如何从MRZ Passport代码字符串中提取信息？[等候接听]
提问于 2019-06-10 01:37:27
我想从MRZ护照代码中提取姓名，出生日期，护照号码和其他信息。我的MRZ代码如下：
"P<YEMALSHARAFI<<MARWAH<ABDULBARI<MAHYOUB<S<<08033227<1YEM9201017F2412311<<<<<<<<<<<<<<08"
首先，我想跳过前缀"P<YEM"然后存储名称变量"ALSHARAFI"，"MARWAH"，"ABDULBARI"，"MAHYOUB"，"S"以variable_1，variable_2的，variable_3的，variable_4，variable_5和跳过任何"<<"或"<"。之后将护照NO存储"08033227"到其变量中，然后存储国籍"YEM"，性别"F"，出生日期"92-01-01"和到期日期"24-12-31"。

该表达式将逐步捕获所有信息：
([A-Z]+)<(.+?)<<((.+?)<?)<([A-Z]+)<<([0-9]+)<([0-9]+)([A-Z]+)([0-9]{2})([0-9]{2})([0-9]{2})([0-9]+)([A-Z])([0-9]{2})([0-9]{2})([0-9]{2})([0-9]+)([<]+)([0-9]+)
我不确定某些数字，但它很容易被修改。

string pattern = @"([A-Z]+)<(.+?)<<((.+?)<?)<([A-Z]+)<<([0-9]+)<([0-9]+)([A-Z]+)([0-9]{2})([0-9]{2})([0-9]{2})([0-9]+)([A-Z])([0-9]{2})([0-9]{2})([0-9]{2})([0-9]+)([<]+)([0-9]+)";
string input = @"P<YEMALSHARAFI<<MARWAH<ABDULBARI<MAHYOUB<S<<08033227<1YEM9201017F2412311<<<<<<<<<<<<<<08
P<SMITH<<ALICE<BOB<GEORGE<KATE<OTHERS<S<<08033227<1YEM9201017F2412311<<<<<<<<<<<<<<08";
RegexOptions options = RegexOptions.Multiline;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
}

let m;
while ((m = regex.exec(str)) !== null) {
// This is necessary to avoid infinite loops with zero-width matches
if (m.index === regex.lastIndex) {
regex.lastIndex++;
}
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
