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"

我创建了一个函数来解析 xhtml 代码并删除不受欢迎的标签并添加到 css 文件“tableStyle.css”的链接

    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(" ", "");
            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?

但作为一个性能问题，它好吗？

by the way it works will

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

当输入也被视为 XML 时，我只取得了成功。所以要么将 xmltags 设置为 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.

并忍受错误和警告，或者进行两次转换。第一次转换以清理 html（html 到 xhtml），然后使用设置的 xmltags 从 xhtml 到 xhtml 的第二次转换，因此不会发生错误和警告。

        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.

You can use the following method to get xhtml from html

您可以使用以下方法从 html 中获取 xhtml

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;
    }
