Adding an element with an attribute to destination schema that doesn't exist on source schema

Question

I have source schema which looks something like below:
source schema
 name                    //attribute
 address1                //attribute
 address2                //attribute
 city                       //attribute
I need to map it to a destination schema which looks like below:
destination schema
employee                  //record (repeating element)
  fieldname                //attribute
  type                       //attribute
After mapping, the xml would look like below: 
<employee fieldname= 'name' type='string'>
<employee fieldname= 'address1' type ='string'>
<employee fieldname= 'address2' type ='string'>
<employee fieldname= 'city' type ='string'>
(fieldname exists in source schema, but 'type'  doesn't. basing on the fieldname, I add it on the destination schema using ValueMapping functoid )And I am able to do it successfully, but my question is, I need to add a field called 'salary'
of type 'double' to the destination schema similar to the other values
<employee fieldname= 'salary' type ='double'>
But salary doesn't exist in 'source' schema,  and it needs to be there in destination schema associated with the attribute 'type='dcouble''   How can I accomplish this? Appreciate any help. thanks!!

Hi Anne,
For your requirement, all you need is Table Looping functiod and Table Extractor functiod.
In this example, I am not using the value mapping functiod (you can also use it, but I prefer to make this sample easier for you to understand) so using a “string” as constant.
When you mean by you want
<employee fieldname= 'name' type='string'>
<employee fieldname= 'address1' type ='string'>
<employee fieldname= 'address2' type ='string'> <employee fieldname= 'city' type ='string'>
I assume you’re looking for something like this
<employee fieldname= 'ValueOfName' type='string'>
<employee fieldname= 'ValueOfAddress1' type ='string'>
<employee fieldname= 'ValueOfAddress2' type ='string'>
<employee fieldname= 'ValueOfCity' type ='string'>
Or if you just need field names not the value of the fields, you can still do what you want with the way you do now but using Table Looping functiod and Table Extractor
functiod.
Let me explain this.
Use Table Looping functiod with following parameters:
5 = You need 5 records in output i.e. name, address1,address2,city and salary.
2 = you need 2 columns. i.e. fieldname and type.
Link from 'name' in source schema. Here I have just linked the 'name' from source schema, so this will have VALUE-of-Name element/attribute. Or if you can want just the
field name, you can use the way you’re using to get the field name.
Repeat the above step for all the rest of the fields. I have linked address1, address2 and city.
7^th parameter is “string” as constant, which I will be passing to “type” attribute in destination. Again you can use value mapping functiod as you
do. If you use value mapping functiod, then rest of the parameter shall be value mapping functiod.
Then I add last two paraters “salary” and “double” as constants, which I will be using to add the new record. Below image show the parameters for Table looping functiond:
Now select the “Configure Table Looping grid” property and map as shown. Give a closer look to the way how this grid has been mapped. Last record in the grid shows the
additional record which you want to add with “salary” and “double”
Now add “Table Extractor functiod”, set its first parameter to “Table looping” and second parameter as “1”
Now another “Table Extractor functiod”, set its first parameter to “Table looping” and second parameter as “2”. Below image show the Table Txtrator functiods parameters:
Now link the Table Looping functiod to “employee” record in destination schema.
Use the above you will get the output as you wanted. Following is the output, note: as mentioned in the fieldName attribute I have the value of the source fields/attributes
since I have used the direct link from soruce in Table Looping functiod parameters, you can use the link which is producing the value for you now for fieldname:
<employee fieldName="name_0" type="string"></employee>
<employee fieldName="address1_1" type="string"></employee>
<employee fieldName="address2_2" type="string"></employee>
<employee fieldName="city_3" type="string"></employee>
<employee fieldName="salary" type="double"></employee>
