如何将以下RegExs组合为一个表达式？ [英] How can I combining the following RegExs into one expression?

问题描述

我正在使用以下RegEx从字符串中剥离HTML标记

I'm using the following RegEx to strip HTML tags from a string

<[^>]*>

但是，这并不能消除空白行。我找到了另一个RegEx，可以成功删除任何空白行：

This does not get rid of blank lines, however. I found this other RegEx that successfully removes any blank lines:

[#Chr(13)##Chr(10)#]+

我试图将两者合并：

ReReplaceNoCase(arguments.string, "(<[^>]*>)([#Chr(13)##Chr(10)#]+)", "", "ALL")

但这不起作用。我正在使用ColdFusion进行操作，这应该解释＃的迹象。

But this does not work. I'm using ColdFusion to do this, which should explain the # signs.

我认为（）用于在RegEx中对运算符进行分组，但在我尝试将两个表达式组合在一起时似乎不起作用。

I thought the () were used to group operators in RegEx, but it does not seem to work in my attempt to combine the two expressions.

推荐答案

假设您有两个正则表达式都可以使用，则可以使用交替方式将它们组合在一起：

Assuming that the two regular expressions you have work as you want then you can combine them using an alternation:

<[^>]*>|[#Chr(13)##Chr(10)#]+

我强烈怀疑您发布的正则表达式不实际上可以正常工作。我建议您不要使用正则表达式来解析HTML，因为HTML不是常规语言。请改用HTML解析器。

I strongly suspect though that the regular expressions you have posted don't in fact work correctly. I'd advise you not to use regular expressions to parse HTML as HTML is not a regular language. Use an HTML parser instead.
