Replacing tag with letters using JSoup

Hello I have tried these answers: How to replace a tag using jsoup and Replace HTML tags using jsoup to my case unsuccessfully. I am parsing a website with JSoup and I ran accross letter-look GIF images. Fortunately those gif images have a specific name, e.g. a.gif for letter "A".

HTML input:

<body>
  <p><img src="http://www.example.com/images/a.gif" align="left">mong us!</p>
</body>

Desired output:

<body>
  <p>Among us!</p>
</body>

My java code (below) does not print the expected output:

Document document = Jsoup.connect("http://www.example.com").get();
if(document.select("img").attr("src").contains("a.gif"))
  {
    document.select("img").get(0).replaceWith(new Element(Tag.valueOf("img"), "A"));
  }

Thank you for your help.

try this:

Document document = Jsoup.parse(html);
if (document.select("img").get(0).attr("src").contains("a.gif")) {
    document.select("img").get(0).replaceWith(new TextNode("A", null));
}

Using TextNode instead of Element.

Document document = Jsoup.parse(html);
if (document.select("img").get(0).attr("src").contains("a.gif")) {
    document.select("img").get(0).replaceWith(new TextNode("A", ""));
    System.out.println(document);
}

The above code can print html as you expected.

      {
       String result ="";
       String src =document.select("img").attr("src").text();
       result = src.replace(src,"A");
       System.out.println(result);
