Re: Dynamically Generate request XML

I have to dynamically create request xml based on number of rows retrieved from database.

for example


.....>
   

     

   
-- row 1
?
?
...
...
 -- row 2

?
?
...
...

I am retrieving all the rows using datasource and running a query.

Then I tried to insert new tags from the property transfer step using


Property Transfer from

declare namespace mat='http://xxxxxxxx/matterservice/';

insert   '
${Properties#CORRELATION_ID}
${Properties#MTTR_DT_NM_ID}
${Properties#MTTR_DT_TYPE_ID}
${Properties#DATE_VALUE}
'

into //mat:MatterServiceRequest[1]/MatterServiceInput[1]/UpdateMatter[1]/row[1]

Property Transfer to

declare namespace mat='http://xxxxxx/matterservice/';
//mat:MatterServiceRequest/MatterServiceInput/UpdateMatter/CreateMatterDate

But instead of inserting, it overwrites the existing values.

I know I am doing something wrong as this step should be trivial.

Can somebody point me in the right direction.

Thanks,
Abhi

    Thanks for pointing me in the right direction.

    So, I created groovy script. In the script, I expand properties derived from the database and then create an xml node and append it to the current request xml.

    Here is the code to create and append the xml node.


    //Create Node
    def xmlBuilder = new NodeBuilder()

    // Assign Values to the node
    def newNode = xmlBuilder.CreateMatterDate {
      CorrelationID('1234124' )
      if(dateNameId ==null){ DateNameID( "xsi:nil":"true")}
      else{  DateNameID( dateNameId)}
      DateType(dateType) 
      DateValue(dateValue)
    }

    //Append the node
    def node = new groovy.util.XmlParser(false,false).parseText(property.value);
    def textNodes = 
    node["soapenv:Body"]["mat:MatterServiceRequest"]["MatterServiceInput"]["UpdateMatter"][0].children()

    textNodes.add( matterNode);
    textNodes.add( newNode);


    // write back to string
    def writer = new java.io.StringWriter();
    def printer = new groovy.util.XmlNodePrinter( new PrintWriter( writer ));
    printer.print( node );

    Is there a better way to define nillable attribute instead of using if else condition as I doing? I have tried "?." operator but that didn't work.

    Thanks,
    Abhi

    Hi,

    I think you should be able to replace


    if(dateNameId ==null){ DateNameID( "xsi:nil":"true")}
      else{     DateNameID( dateNameId)}



    DateNameID( dateNameId ?: ["xsi:nil":"true"] )


    This uses the "Elvis operator" ?: to use dateNameId, unless it is null in which case the second argument will be used.
