Regex:不开始一条线?
原标题:Regex: Not the beginning of a line?

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?

问题回答

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>(!^)只做罚款。

<编码> 页: 1

页: 1

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,]","");
