我正试图删除“……”在文本中,并将其替换为“.”.
我的代码: System.out.println(TextHandler.class.toString() + " removeExcessiveSpaces E2 " + text); while (text.contains(". .")) { text = text.replaceAll(". .","."); } System.out.println(TextHandler.class.toString() + " removeExcessiveSpaces E3 " + text); 文字输入: "from the streets' fit but you know it. . this is just another case of female stopping play,. in an otherwise total result of a holiday. by m-uhjuly 04,2006. . 8 . 42 . .. .... . . . . . . . . <script>//<![cdata[" 预期产量: "from the streets' fit but you know it this is just another case of female stopping play,2006. . 8 . 42 .. <script>//<![cdata[" 观察到的输出: from the streets' fit but you know it. . this is just another case of female stopping play,2006. . 8 . 42 . .. .... . . . . . . . . <script>//<![cdata[ (与输入无差异) 为什么不工作? 解决方法
String#contains不期望正则表达式只是普通字符串.
所以使用: if (text.contains(". .")) { text = text.replaceAll(". .","."); } 或者只是使用String#replace: text = text.replace(". .","."); (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
