Escaping special characters in Java replace & > < \


i'm doing part in ETA system, which is a Webservice...
So it was needed to replcae some characters form XML data.

We have done this before sevaral time inside some methods...

But this time as the best practice i write a simple method to
do this...

hope it might useful to you:

Character Reference
&
&amp;
<
&lt;
>
&gt;
"
&quot;
'
&apos;



import java.text.CharacterIterator;
import java.text.StringCharacterIterator;



public class EscapeCharacter {
  
  public static void main(String[] args) {

        String str = "sdas\\d\\asa-&-adas-&-das-<-da->-sa";
        System.out.println(str);
      
        
        System.out.println(forXML(str));

    }

    public static String forXML(String aText) {
        aText = aText.replaceAll("&(?!amp;)", "&");
        final StringBuilder result = new StringBuilder();
        final StringCharacterIterator iterator =  new StringCharacterIterator(aText);
        char character = iterator.current();
        while (character != CharacterIterator.DONE) {
            if (character == '<') {
                result.append("<");
            } else if (character == '>') {
                result.append(">");
            } else if (character == '\"') {
                result.append(""");
            } else if (character == '\'') {
                result.append("'");
            } else {
                //the char is not a special one
                //add it to the result as is
                result.append(character);
            }
            character = iterator.next();
        }
        
        return result.toString();
    }


}

MDK Hospital opened in Horana

Image
Horana is getting a brand new private hospital! The M.D.K Healthcare Center & Hospital has just opened its doors on Anguruwathota Road, right next to the HNB bank branch. For years, many had to travel to Colombo for certain medical treatments, but hopes with new private hospital this will change. This new hospital, built by local businessman Mr. M.D. Piyananda Kularathna, comes with all the modern medical equipment we've been hoping for. It's wonderful to see such a major investment in Horana community's health. To makes this even better, I hope they have brought in highly skilled doctors and medical staff. No more long trips to Colombo for routine treatments! The hospital looks quite impressive too - modern and clean, just what you'd expect from a proper healthcare centre. The location is perfect as well. Being on Anguruwathota Road means it's easy to find and get to, whether you're coming from the town centre or surrounding areas. I've already notice...

Disable single quote Within Forms

This is a good method taught to me by my friend to disable any character in the keyboard Within Forms in your web page/ web application. A simple and effective method to disable specific characters (like single quotes) within form inputs on your webpage or web application. The Code <!DOCTYPE html> <html> <head> <script type="text/javascript"> function stopRKey(evt) { // Normalize the event object evt = evt || window.event; // For debugging - shows the keyCode console.log(evt.keyCode); // Block single quote (39 or 222 depending on browser) if (evt.keyCode == 39 || evt.keyCode == 222) { return false; } } // Attach the event handler to the document document.onkeypress = stopRKey; </script> </head> <body> <h3>Test Area</h3> <textarea rows="5"></text...

My Docker learning short notes

I had this note from long time in my Evernotes, I thought I should have post it here, so someone might find it useful. This is just Docker basics and commonly used commands that I've collected over time. Why Docker? Docker enables containerization - running applications in containers instead of virtual machines. Important notes: Containers are not VMs - they have different benefits Provides standardization across environments Enables continuous deployment from development to production Ensures consistency using the same container image throughout the deployment process Key Benefits: Self-contained environments Isolated from other applications Runs almost everywhere (especially in the Cloud) Small and lightweight Highly scalable Fast deployment Core Concepts Images An image is an executable package containing everything needed to run an application: ...
