用于匹配纬度/经度坐标的正则表达式?

空白是\s,不是\w

^(-?\d+(\.\d+)?),\s*(-?\d+(\.\d+)?)$

^[-+]?([1-8]?\d(\.\d+)?|90(\.0+)?),\s*[-+]?(180(\.0+)?|((1[0-7]\d)|([1-9]?\d))(\.\d+)?)$

比赛

• +90.0, -127.554334
• 45, 180
• -90.000, -180.0000
• 47.1231231, 179.99999999

• -90., -180.
• +90.1, -100.111
• -91, 123.456
• 045, 180

我使用的是这些数字(十进制格式,有6个十进制数字):

^(\+|-)?(?:90(?:(?:\.0{1,6})?)|(?:[0-9]|[1-8][0-9])(?:(?:\.[0-9]{1,6})?))$

经度

^(\+|-)?(?:180(?:(?:\.0{1,6})?)|(?:[0-9]|[1-9][0-9]|1[0-7][0-9])(?:(?:\.[0-9]{1,6})?))$

经度测量范围从180°到+180°

而且,按照我的想法,没有人应该限制纬度/经度的小数点。

^([-+]?\d{1,2}([.]\d+)?),\s*([-+]?\d{1,3}([.]\d+)?)$

或目标C

^([-+]?\\d{1,2}([.]\\d+)?),\\s*([-+]?\\d{1,3}([.]\\d+)?)$

^-?[0-9]{1,3}(?:\.[0-9]{1,10})?$

正则表达式细分:

^-?[0-9]{1,3}(?:\.[0-9]{1,10})?$

-? #接受负值

^

[0-9]{1,3} #匹配1-3个数字(即0-999)

(?: #尝试匹配。。。

\. #小数点

[0-9]{1,10}

)? #…可选

$ #字符串结尾

^(\()([-+]?)([\d]{1,2})(((\.)(\d+)(,)))(\s*)(([-+]?)([\d]{1,3})((\.)(\d+))?(\)))$

请访问:

http://regexpal.com/

将表达式粘贴到顶部框中,然后将以下内容放入底部框中:

(80.0123, -34.034)
(80.0123)
(80.a)
(980.13, 40)
(99.000, 122.000)

正则表达式细分:

^                    # The string must start this way (there can't be anything before). 
    (\()             # An opening parentheses (escaped with a backslash).
    ([-+]?)          # An optional minus, or an optional plus.
    ([\d]{1,2})      # 1 or 2 digits (0-9).
    (                # Start of a sub-pattern.
        (            # Start of a sub-pattern.
            (\.)     # A dot (escaped with a backslash).
            (\d+)    # One or more digits (0-9).
            (,)      # A comma.
        )            # End of a sub-pattern.
    )                # End of a sub-pattern.
    (\s*)            # Zero or more spaces.
    (                # Start of a sub-pattern.
        ([-+]?)      # An optional minus, or an optional plus. 
        ([\d]{1,3})  # 1 to 3 digits (0-9).
        (            # Start of a pattern.
            (\.)     # A dot (escaped with a backslash).
            (\d+)    # One or more digits (0-9).
        )?           # End of an optional pattern.
        (\))         # A closing parenthesis (escaped with a backkslash).
    )                # End of a pattern
$                    # The string must end this way (there can't be anything after).

现在,它没有做的是将自己限制在这个范围内:

(-90 to +90, and -180 to +180)

相反,它仅限于此范围:

(-99 to +99, -199 to +199) 

但重点主要是分解每一个表达。

这里有一个更严格的版本:

^([-+]?\d{1,2}[.]\d+),\s*([-+]?\d{1,3}[.]\d+)$

• 纬度= -90 -- +90
• 经度= -180 -- +180

@macro-ferrari 我确实找到了一个缩短它的方法,而且根据最近所有关于 regex engines

const LAT_RE = /^[+-]?(([1-8]?[0-9])(\.[0-9]{1,6})?|90(\.0{1,6})?)$/;

const LONG_RE = /^[+-]?((([1-9]?[0-9]|1[0-7][0-9])(\.[0-9]{1,6})?)|180(\.0{1,6})?)$/;

纬度: result = re.match("^[+-]?((90\.?0*$)|(([0-8]?[0-9])\.?[0-9]*$))", '-90.00001')

result = re.match("^[+-]?((180\.?0*$)|(((1[0-7][0-9])|([0-9]{0,2}))\.?[0-9]*$))", '-0.0000')

在这个例子中,纬度应该失败。

我相信您使用的是\w(单词字符),而您应该使用\s(空格)。单词字符通常由[A-Za-z0-9_304;]组成,这样就排除了空格,而空格在可选的减号或数字上进一步无法匹配。

这适用于这样的格式:3137.4'E

^[-]?\d{1,2}[ ]*ͦ[ ]*\d{1,2}\.?\d{1,2}[ ]*\x27[ ]*\w$

红宝石

经度

/^(-?(?:1[0-7]|[1-9])?\d(?:\.\d{1,8})?|180(?:\.0{1,8})?)$/ === longitude.to_s

纬度

/^(-?[1-8]?\d(?:\.\d{1,8})?|90(?:\.0{1,8})?)$/ === latitude.to_s

在目标C中,检查经纬度的正确模式的一个完整而简单的方法是:

 -( BOOL )textIsValidValue:(NSString*) searchedString
{
    NSRange   searchedRange = NSMakeRange(0, [searchedString length]);
    NSError  *error = nil;
    NSString *pattern = @"^[-+]?([1-8]?\\d(\\.\\d+)?|90(\\.0+)?),\\s*[-+]?(180(\\.0+)?|((1[0-7]\\d)|([1-9]?\\d))(\\.\\d+)?)$";
    NSRegularExpression* regex = [NSRegularExpression regularExpressionWithPattern: pattern options:0 error:&error];
    NSTextCheckingResult *match = [regex firstMatchInString:searchedString options:0 range: searchedRange];
    return match ? YES : NO;
}

哪里 搜索字符串 是用户将在相应文本字段中输入的输入。

$latitude $longitude

$latitude_pattern  = '/\A[+-]?(?:90(?:\.0{1,18})?|\d(?(?<=9)|\d?)\.\d{1,18})\z/x';
$longitude_pattern = '/\A[+-]?(?:180(?:\.0{1,18})?|(?:1[0-7]\d|\d{1,2})\.\d{1,18})\z/x';
if (preg_match($latitude_pattern, $latitude) && preg_match($longitude_pattern, $longitude)) {
  // Valid coordinates.
}

(?<latitude>-?\d+\.\d{3,10}),(?<longitude>-?\d+\.\d{3,10})

你可以试试这个:

var latExp = /^(?=.)-?((8[0-5]?)|([0-7]?[0-9]))?(?:\.[0-9]{1,20})?$/;
var lngExp = /^(?=.)-?((0?[8-9][0-9])|180|([0-1]?[0-7]?[0-9]))?(?:\.[0-9]{1,20})?$/;

^[-+]?(([0-8]\\d|\\d)(\\.\\d+)?|90(\\.0+)?)$,\s*^[-+]?((1[0-7]\\d(\\.\\d+)?)|(180(\\.0+)?)|(\\d\\d(\\.\\d+)?)|(\\d(\\.\\d+)?))$

试试这个:

(?<!\d)([-+]?(?:[1-8]?\d(?:\.\d+)?|90(?:\.0+)?)),\s*([-+]?(?:180(?:\.0+)?|(?:(?:1[0-7]\d)|(?:[1-9]?\d))(?:\.\d+)?))(?!\d)`
