Modify elemets of a node

Question

Hi Experts,
I am trying to enhance method HANDLE_UPLOAD_CHILDREN of class /SAPSRM/IF_CLL_SOSM_SC_TEMPL in SRM 7.0  .
Let me explain the issue
Time point 1.
lon_results_node = mo_wd_context->get_child_node( mc_data_results_node ).
In debugger
COLLECTION                                        Standard Table[18x1(8)]
Time point 2.
lon_results_node->bind_table(
       EXPORTING
       set_initial_elements = abap_false
       new_items = lt_cll_result ).
In debugger
COLLECTION                                        Standard Table[22x1(8)]
My requierment is to change the data of one column in the internal table lt_cll_result  and this changes data should be displayed in UI.
I get relevant data into column for all rows in lt_cll_result  and then bind it again but this adds to existing 22 redords instead of modifying the elements of node.
How can I modify the elements?
I tried to INVALIDATE the node before binding again but doing this nthing is displayed in UI (table is initial messgae), also tried passing SET_INITIAL_MELEMENTS = ABAP_TRUE but same result.
Thanks,
Anubhav

Without the dtd, it is not clear why the sample code fails but here are a few pointers that may be of use:
- The j2ee tutorial on java.sun.com:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPDOM5.html#wp64575
has a section on 'examing the structure of a dom' .
Excerpt for the above URL:
Note: Important! Text nodes exist under element nodes in a
DOM, and data is always stored in text nodes. Perhaps the most
common error in DOM processing is to navigate to an element
node and expect it to contain the data that is stored in that
element. Not so! Even the simplest element node has a text
node under it that contains the data. For example, given
<size>12</size>, there is an element node (size), and a text
node under it that contains the actual data (12).
http://java.sun.com/j2ee/1.4/docs/tutorial/examples/jaxp/dom/samples/DomEcho02.java is a useful program to analyze the structure of a dom.
- You can try printing the DOM and analyse the structure of DOM. The following URL has a set of useful samples for xml dom processing: http://developers.sun.com/sw/building/codesamples/dom/. In particular the DOMUtils class has two useful static methods for debugging a DOM:
1. printDOM(org.w3c.dom.Node node): Prints the specified node, then prints all of its children.
2. writeXmlToFile(java.lang.String filename, org.w3c.dom.Document document): This method writes a DOM document to a file
http://developers.sun.com/sw/building/codesamples/dom/doc/DOMUtil.java
- http://forum.java.sun.com/forum.jspa?forumID=34 is the forum for java technology & xml.
Hope u find the pointers useful.
