How can I combining the following RegExs into one expression?

问题

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

<[^>]*>

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

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

I tried to combine both as such:

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

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

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.

回答1:

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

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

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.

回答2:

stripcr(ReReplaceNoCase(arguments.string, "(<[^>]*>)", "", "ALL"))
