## xte_nodebld_final

Corrects input vector
xte_nodebld_final (inout arg any, [in head any]);
Description

By default this function reduces all last empty items from the first argument and returns it, but supplyed a second argument it also replaces the first item of the first argument by the second argument, but does not commit the return.

Parameters
arg – The vector created by the xte_nodebld_init() and filled by xte_nodebld_acc() function
head – A vector returned by xte_head() function
Errors

SQLState | Error Code | Error Text | Description
--- | --- | --- | ---
22003 | SR347 | Too few arguments for xte_nodebld_final |
22003 | SR348 | The first argument of xte_node_nodebld_final is not made by xte_nodebld_init() function |

Examples
xte_nodebld_final() with a single argument.

Before the xte_nodebld_final() call the length of the vector acc is equal to 16, after the call the length is 3. The vector acc does not correspond to a xml document - there is no a root tag. The result of the xte_nodebld_final() may be used as argument for xte_node_from_nodebld() to get a vector corresponding to complete xml document.

    create procedure test1_nodebld()
                  {
                    declare acc any;
                    xte_nodebld_init (acc);
                    xte_nodebld_acc (acc,'string1', string2');
    		xte_nodebld_acc(acc, 'string3',xte_node(xte_head ('supplier', 'CompanyName','Seller')));
            	acc:=xte_nodebld_final(acc);
    	         	    . . .
    	      }

xte_nodebld_final() with two arguments.

The vector acc below is corresponding to the following XML element:

<product>string1string2string3

<supplier CompanyName="Seller"></supplier>

</product>

    create procedure test2_nodebld()
                  {
                    declare acc any;
                    declare "Res" any;
                    declare "ResLen" integer;
                    result_names ("ResLen", "Res");
                    xte_nodebld_init (acc);
                    xte_nodebld_acc (acc,'string1', 'string2');
                    xte_nodebld_acc(acc, 'string3',xte_node(xte_head ('supplier', 'CompanyName','Seller')));
            	xte_nodebld_final(acc, xte_head('product'));
    		result (length(acc), xml_tree_doc (acc));
    	      }
    test_nodebld()
    ResLen      Res
    INTEGER     VARCHAR
    _______________________________________________________________________________
