Example 2: Indexing

Example 2: Indexing

The example of indexing by key at the start of this chapter, illustrates how to use the
target
property with indexing. The following figure illustrates how to configure the
target
property of the
RepeatingGroupMapping
:
level 2 target = level 3 Locator = >> level 4 data_holder = /Hobbies/*s/Hobby/*s/Person level 3 LocatorByKey = >> level 4 key = /Hobbies/*s/Hobby/*s[@name=1] level 4 params = /Report/*s/Children/*s/Child/@hobby level 4 ...
The
target
property identifies the following data holders:
  • A
    Locator
    component identifies an occurrence of
    Person
    . Each iteration creates a new occurrence of
    Person
    .
  • A
    LocatorByKey
    component identifies the occurrence of the
    Hobby
    element, where the occurrence of
    Person
    should be nested. If the
    Hobby
    element already exists, the transformation uses it. If the
    Hobby
    element does not yet exist, the transformation creates it.
