Is String.replace any faster than String.split … String.join in ActionScript 3?

Is it any faster to use


myString.replace(/foo/g,"bar")

rather than


myString.split("foo").join("bar")

for long strings in ActionScript 3? Or are they just two comparable methods of achieving the same result?

What would be faster in this context String.Format or String.Replace?
Programming Languages

string str = 'my {0} long string {1} need formatting';

Should I be doing the following,


str = string.Format(str, "really", "doesn't");

or creating a method like so and calling str = str.ReplaceWithValues("really", "doesn't");


public string ReplaceWithValues(this string str, params object[] values) {
string ret = str;
for (int i = 0; i < values.Length; i++) {
ret = str.Replace(string.Concat("{", i, "}"), values.ToString());
}
return ret;
}

It seems like StringBuilder.AppendForm

String.replace() doesn't work after String.split()

I've got a problem with my js code:


var string = "sometext: tekst 555;";
var part = string.split(":");

So part[] is ["sometext", " tekst 555;"]


Now, I want to remove first white spaces in part[1], so I do:


part[1].replace(/s+(?=w)/, "");

and I should receive string "tekst 555;", but I get " tekst 555;". In fact, when I console.log this, it works! (In console in chrome and firefox) Can anybody tell me what is wrong with this code?

hey guys i have to read a huge xml file which consists of over 3 million records and over 10 million nested elements


naturally i am using xmltextreader and have got my parsing time down to about 40 seconds from earlier 90 seconds using multiple optimization tricks and tips


but i want to further save processing time as much as i can hence below question


quite a few elements are of type xs:boolean and the data provider always represents values as "true" or "false" - never "1" or "0"


for such cases my earliest code was:


if (xmlTextReader.Value == "true")
{
bool subtitled = t
