PHP preg_match圣经经文格式

Question

我正在努力构建一个正则表达式来解析这种字符串(圣经经文):

  'John 14:16–17, 25–26'
  'John 14:16–17'
  'John 14:16'
  'John 14'
  'John'

所以基本模式是:

Book [[Chapter][:Verse]]

章和节是可选的.

Answer 1

我认为这可以满足您的需求:

\w+\s?(\d{1,2})?(:\d{1,2})?([-–]\d{1,2})?(,\s\d{1,2}[-–]\d{1,2})?

假设:

• 数字始终为1位或2位数
• 短划线将匹配以下任一项-和–

以下是带注释的正则表达式:

"
\w         # Match a single character that is a “word character” (letters, digits, and underscores)
   +          # Between one and unlimited times, as many times as possible, giving back as needed (greedy)
\s         # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   ?          # Between zero and one times, as many times as possible, giving back as needed (greedy)
(          # Match the regular expression below and capture its match into backreference number 1
   \d         # Match a single digit 0..9
      {1,2}      # Between one and 2 times, as many times as possible, giving back as needed (greedy)
)?         # Between zero and one times, as many times as possible, giving back as needed (greedy)
(          # Match the regular expression below and capture its match into backreference number 2
   :          # Match the character “:” literally
   \d         # Match a single digit 0..9
      {1,2}      # Between one and 2 times, as many times as possible, giving back as needed (greedy)
)?         # Between zero and one times, as many times as possible, giving back as needed (greedy)
(          # Match the regular expression below and capture its match into backreference number 3
   [-–]       # Match a single character present in the list “-–”
   \d         # Match a single digit 0..9
      {1,2}      # Between one and 2 times, as many times as possible, giving back as needed (greedy)
)?         # Between zero and one times, as many times as possible, giving back as needed (greedy)
(          # Match the regular expression below and capture its match into backreference number 4
   ,          # Match the character “,” literally
   \s         # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   \d         # Match a single digit 0..9
      {1,2}      # Between one and 2 times, as many times as possible, giving back as needed (greedy)
   [-–]       # Match a single character present in the list “-–”
   \d         # Match a single digit 0..9
      {1,2}      # Between one and 2 times, as many times as possible, giving back as needed (greedy)
)?         # Between zero and one times, as many times as possible, giving back as needed (greedy)
"

以下是它在php中使用的一些示例:

if (preg_match('/\w+\s?(\d{1,2})?(:\d{1,2})?([-–]\d{1,2})?(,\s\d{1,2}[-–]\d{1,2})?/', $subject)) {
    # Successful match
} else {
    # Match attempt failed
}

获取给定字符串中所有匹配项的数组

preg_match_all('/\w+\s?(\d{1,2})?(:\d{1,2})?([-–]\d{1,2})?(,\s\d{1,2}[-–]\d{1,2})?/', $subject, $result, PREG_PATTERN_ORDER);
$result = $result[0];

Answer 2

在这里试试这个

\n\n

\\b[a-zA-Z]+(?:\\s+\\d+)?(?::\\d+(?:\xe2\x80\x93\\d+)?(?:,\\s*\\d+(?:\xe2\x80\x93\\d+)?)*)?\n

\n\n

在 Regexr 上查看并测试它

\n\n

因为(?:,\\s*\\d+(?:\xe2\x80\x93\\d+)?)*最后你可以有一个诗句列表，最后的诗句范围。
