The trivial implementation is:
static public String escapeTags(String input) {
//Check if the string is null or zero length -- if so, return
//what was sent in.
if( input == null || input.length() == 0 ) {
return input;
}
//Use a StringBuffer in lieu of String concatenation -- it is
//much more efficient this way.
StringBuffer buf = new StringBuffer(input.length() + 6);
char ch = ' ';
int replacementCount = 0;
int len = input.length();
for(int i=0; i < len; i++) {
if (replacementCount > 4) {
//Abandon escaping
buf.setLength(0);
buf.append("<![CDATA[");
appendEscapingCDATA(buf, input);
buf.append("]]>");
return buf.toString();
}
ch = input.charAt(i);
if(ch == '<') {
buf.append("<");
replacementCount++;
} else if(ch == '>') {
buf.append(">");
replacementCount++;
} else {
buf.append(ch);
}
}
return buf.toString();
}
(lack of compiler == lack of syntax checking == lack of testing ;)
Shouldn't this method also escape ampersands (&) ? I know that it is called
escapeTags so it does what it says. Also the current escapeTags method
contains a mixture of tabs and spaces!
