You can use transformers in serialization anchors that write to the output document, such as

ContentSerializer

. The transformers modify the data before the serializer writes it to the document.

For example, a

ContentSerializer

might write the content of a data holder called

DoctorName

to an output document. You might configure the

ContentSerializer

with an

AddString

transformer that adds the prefix

"Dr. "

to the content. Suppose the XML input has the following form:

The transformer modifies the content, resulting in the following output:

You can add transformers to the

default_transformers

property of a serializer. The transformers that you add here run in all the

ContentSerializer

serialization anchors before they write to the output document.
