JTidy java API toConvert HTML to XHTML

Question

I am using JTidy to convert from HTML to XHTML but I found in my XHTML file this tag  . Can i prevent it ?
this is my code

    //from html to xhtml
   try   
    {  
        fis = new FileInputStream(htmlFileName);  
    }  
    catch (java.io.FileNotFoundException e)   
    {  
        System.out.println("File not found: " + htmlFileName);  
    }  
        Tidy tidy = new Tidy(); 
        tidy.setShowWarnings(false);
        tidy.setXmlTags(false);
        tidy.setInputEncoding("UTF-8");
        tidy.setOutputEncoding("UTF-8");
        tidy.setXHTML(true);// 
        tidy.setMakeClean(true);
        Document xmlDoc = tidy.parseDOM(fis, null);  
    try  
    {  
        tidy.pprint(xmlDoc,new FileOutputStream("c.xhtml"));  
    }  
    catch(Exception e)  
    {  
    }

take care with .setMakeClean, as it may cause <div> and <span> tags to be merged, for instance. — PypeBros

I had only success, when the input is treated as XML as well. So either set xmltags to true

 tidy.setXmlTags(true);

and live with the errors and warnings or do the conversion twice. First conversion to sanitize the html (html to xhtml) and a second conversion from xhtml to xhtml with set xmltags, thus no errors and warnings occur.

        String htmlFileName = "test.html";
    try( InputStream in = Thread.currentThread().getContextClassLoader().getResourceAsStream(htmlFileName);
         FileOutputStream fos = new FileOutputStream("tmp.xhtml");) {
        Tidy tidy = new Tidy();
        tidy.setShowWarnings(true);
        tidy.setInputEncoding("UTF-8");
        tidy.setOutputEncoding("UTF-8");
        tidy.setXHTML(true);
        tidy.setMakeClean(true);
        Document xmlDoc = tidy.parseDOM(in, fos);
    } catch (Exception e) {
        e.printStackTrace();
    }

    try( InputStream in = new FileInputStream("tmp.xhtml");
         FileOutputStream fos = new FileOutputStream("c.xhtml");) {
        Tidy tidy = new Tidy();
        tidy.setShowWarnings(true);
        tidy.setXmlTags(true);
        tidy.setInputEncoding("UTF-8");
        tidy.setOutputEncoding("UTF-8");
        tidy.setXHTML(true);
        tidy.setMakeClean(true);
        Document xmlDoc = tidy.parseDOM(in, null);
        tidy.pprint(xmlDoc, fos);
    } catch (Exception e) {
        e.printStackTrace();
    }

I used the latest jtidy version 938.

i created a function that parse the the xhtml code and remove the unwelcome tags and to add a link to the css File "tableStyle.css"

    public static  String xhtmlparser(){ 
    String Cleanline="";

    try { 
        // the file url
        FileInputStream fstream = new FileInputStream("c.xhtml");
        // Use DataInputStream to read binary NOT text.
        BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
        String strLine = null;
        int linescounter=0;
        while ((strLine = br.readLine()) != null)   {// read every line in the file             
            String m=strLine.replaceAll("&nbsp;", "");
            linescounter++;
            if(linescounter==5)
                m=m+"\n"+ "<link rel="+ "\"stylesheet\" "+"type="+ "\"text/css\" "+"href= " +"\"tableStyle.css\""+ "/>";
            Cleanline+=m+"\n";
        }

    }
    catch(IOException e){}

    return Cleanline;
}

but as a performance issue is it good?

by the way it works will

You can use the following method to get xhtml from html

public static String getXHTMLFromHTML(String inputFile,
            String outputFile) throws Exception {

        File file = new File(inputFile);
        FileOutputStream fos = null;
        InputStream is = null;
        try {
            fos = new FileOutputStream(outputFile);
            is = new FileInputStream(file);
            Tidy tidy = new Tidy(); 
            tidy.setXHTML(true); 
            tidy.parse(is, fos);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }finally{
            if(fos != null){
                try {
                    fos.close();
                } catch (IOException e) {
                    fos = null;
                }
                fos = null;
            }
            if(is != null){
                try {
                    is.close();
                } catch (IOException e) {
                    is = null;
                }
                is = null;
            }
        }

        return outputFile;
    }
