xml - 如何返回序列化的 XML 文件（XOM 文档），以便我可以在浏览器中显示它？

Question

这会在控制台上打印出我的 xml 文档，并带有漂亮的打印效果。

//writing output to a file    
Document writeDocument = new Document(document);
//Formatting the file
Serializer serializer = new Serializer(System.out, "UTF-8");
serializer.setIndent(4);
serializer.write(writeDocument);

我需要返回相同的 xml 文档，以便在浏览器中显示它。

我的一个应用程序有完全相同的要求。您可以通过获取序列化的 XOM 文档、将其包装在代码标签中并转义尖括号来完成此操作。下面的示例代码显示了一种方法：

     public String getHTMLDoc(Document document) {
        try {
            // create a new div to hold your document
            StringBuilder sb = new StringBuilder("<div id=\"xom\" style=\"font-family: 'Courier New', monospace; white-space: pre-wrap\"><pre>\n");
            // Create an array of strings with one string for each line in the document
            ByteArrayOutputStream bout = new ByteArrayOutputStream();
            Serializer writer = new Serializer(bout, "UTF-8");
            writer.setIndent(4);
            writer.write(document);
            writer.flush();
            String xomString = bout.toString("UTF-8");
            String[] lines = xomString.split(writer.getLineSeparator());
            for (int i = 0; i < lines.length; i++) {
                sb.append(convertLine(lines[i]));
            }
            sb.append("</pre></div>\n");
        } catch (IOException ex) {
            // handle the error
        }
        return sb.toString();
    }

    private String convertLine(String s) {
        // wrap the line in a code tag
        StringBuilder sb = new StringBuilder("<code>");
        // Remove trailing whitespace
        Pattern trailingWhiteSpace = Pattern.compile("[ \t\n\f\r]+$");
        Matcher m = trailingWhiteSpace.matcher(s);
        sb.append(m.replaceAll(""));
        // Change all angle brackets "<" and ">"
        sb.append(line.replaceAll(">", "&gt;").replaceAll("<", "&lt;"));
        sb.append("</code>\n");
        return sb.toString();
    }
