I wish this helpful for you The best way to accomplish this is to NOT use regular expression and use a proper HTML parser. HTML is not a regular language and doing this with regular expression will be tedious, hard to maintain, and more than likely still contain various errors.
HTML parsers, on the hand, are well-suited for the job. Many of them are mature and reliable, and they take care of every little details for you and makes your life much easier.

Does that help Use jsoup to extract content from html tags. Then you can use regex on the string extracted.
Download jsoup from
code :
    String url = "<div id=\"foo\"><div class=\"bar\">xyz</div><div id=\"alert\"><strong>Foo Bar 2% foobar.</strong></div></div>";
    Document doc = Jsoup.parse(url);  
    Elements elements = doc.select("strong");
    String s= elements.text();
    Pattern p = Pattern.compile("[0-9]{1,3}");
    Matcher m = p.matcher(s); 
    while (m.find()) {
       String result =m.group();

this one helps. UPDATED , is this what you are looking for? not sure...
code :
public class Temp {

    public static void main (String args[]) {
        String input = convertSting("2BXX09XX2BYYYY");
        input = replaceSize(input, "0A");


    private static String replaceSize(String input, String newSizeVal) {
        int sizePosition = 4;
        return input.substring(0, sizePosition) + newSizeVal + input.substring(sizePosition + newSizeVal.length(), input.length());

    public static String convertSting (String input) {
        String findString = "2B";

        int firstIndex = input.indexOf(findString) + findString.length();
        return input.substring(0, firstIndex) + input.substring(firstIndex, input.length()).replace(findString, "2B2B");

help you fix your problem Possibly not the most efficient, but should do the job:
str.replace(/<([^>]+)>/g, function(m){ return m.replace(/ /gi, ' '); });

RegEx: Matching text that is not inside and part of a HTML tag

I hope this helps . Regexes are a clunky and unreliable way to work on markup. I would suggest using a DOM parser such as SimpleHtmlDom:

will be helpful for those in need Solution in just one step, with negative lookahead:
preg_replace("#\b(sapien)\b(?![^<>]*(<\/a|<\/div|>))#i", "\\1", $input);
