Regex 返回字符串的所有匹配项

我试图找出如何从一个更大的字符串中获取字符串的每个匹配项

较大字符串的示例：

"xmp_id": 3243041, "certified": 1,"xmp_id": 3243042, "certified":
 1,"xmp_id": 3243043, "certified": 1,"xmp_id": 3243044, "certified":
 1,"xmp_id":     3243045, "certified": 1,"xmp_id": 3243046, "certified": 
1,"xmp_id": 3243047,     "certified": 1,"xmp_id": 3243048, "certified": 
1,"xmp_id": 3243049, "certified":     1,"xmp_id": 3243050, "certified":
 1,"xmp_id": 3243051, "certified": 1,"xmp_id":     3243052, "certified": 1,

在VB.Net中，我会使用类似这样的方法来获取每个“xmp_id”的值：

Dim inputString As String=RichTextBox1.Text
Dim模式为字符串=”（？Swift没有自己的正则表达式支持，但您可以使用Foundation的
NSRegularExpression
类。它生成
NSTextCheckingResult
对象。将Swift的
String
类型与
NSRegularExpression
和
NSTextCheckingResult
一起使用是一件痛苦的事，因此请先将您的将字符串放入
NSString

let text = "\"xmp_id\": 3243041, \"certified\": 1,\"xmp_id\": 3243042, \"certified\": 1,\"xmp_id\": 3243043, \"certified\": 1,\"xmp_id\": 3243044, \"certified\": 1,\"xmp_id\":     3243045, \"certified\": 1,\"xmp_id\": 3243046, \"certified\": 1,\"xmp_id\": 3243047,     \"certified\": 1,\"xmp_id\": 3243048, \"certified\": 1,\"xmp_id\": 3243049, \"certified\":     1,\"xmp_id\": 3243050, \"certified\": 1,\"xmp_id\": 3243051, \"certified\": 1,\"xmp_id\":     3243052, \"certified\": 1," as NSString

let rx = NSRegularExpression(pattern: "\"xmp_id\": ([0-9]+)", options: nil, error: nil)!
let range = NSMakeRange(0, text.length)
let matches = rx.matchesInString(text, options: nil, range: range)
for matchObject in matches {
    let match = matchObject as NSTextCheckingResult
    let range = match.rangeAtIndex(1)
    let value = text.substringWithRange(range)
    println(value)
}

我精简了这个
（？我如何循环这个来获取所有出现的情况？我还将检查这个，看看它是否至少找到了一个
let text = "\"xmp_id\": 3243041, \"certified\": 1,\"xmp_id\": 3243042, \"certified\": 1,\"xmp_id\": 3243043, \"certified\": 1,\"xmp_id\": 3243044, \"certified\": 1,\"xmp_id\":     3243045, \"certified\": 1,\"xmp_id\": 3243046, \"certified\": 1,\"xmp_id\": 3243047,     \"certified\": 1,\"xmp_id\": 3243048, \"certified\": 1,\"xmp_id\": 3243049, \"certified\":     1,\"xmp_id\": 3243050, \"certified\": 1,\"xmp_id\": 3243051, \"certified\": 1,\"xmp_id\":     3243052, \"certified\": 1," as NSString

let rx = NSRegularExpression(pattern: "\"xmp_id\": ([0-9]+)", options: nil, error: nil)!
let range = NSMakeRange(0, text.length)
let matches = rx.matchesInString(text, options: nil, range: range)
for matchObject in matches {
    let match = matchObject as NSTextCheckingResult
    let range = match.rangeAtIndex(1)
    let value = text.substringWithRange(range)
    println(value)
}
