java - Read html file and replace string in jsp -

How to add some text in the div with id = "sw" and befor "? Adding and writing in response to JSP?

"index_012. Html is content:

   gt;> head> gt; & lt; body & gt; 
 
 
 & lt; / section & gt; & lt; div class = "clear"> 
  / div> & lt; / body & gt;  

My jsp code is:

  FileReader fr = new FileReader (stringbilder result = "" string baller result = "" ; St String line = zero; // find pla ""; stringbuilder result = ""; stringbuilder result = ""; cry stringbuilder int to add content = 1; while ((line = br.readline ())! = Null & amp; ; Content place == - 1) {int swIndex = line.indexOf ("\" sw \ ""); Contentplace = line.indexOf ("& gt;", swIndex);} if (contentPlace & gt; -1) {// Content is the place where I have to add "index" -------- I need help here ---------- Results = br.append (adding content, Content place); -------- I need help here ----------}  

and then this jsp tag

  & Lt;% = result% & gt;  

I do not need any changes to index_012.html or any other file

I think you should do something like this
