1. Remove Particular Html tag from String.

Requirement - Remove <font> tags, even if it has multiple then remove all.

Eg: <font face='Helvetica Neue, Helvetica, Arial, sans-serif' size='2'>ClaimCode = 'CLAppImp_8c227045811'</font> and ABCCC='543545'<font face='Helvetica Neue, Helvetica, Arial, sans-serif' size='2'>ClaimCode3333 = 'CLAppImp_8c2270458112222'</font>

Solution: Used Recurrsive method - removeHTMLTag

public class RemoveFontTag {

        private String finalRemovedString;

    public static void main(String[] args) {

        //String script = "ClaimCode = 'CLAppImp_8c227045811'";

        String script = "<font face='Helvetica Neue, Helvetica, Arial, sans-serif' size='2'>ClaimCode = 'CLAppImp_8c227045811'</font> and ABCCC='543545'<font face='Helvetica Neue, Helvetica, Arial, sans-serif' size='2'>ClaimCode3333 = 'CLAppImp_8c2270458112222'</font>";

        String htmlTag = "font";

        RemoveFontTag removeFontTag = new RemoveFontTag();

        boolean done = removeFontTag.removeHTMLTag(script,htmlTag);

        System.out.println("final returned String finalString ===> "+removeFontTag.finalRemovedString);

    }

    

    

    public boolean removeHTMLTag(String script,String htmlTag){

        String finalString = script;

        try {

            System.out.println("###########################removeHTMLTag1 ###################### : "+script);

            System.out.println("htmlTag : "+htmlTag);

            

            //script.replaceAll("\\<.*?>","");

            if(script != null && htmlTag != null && script.contains("<"+htmlTag)){

            

                String firstString = finalString.substring(0, finalString.indexOf("<"+htmlTag));

                System.out.println("firstString : "+firstString);

                String secondString = finalString.substring(finalString.indexOf("<"+htmlTag), finalString.length());

                System.out.println("secondString : "+secondString);

                String removedString = secondString.substring(secondString.indexOf(">")+1,secondString.length());

                finalString = firstString + removedString;

                System.out.println("removedString : "+removedString);

                finalString = finalString.replace("</"+htmlTag+">", "");

                System.out.println("finalString : "+finalString);

                this.finalRemovedString = finalString;

                removeHTMLTag(finalString,htmlTag);

                return true;

            }

            else{

                this.finalRemovedString = finalString;

                return true;

            }

        } catch (Exception e) {

            System.out.println("Exception : "+e.getMessage());

            this.finalRemovedString = finalString;

            return false;

        }

        

    }
