使用Java模式和匹配器将XML单词插入MySQL

Question

I want to keep track of word usage in a group chat using MySQL database. Currently messages passed into the insertWords method is an XML string. The XML string can have special characters such as ' and " . Is there a better way than using String.replace to convert XML formatted strings to normal messages?

If my message is: I'm bad, but they aren't that "good"

How can I convert it to: I'm bad, but they aren't that "good"

My code will insert apos 2 times and quot 2 times. How do I fix this?

Pattern p = Pattern.compile("[\\w']+");

PreparedStatement insertWordStmt = connection.prepareStatement("INSERT INTO word (word, count) VALUES (?, 1) " +
        "ON DUPLICATE KEY UPDATE count=count+1");

public void insertWords(String msg) {
    msg = msg.toLowerCase();
    try {
        Matcher m = p.matcher(msg);
        while ( m.find() ) {
            String word = msg.substring(m.start(), m.end());
            insertWordStmt.setString(1, word);
            insertWordStmt.executeUpdate();
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
}

Answer 1

to add double quote matching, try

Pattern p = Pattern.compile("[\\w'\"]+"); 

EDIT after comments

msg = msg.toLowerCase().replace("'","'").replace("&quote;","\"");
