            res = Integer.valueOf(results.getAttributes().getNamedItem("count").getNodeValue());
        }catch(Exception e ){

    public static String getValue(Element item, String str) {

        return XMLfunctions.getElementValue(n.item(0));
    }


    public static String html2text(String html) {

        String pText = Jsoup.clean(html, Whitelist.basic());
        return pText;
    }

}

I call these function like

String xml = XMLfunctions.getBodyXML(id);

Document doc = XMLfunctions.XMLfromString(xml);

i want that the font tag be there as html tag in xml.

help would be appreciated!!!!!


Enclose your HTML in a CDATA section so it doesn't get treated as part of your XML, but instead just normal text:

<result>
<![CDATA[
    <body><font size="2px" face="arial">Hello World</font></body>
]]>
</result>

Update

Your problem is probably here:

sb.append("<result>\r\n");
    sb.append("<body>");
    String tmpText = html2text(text.toString());
        sb.append("<![CDATA[<body>");
        sb.append(tmpText);
        sb.append("</body>]]>");
    sb.append("</body>\r\n");
sb.append("</result>\r\n");

Notice the sb.append("<body>"); and sb.append("</body>\r\n"); lines surrounding your CDATA section, they're probably causing the problem with your XML not being read correctly. Maybe you should remove those two lines so it looks like this:

sb.append("<result>\r\n");
    String tmpText = html2text(text.toString());
    sb.append("<![CDATA[<body>");
    sb.append(tmpText);
    sb.append("</body>]]>");
sb.append("</result>\r\n");
