Php 正则表达式：从字符串中分离nn:nn,php,regex,Php,Regex,我已经做了几个小时了，这里的解决方案都没有真正帮助我。我有一个文本文件格式为“NN:NN字符串在这里”。实际文件如下所示。我需要将章节：诗句从实际的弦乐诗句中正则化。正如您所看到的，并不是所有的都用换行符分隔。我得到的最接近的是（\d{1,2}:\d{1,2}）[^\d]*，但它实际上只分隔了NN:NN 我怎样才能完成分离字符串 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham

我已经做了几个小时了，这里的解决方案都没有真正帮助我。我有一个文本文件格式为“NN:NN字符串在这里”。实际文件如下所示。我需要将章节：诗句从实际的弦乐诗句中正则化。正如您所看到的，并不是所有的都用换行符分隔。我得到的最接近的是

（\d{1,2}:\d{1,2}）[^\d]*

我怎样才能完成分离字符串

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.

具体要求是什么？这些NN:NNs后面是否应该有空格和大写字母？您只是在提取它们还是要插入一些内容？看，我正在提取它们。在NN:NN向我们展示最终结果之后应该没有空格。
