How to modify the specific value in the html through jsoup

Here is my code:

Elements parents = doc.select("input[value]");
for (Element parent : parents) {
    System.out.println(
        parent.attr("value")
            .replace("X70xAkOaaAeWGxNgWnTJolmy6/FFoFaBD47IzyBYWf4=", "Ranjan")
            .replace("17572418", "17572418123")
            .replace("200", "199")
            .replace("2018-09-13T16:28:28Z", "2018-09--5T16:28:28Z")
            .replace("2018-09-17", "2018-09-25")
    );
}

But when I print System.out.println(doc); it is printing the same old value instead I should get the modified one. How to modify the specific value which are under input tag?

EDIT:

I have the following HTML: 

<input type="hidden" name="sessionValidity" value="2018-09-13T16:28:28Z">
<input type="hidden" name="shipBeforeDate" value="2018-09-17"> 
<input type="hidden" name="merchantReturnData" value=""> 
<input type="hidden" name="shopperLocale" value="en_GB"> 
<input type="hidden" name="skinCode" value="Ce0xkMuQ"> 
<input type="hidden" name="merchantSig" value="X70xAkOaaAeWGxNgWnTJolmy6/FFoFaBD47IzyBYWf4=">

I am not familiar with Jsoup but it seems like you do not change the value of the attributes. Element.attr(String s) returns a String. I guess you meant to use public Element attr​(String attributeKey, String attributeValue).

Then you use public String replace(CharSequence target, CharSequence replacement) which does not modify the String itself (String is immutable, replace returns a new String)

I think you want to do this way instead:

private static String html = 
    "<input type=\"hidden\" name=\"sessionValidity\" value=\"2018-09-13T16:28:28Z\">\n" +
    "<input type=\"hidden\" name=\"shipBeforeDate\" value=\"2018-09-17\"> \n" +
    "<input type=\"hidden\" name=\"merchantReturnData\" value=\"\"> \n" +
    "<input type=\"hidden\" name=\"shopperLocale\" value=\"en_GB\"> \n" +
    "<input type=\"hidden\" name=\"skinCode\" value=\"Ce0xkMuQ\"> \n" +
    "<input type=\"hidden\" name=\"merchantSig\" value=\"X70xAkOaaAeWGxNgWnTJolmy6/FFoFaBD47IzyBYWf4=\">";

public static void main(String[] args) {
    Document doc = Jsoup.parse(html);
    doc.select("input[name$=merchantSig]").attr("value", "Ranjan");
    // and the other ones
    System.out.println(doc.html());

}

that prints out 

<html>
    <head></head>
    <body>
        <input type="hidden" name="sessionValidity" value="2018-09-13T16:28:28Z">
        <input type="hidden" name="shipBeforeDate" value="2018-09-17">
        <input type="hidden" name="merchantReturnData" value="">
        <input type="hidden" name="shopperLocale" value="en_GB">
        <input type="hidden" name="skinCode" value="Ce0xkMuQ">
        <input type="hidden" name="merchantSig" value="Ranjan">
    </body>
</html>

You can see that the merchantSig value has been modified
