Actually Alix Axel, above regex is wrong in latitude, longitude ranges point of view. 

Latitude measurements range from –90° to +90°
Longitude measurements range from –180° to +180°

So the regex given below validates more accurately. 
Also, as per my thought no one should restrict decimal point in latitude/longitude.

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

OR for Objective C

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

Now, what this does NOT do is restrict itself to this range:

<pre><code>(-90 to +90, and -180 to +180)
</code></pre>

Instead, it simple restricts itself to this range:

<pre><code>(-99 to +99, -199 to +199) 
</code></pre>

But the point is mainly just to break down each piece of the expression.

blocks|key|1166242|text|我相信您在应该使用\s+(空格)的地方使用了\w+(单词字符)。单词字符通常由A-Za-z0-9_组成，因此它排除了您的空格，从而进一步无法匹配可选的减号或数字。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1166243|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I believe you're using \w (word character) where you ought to be using \s (whitespace). Word characters typically consist of [A-Za-z0-9_], so that excludes your space, which then further fails to match on the optional minus sign or a digit.

Try this:

<pre><code>(?&lt;!\d)([-+]?(?:[1-8]?\d(?:\.\d+)?|90(?:\.0+)?)),\s*([-+]?(?:180(?:\.0+)?|(?:(?:1[0-7]\d)|(?:[1-9]?\d))(?:\.\d+)?))(?!\d)`
</code></pre>

I'm trying to create a regular expression for matching latitude/longitude coordinates. For matching a double-precision number I've used <code>(\-?\d+(\.\d+)?)</code>, and tried to combine that into a single expression:

<pre><code>^(\-?\d+(\.\d+)?),\w*(\-?\d+(\.\d+)?)$
</code></pre>

I expected this to match a double, a comma, perhaps some space, and another double, but it doesn't seem to work. Specifically it only works if there's NO space, not one or more. What have I done wrong?

Regular expression for matching latitude/longitude coordinates?

我正在尝试创建一个正则表达式来匹配纬度/经度坐标。为了匹配双精度数字，我使用了(\-?\d+(\.\d+)?)，并尝试将其组合到一个表达式中：^(\-?\d+(\.\d+)?),\w*(\-?\d+(\.\d+)?)$我期望这个匹配一个双精度，一个逗号，也许一些空格，和另一个双精度，但它似乎不起作用。具体地说，只有当没有空间，而不是一个或多个空间时，它才起作用。我做错了什么？
