How to create a node with attribute?

hi,
does anyone can help with creating an XML node with only attributes but no value?
e.g.
<root>
   <category node_id='ND1'>
      <value id='1'>some value in here</value>
      *<extra_node desc="this is the new node i want to create"/>*
   </category>
   <category node_id='ND2'>
      <value id='1'>some value in here</value>
   </category>
</root>in the example, what i want to do is to get the category using XPath, and insert one attribute node into it.
anyone can help? sincerely appreciated!

No, the question was not about attributes with no value, it was about elements with no value.
Now I know that the "value" of an element is a meaningless term in XML, but the OP's example shows that the question was how to produce an empty element. Even though the text describes the operation as "insert one attribute node", which doesn't agree with the example.
It's easy to create an empty element using DOM, but we have no idea whether the OP is talking about DOM programming or what.

Hi Experts,

I even check IF_WD_CONTEXT_NODE but i could not find any method that creates a node with attribute.

I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition

Create dinamic nodes and attributes

Hi Forum!
I have created a WDA with 2 views. On the START_VIEW, the user can input details from an installation. I want to display an error on the START_VIEW when a condition is false.
How I can create a node with an attribute dinamically to display this error if the message Text View is not defined on the view?
Could you give me a any sample of code, please?
Thank you very mucha and regards,
Manuel.

Hi Manuel,
Pleaes try this out. This is how to create an attribute dynamically.
DATA: attribute TYPE wdr_context_attribute_info.
DATA: main_node TYPE REF TO if_wd_context_node_info.
"get main node
main_node = wd_context->get_node_info( ).
"set name for this attribute
attribute-name = 'SOME_NAME_4_ATTR'.
"set data type for this attribute

How can create a JTree with cellRender is checkbox realized multiple selec

How can create a JTree with cellRender is checkbox realized multiple selection function.thanks for every
one's help.

Hi,
1. Create a value node in your context name Table and set its cardinality to 0:n
2. Create 2 value attributes within the Table node name value1 and value2
3. Goto Outline view> Right click on TransparentUIContainer>Apply Template> Select Table>mark the node Table and it's attributes.
you have created a table and binded its value to context
Table UI properties
4.Set Selection Mode to Multi
5.Set Visible Row Count to 5
6.ScrollableColCount to 5
In your implemetaion, you can add values to table as follow:
IPrivate<viewname>.ITableElement ele = wdContext.nodeTable().createTableElement();
ele.setValue1(<value>);
ele.setValue2(<value>);
wdContext.nodeTable().addElement(ele);
The above code will allow you to add elements to your table node.

I need your expert opinion on how to create a map with multiple conditions.

Hello.
I need your expert opinion on how to create a map with multiple conditions.
I have a procedure (which i cannot import or re-create in OWB due to the bug), so i am trying to create a map instead :-(
How can i create a cursors within the map?
My function creates table and cursor.
Then it will have to check for duplicates in the tables (the one created and another table) - the criteria for finding duplicates is a number of fields.I then need to place few different conditions (if some attributes are not available) and it has to load cursor based on this conditions. The next step is to fetch the data into the cursor based on what attributes are missing.
The next thing it will do is insert the data into table (if record doesn't exist), output the error in separate table is record is corrupted, or update the record with changed information.
In short i need to re-create match / merge but with conditions, iterations etc 'built into' it.
I can read up on available functions - it's just what would be the best options? and what would be the best approach to do so?
In my function i use %rowtype - but cannot use it in owb - so what would be the alternative? i don't really want to create a lot of variables and then have a nightmare of maintaing it. are there any tips regarding this?
having looked through Oracle dedupe - it's not really what i need because it is just DISTINCT.
I would appreciate any help / advise on this.
Thank you very much

thanks a lot for your reply - i will look into this option :-)
it is a bit more complicated now as i have to re-create the match / merge and then somehow 'tweak' it to achieve the result i need.
At the moment i am looking to breakdown the package into smaller chunks 'functions' and try creating the map that way.
Anyway, thank you very much for your suggestion.

How to create a window with its own window border other than the local system window border?

How to create a window with its own window border other than the local system window border?
For example, a border: a black line with a width 1 and then a transparent line with a width 5. Further inner, it is the content pane.
In JavaSE, there seems to have the paintComponent() method for the JFrame to realize the effect.

Not sure why your code is doing that. I usually use an ObjectProperty<Point2D> to hold the initial coordinates of the mouse press, and set it to null on a mouse release. That seems to avoid the dragging being confused by mouse interaction with other nodes.

Hi Easwar
Thanks a lot for answering the question.
Yes I do have CRM Billing documents. But the problem is
a) either the billing document doesn't have Transfer to Accounting status Transferred or
b) a transferred billing document, but all items have error "Unable to offset billing item 90003458 0000000060" etc.
Do you know
1) how I can make a billing document have "Transferred" status? Pressing "Transfer to Accounting" button in the billing document overview page will only set the status to "Being transferred". And it's always being tranfered.
2) What does the error "Unable to offset billing item ... "mean? How to get rid of them?
Thanks a lot!

I am creating XML file using DBMS_XMLGEN package. This XML file will contain data from two different database tables. So I am creating temporary table in the PL/SQL procedure to have the data from these different tables in a single temporary table.
Please find the below Dynamic SQL statements that i'm using for create the temp table and inserting the data into it.
Before insert the V_NAME filed, i will be appending a VARCHAR field to the original data.
EXECUTE IMMEDIATE 'CREATE TABLE TEMP_TABLE (UNIQUE_KEY NUMBER , FILE_NAME VARCHAR2(1000), LAST_DATE DATE)';
EXECUTE IMMEDIATE 'INSERT INTO TEMP_TABLE values (SEQUENCE.nextval,:1,:2)' USING V_NAME,vLastDate;What exactly i need is to eliminate the INSERT portion of it,Since i have to insert more 90,000 rows into it. Is there way to have the temp table created with data in it along with the sequence value as well.
I'm using Oracle 10.2.0.4 version.
Edited by: 903948 on Dec 22, 2011 10:58 PMWhat you need to do to eliminate the INSERT statement is to -- as already suggested by others - eliminate the temporary table. You don't need it. It is just necessary overhead. Please explain why you (apparently) believe that the suggestion of a view will not meet your requirements.
