Make a flavor of QString::split() which splits by a collection of chars

#include <QTime>
int main(int argc, char *argv[])
{
	QString s1 = "This is a long sentence\twith several\t spaces and tabs and some new\nlines\r\nas separators which needs to be split\n";
	QString s2 = "This is a long sentence with several spaces and tabs and some new lines as separators which needs to be split";

	QTime timer;
	timer.start();
	QRegExp reg("\\s+");
	for(int i = 0; i < 10000; ++i)
	{
		QStringList sl = s1.split(reg, QString::SkipEmptyParts);
	}
	printf("QRegExp took: %d sec\n", timer.elapsed());

	timer.start();
	for(int i = 0; i < 10000; ++i)
	{
		QStringList sl = s2.split(' ', QString::SkipEmptyParts);
	}
	printf("space took: %d sec\n", timer.elapsed());
	return 0;
}
