Basically I would like to decode a given Html document, and replace all special chars, such as \" \" -> \" \", \">\" -

Answer 1

Incase you want to mimic what php function htmlspecialchars_decode does use php function get_html_translation_table() to dump the table and then use the java code like,

static Map html_specialchars_table = new Hashtable();
static {
        html_specialchars_table.put("<","<");
        html_specialchars_table.put(">",">");
        html_specialchars_table.put("&","&");
}
static String htmlspecialchars_decode_ENT_NOQUOTES(String s){
        Enumeration en = html_specialchars_table.keys();
        while(en.hasMoreElements()){
                String key = en.nextElement();
                String val = html_specialchars_table.get(key);
                s = s.replaceAll(key, val);
        }
        return s;
}
