如何使用正则表达式去除字符串中多余的空格 [英] How to Remove Excess Whitespace in String Using Regex

问题描述

我想使用正则表达式解析一系列段落，但不幸的是，该段落在句子之间出现了许多空格，有时还有单词.我希望能够删除所有多余的空白，但我不确定如何......有人有任何想法吗?我不想删除所有空格，这是我迄今为止发现的唯一内容，但要保持常规段落格式，例如在每个单词之后都有一个空格，并且每个标点+单词之后都有一个空格.我正在用 Perl 编码.

I have a series of paragraphs that I want to parse using regular expressions, but unfortunately, the paragraph is appearing with many white spaces in between sentences, and sometimes words. I would like to be able to remove all excess white space, but I'm unsure how... Anyone have any ideas? I don't want to remove all whitespace, which is the only thing I've found so far, but to keep regular paragraph format, as in after every word have a white space, and after every punctuation+word have a whitespace. I am coding in Perl.

任何帮助将不胜感激！
