String newHtml = oldHtml.replaceFirst("(?s)(<head>)(.*?)(</head>)","$1$3");
解釋：
oldHtml.replaceFirst(" // we want to match only one occurrance
(?s) // we need to turn Pattern.DOTALL mode on
// (. matches everything, including line breaks)
(<head>) // match the start tag and store it in group $1
(.*?) // put contents in group $2, .*? will match non-greedy,
// i.e. select the shortest possible match
(</head>) // match the end tag and store it in group $3
","$1$3"); // replace with contents of group $1 and $3

另一個解決方案:)
String s = "Start page <head> test </head>End Page";
StringBuilder builder = new StringBuilder(s);
builder.delete(s.indexOf("<head>") + 6, s.indexOf("</head>"));
System.out.println(builder.toString());

嘗試：
String input = "...<head>..</head>...";
String result = input.replaceAll("(?si)(.*<head>).*(</head>.*)","$1$2");
