.把doc文件复制到记事本里
2.python代码
asn_statu = 0
asn_txt_list = []
with open("D:/share/doc/38413.txt",encoding="gbk") as file:
    last_line = ""
    for line in file:
        if line.find('ASN1START') != -1:
            asn_txt_list.append("--" +last_line)
            asn_statu = 1

        if asn_statu:
        #    print(line)
            asn_txt_list.append(line)

        if line.find('ASN1STOP') != -1:
            asn_statu = 0
        if line.strip() != " ":
            last_line = line


with open("D:/share/doc/38413-f60.asn", "w") as file:
    for x in asn_txt_list:
        file.write(x)
