No, that should be two replacements: The *? operator is non-greedy, so
\\S*? matches the shortest possible sequence of non-space characters.


package at.hjp.regexptest;

public class RegExpTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		String s = "Hi&quot;I'm-a&quot;-dash-seperated-&quot;string.&quot;";
		String s1 = s.replaceAll("&quot;(\\S*?)&quot;", "<span class=\"quoted\">$1</span>");
		System.out.println(s1);

	}

}

prints:

Hi<span class="quoted">I'm-a</span>-dash-seperated-<span class="quoted">string.</span>
