cdata-section-elements to serialize data with CDATA

I am using textarea controls in my XFORM and I wanted to keep the carriage
return, spaces, etc. with my xml data serialized. While submitting the form, I
have used cdata-section-elements attribute and also passed the element
reference but still it is not working

My .XHTML looks like this

<?xml version="1.0" encoding="iso-8859-1"?>
<xhtml:html xmlns:ev="http://www.w3.org/2001/xml-events"

                        <xforms:group
                                ref="instance('medwatch')/groupone"
                                        appearance="full">
                                <font face="Verdana"  size="2" ><b>Text Area

                                        <br  />
                                        <xforms:textarea xmlns=""

                                </font>

                        </xforms:group>
               
                <xforms:submit submission="save">
                        <xforms:label>Submit</xforms:label>  
                </xforms:submit>

</xhtml:body>
</xhtml:html>
 
XFormSave is a servlet and in my do post, I had the following lines of code to
get the data of form submitted

                BufferedReader requestData = new BufferedReader(new
InputStreamReader(request.getInputStream()));
                StringBuffer stringBuffer = new StringBuffer();
                String line;
                try{
                while ((line = requestData.readLine()) != null) {
                        stringBuffer.append(line);
                        }
                } catch (Exception e)
                {
                        e.printStackTrace();
                }

and finally, I will get the xml file in my StringBuffer. But, I am not able to
get data with CDATA sections.

Pl. inform me what is wrong in my approach

Sabeer

I ran your example locally, enter "a" two carriage returns and "b". In the body of the POST, I do see the two carriage returns as expected:



Have you tried to look at the HTTP traffic in your case?

Hi Alex,
Thanks for the reply.
What should be done if I need the xml data from the xform submitted with CDATA
sections.
I would like to get the data like this

<?xml version="1.0" encoding="UTF-8"?>
<data xmlns:xhtml="http://www.w3.org/1999/xhtml"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:ev="http://www.w3.org/2001/xml-events"
      xmlns:xforms="http://www.w3.org/2002/xforms">
                               
<textareafield1><![CDATA[a

b]]></textareafield1>
                                        <groupone>
                                                  <textareafield2><![CDATA[a

b]]></textareafield2>
                                        </groupone>
                                </data>

I have already included cdata-section-elements in my submission

In my Servlet, I am using the following code to retrieve the data

BufferedReader requestData = new BufferedReader(new
InputStreamReader(request.getInputStream()));
StringBuffer stringBuffer = new StringBuffer();
String line;
try{
while ((line = requestData.readLine()) != null) {
stringBuffer.append(line);
}
} catch (Exception e)
{
e.printStackTrace();
}

For my application requirements, I have to use the servlet to get the data

Sabeer

You can't specify that you want a:

<textareafield1>

<![CDATA[a
b]]>

</textareafield1>

instead of a:

<textareafield1>a
b</textareafield1>

Both represent the same XML info set, and it shouldn't matter which one the <xforms:submission> sends. The CDATA is more of convenience for humans to escape a block that shouldn't be interpreted as XML. Say if you put HTML inside an element but don't want the HTML tags to be interpreted as XML elements; without the CDATA you'd have to escape all the < into &lt;.
