Regex to replace namespace

Question

I have the following string

string s = "efile:ReturnState/efile:ReturnDataState/efile:processBO/composition/forms/IT204CP";

I would like to replace the efile: name space with an empty string and would like the result to be as follows

"ReturnState/ReturnDataState/processBO/composition/forms/IT204CP";

I also would like to know if there is a more generic way of doing this, as in something where I can replace any namespace like we see above and not just efile?

Just a guess but does your source XML (I'm assuming that is an xpath statement) specify a default namespace but you have a bunch of xpath that binds that namespace to efile? — dkackman

As DeanOC mentioned, there's no need to use a regex for this, but if you really want to, the regex is really straightforward

string result = Regex.Replace(s, "efile:", "");

You don't need Regex here; Regex is meant for pattern matching but you just need to replace a string literal with another one (empty string).

s = s.Replace(@"efile:","")

will remove all instances of efile:

if you want generic, then simply replace the "efile:" literal with a string variable and set the variable to whatever you want to remove.
