Html tag content wrapping

[seena mathew]

I am trying to wrap dynamic text based on number of characters(say for eg 5 characters in a line) in java.
So for example if the input Text is following, I need to do wrapping of text part only on
"Click me blh blah blah blah .... " and the other surrounding tags should be retained.

<b> <i><a href="http://www.google.com" target="_blank"> Click me blh blah blah blah .... </a> </i> </b>

I have tried writing code but have ended up getting so confused that I am not aware of what i am doing also


Code snippet

            char[] chars = inputString.toCharArray(); //<b> <i><a href="http://www.google.com" target="_blank"> Click blah blah blah .... </a> </i> </b>  
            List<String> lines = new ArrayList<String>();   //wrapped lines of pure text
            StringBuffer word = new StringBuffer(); //word whose length is compared
            StringBuffer htmlWord = new StringBuffer(); //html tag holder
            StringBuffer wrappedText = new StringBuffer(); //to hold the html tags  +reconstructed wrapped plain text

            for (int i = 0; i < chars.length; i++) {
	        StringBuffer st = new StringBuffer(inputString.toString());
	         if (chars[i] == '<') {
		do {
			htmlWord.append(chars[i]);
			i = i + 1;
		} while (chars[i] != '>');
		st.substring(htmlWord.length(), inputString.length());
		chars = st.toString().toCharArray();
	         else {
		while (chars[i] != '<') { //plain text
		      word.append(chars[i]); 
		      if ((word.length()) > len) {
			lines.add(word.toString()); //populate the arraylist
		 	word.delete(0, word.length()); //initialises the plain text buffer
		     }
		     i = i + 1;
		}
		st.substring(word.length(), inputString.length());
		chars = st.toString().toCharArray();
	           } //end of else tag
	            
                            //teconstructing the html tag +wrapped plain text 
                            wrappedText.append(htmlWord.toString());
	            for (int index = 0; index < lines.size(); index++) {
		int size = lines.size();
		wrappedString.append(lines.get(i));
		if (index < (size - 1)) {
		   // add a <br/> tag if the token is not the last token in the list
		   wrappedString.append("<br/>");
		}
	            }//end of for loop
		//reinitialise the bu	ffer
                             htmlWord.delete(0, htmlWord.length());
	             lines = new ArrayList<String>();

	            }
	}
	return wrappedString.toString();

Any suggestions would be of great help.

Something like:

String message = ...
if(the length of message is bigger than maxlength)
get the substring of message from 0 to maxlength
