正则表达式:将 nn:nn 与字符串分开



我已经在这里工作了几个小时,这里没有一个解决方案真正帮助了我。我有一个格式为"NN:NN 字符串转到此处"的文本文件。实际文件如下。我需要从实际的字符串诗句中正则表达式章节:诗句。如您所见,并非所有都用换行符分隔。我得到的最接近的是(d{1,2}:d{1,2})[^d]*但它只是真正分开了 NN:NN。

如何完成字符串分离?

1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham.
1:2 Abraham begat Isaac; and Isaac begat Jacob; and Jacob begat Judas and his brethren; 1:3 And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram; 1:4 And Aram begat Aminadab; and Aminadab begat Naasson; and Naasson begat Salmon; 1:5 And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; 1:6 And Jesse begat David the king; and David the king begat Solomon of her that had been the wife of Urias; 1:7 And Solomon begat Roboam; and Roboam begat Abia; and Abia begat Asa; 1:8 And Asa begat Josaphat; and Josaphat begat Joram; and Joram begat Ozias; 1:9 And Ozias begat Joatham; and Joatham begat Achaz; and Achaz begat Ezekias; 1:10 And Ezekias begat Manasses; and Manasses begat Amon; and Amon begat Josias; 1:11
And Josias begat Jechonias and his brethren, about the time they were carried away to Babylon: 1:12 And after they were brought to Babylon, Jechonias begat Salathiel; and Salathiel begat Zorobabel; 1:13 And Zorobabel begat Abiud; and Abiud begat Eliakim; and Eliakim begat Azor; 1:14 And Azor begat Sadoc; and Sadoc begat Achim; and Achim begat Eliud; 1:15 And Eliud begat Eleazar; and Eleazar begat Matthan; and Matthan begat Jacob; 1:16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.
1:17 So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations.
1:18 Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.

你很接近。以下方法应该有效:

preg_match_all("/(d{1,2}:d{1,2})([^d]*)/", $str, $output_array);
print_r(array_combine($output_array[1], $output_array[2]));

正则表达式(d+:d+)R?s*(.+?(?=s*d+:d+|$))

详情

  • d匹配一个数字(等于 [0-9](
  • R 匹配任何 Unicode 换行符序列
  • s 匹配任何空格字符
  • .+?匹配任何字符(行终止符除外(
  • $ 断言字符串末尾的位置
  • ? 0 次到一次之间的匹配

preg_match_all("/(d+:d+)R?s*(.+?(?=s*d+:d+|$))/m", $text, $matches);
print_r(array_combine($matches[1], $matches[2]));

输出

这不仅相当快,而且还会从文本值中修剪所有前导/尾随空格。 *所有文本行都以 :;. 结尾 我正在利用这一事实来提高模式效率。

如果在实际项目中,某些句子包含换行符(您的示例不包含(,则在第二个模式分隔符之后添加s以使.也匹配换行符。

~(d{1,2}:d{1,2})s+(.*?[:;.](?=s*(?:d{1,2}:d{1,2})|$))~ 2193步
