我在android平台上工作，我使用一个字符串变量来填充html内容，之后我想删除一些单词（具体来说-删除之间的任何单词）<head>..</head>标签。有什么解决办法吗？
String newHtml = oldHtml.replaceFirst("(?s)(<head>)(.*?)(</head>)","$1$3");
解释：
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
