Preconditions
For the content precond of attribute using of an element tt:cond , you can specify the following preconditions. The operand of the precondition can be a data node specified in the form dnode .
State Queries
|
Precondition |
Meaning |
|---|---|
|
exist( dnode ) |
Met if an ABAP data object is bound to the node |
|
type-C( dnode ) |
Met if an ABAP data object of type c is bound to the node |
|
type-D( dnode ) |
Met if an ABAP data object of type d is bound to the node |
|
type-F( dnode ) |
Met if an ABAP data object of type f is bound to the node |
|
type-I( dnode ) |
Met if an ABAP data object of type i is bound to the node |
|
type-N( dnode ) |
Met if an ABAP data object of type n is bound to the node |
|
type-P( dnode ) |
Met if an ABAP data object of type p is bound to the node |
|
type-T( dnode ) |
Met if an ABAP data object of type t is bound to the node |
|
type-X( dnode ) |
Met if an ABAP data object of type x is bound to the node |
Example
The element X is considered during serialization only if the ABAP data object bound to ROOT is of type c .
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT"/>
<tt:template>
<tt:s-cond using="type-C(ref('ROOT'))">
<X>
...
</X>
</tt:s-cond>
</tt:template>
</tt:transform>
Instead of "type-C(ref('ROOT'))" , you could also write "type-C(ROOT)" .
Linking Several Preconditions
You can specify a precondition as a list of several of the above preconditions, separated by commas. Such a precondition is met if all preconditions in the list are met. Within the list, every data node may appear only once.
Example
The element X is considered during serialization only if the ABAP data object bound to ROOT1 is of type i and the ABAP data object bound to ROOT2 is of type f .
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT1"/>
<tt:root name="ROOT2"/>
<tt:template>
<tt:s-cond using="type-I(ROOT1), type-F(ROOT2)">
<X>
...
</X>
</tt:s-cond>
</tt:template>
</tt:transform>
