title: Modify HTML file and then get the modified html as an output
body: <p>I am new to jsoup so I am a little bit confused as to how to apply the modification to the original HTML file and then get it as an output.</p>
  
  <p>After giving changes by selecting the portion of html </p>
  
  <p>e.g. <code>Element elements = doc.select("_____").attr("_____",____);</code>
  (As this elements would only have the selected portion...)</p>
  
  <p>how can I apply this to the original doc? so that I can get the modified HTML as an output?</p>
  
  <p>Thank you very much</p>
