How can I combining the following RegExs into one expression?

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.

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.
