推荐答案

因为你不想要逗号，我想最好匹配单词而不是而不是分隔空格。

我会使用RegEx，如：\ w +



只是一些有趣的链接来帮助构建和调试RegEx 。

以下是RegEx文档的链接：

perlre - perldoc.perl .org [ ^ ]

以下是帮助构建RegEx并调试它们的工具的链接：

.NET Regex Tester - Regex Storm [ ^ ]

Expresso正则表达式工具 [ ^ ]

RegExr：Learn，Build，&测试RegEx [ ^ ]

在线正则表达式测试器和调试器：PHP，PCRE，Python，Golang和JavaScript [ ^ ]

这个显示RegEx是一个很好的图表，它非常有助于理解RegEx的作用：

Debuggex：在线可视正则表达式测试器。 JavaScript，Python和PCRE。 [ ^ ]

这个网站也在一个漂亮的图表中显示正则表达式，但无法测试与RegEx匹配的内容：

Regexper [ ^ ]

Since you don't want commas, I guess it is preferable to match words rather than split on spaces.
I would use a RegEx like: \w+

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:
Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx:
Regexper[^]
