I am reading a html file using an inputstream from a java servlet. But the contents of the original and the read one are in a different format although when displayed in a web browser they are the same. These are the two links for the html files after reading output http://www.fileflyer.com/view/gQREGAe orginal output http://www.fileflyer.com/view/mWXHVAE Is there a way to get the original html when reading? why is this happening? my java code is as follows;

InputStreamReader isr = new InputStreamReader(inputStre开发者_如何转开发am);
     BufferedReader br = new BufferedReader(isr);
     String line = null;
     while ( (line = br.readLine()) != null)
     {
      System.out.println(line);
}

Any help would be greatly appreciated!!

Thank you, rana.

The one in different format (the one named extracted.html) is clearly generated by Microsoft Word.

<html xmlns:v="urn:schemas-microsoft-com:vml"
      xmlns:o="urn:schemas-microsoft-com:office:office"
      xmlns:w="urn:schemas-microsoft-com:office:word"
      xmlns:m="http://schemas.microsoft.com/office/2004/12/omml"
      xmlns="http://www.w3.org/TR/REC-html40">

Your problem is more in the source of the InputStream, not in the Java or Servlet side. They do for sure not randomly change the content of the InputStream without your intervention.

You seem to be using MS Word as a HTML editor, you should not do that, there it is not for. Rather use a textbased editor like Notepad, Notepad++, Editplus, etc for HTML editing.

I have seen both the html files. The extracted.html obviously has more tags/comments/css info that you doesn't seem to be interested. So, the only option you are left with is to use 1 of the below parsers and remove the unnecessary nodes/attributes you doesn't require (or just extract what you need)
