How to display an XML in Web Dynpro

Question

Hi,
I am pretty new to Web Dynpro and have a specific requirement.
I have a web dynpro page on which we display a table. One of the columns in the table is a XML message. Now on lead selection of each row I want to display the contents of the XML in an embedded control below the table. I have already implemented the functionality to download the XML message to file system but I want a capability to show the XML contents within my page in a formatted way.
If I use a text view, the XML does not look very nice.
I do not want to implement a new tree control based control now where I parse my xml file and then try to recursively generate a tree. This will take time for me as i am not very well versed with WD programming.
Can anyone tell me if there exists any control in WD which can display the XML in formatted way?
If you guys have used the new ABAP debugger and seen the XML viewer in it then you can get an idea of what I need. I am not sure about the control that the ABAP debugger uses. It will be good if someone can help me find something like that.
After all WD is all about reusability.

Hi Vikas,
   see this little example which creates a xml file to download and open in the browser. Put it in an action handler method.
DATA lr_conv   TYPE REF TO cl_abap_conv_out_ce.
  DATA lv_data   TYPE        string.
  DATA lv_xfile  TYPE        xstring.
  lv_data = '<?xml version=1.0" encoding="utf-8"?> put your xml here'.
  cl_abap_conv_out_ce=>create( RECEIVING conv = lr_conv ).
  lr_conv->convert( EXPORTING data   = lv_data
        IMPORTING buffer = lv_xfile ).
  cl_wd_runtime_services=>attach_file_to_response(
                 EXPORTING
                     i_filename  = 'test.xml'
                     i_content   = lv_xfile
                     i_mime_type = 'application/xml' ).
Hope this helps you. Revert if need some more help.
