我有这样的说明:<代码>------ 页: 1
现在我想删除所有<代码>-的术语,但第一个<代码>-、<代码>、和编号除外。 其结果应为243,33。 我如何这样做?

你的问题仍然很明确,但是这产生了你想要的产出:
----------- 243f,33f---- .replace(/(?!^-)[^d,]+/g, )
The regex matches one or more of any character except digits or commas, after making sure the first character isn t a hyphen at the beginning of the string.
http://www.un.org。 对于那些使用<代码>(?<!^)的reg人,然后撤回,因为Javagust不支持 look,这是必要的。 我知道这些答复还有其他问题,但为了将“不是开始铺设”与“条码”相匹配,<条码>(!^)条码>只做罚款。

1. 替代从第二个特性的类别
string.charAt(0) + string.substring(1).replace("-","");
但是,我不知道yn是否正确。
EDIT:
oh 如果你想去掉你可以去除任何非数字和非共同点:
string.charAt(0) + string.substring(1).replace("[^0-9,]","");
引证:
(?:(^-)|[^d,
])
替换
$1
See it here on Regexr
越是困难,因为 Java字不支持 look。 因此,如果在线路开始时有<代码>-,则该编码将自行替换,而其他对应编号$1
则空置,未作任何改动。
