Optional Sections

In this example, suppose that the second section,

Professional Experience

, is missing from some input XML documents, but you want to write its separator to the output, like this:

----------------------------
Jane Palmer
Employee ID 123456
----------------------------
----------------------------
Education
...

To support this situation, configure the

DelimitedSectionsSerializer

in the following way:

In the second

GroupSerializer

, select the

optional

property. This means that if the

GroupSerializer

fails, it should not cause the

DelimitedSectionsSerializer

to fail.

In the

DelimitedSectionsSerializer

, set

using_placeholders

always

. This means to write the separator of an optional section, even if the section itself is missing.

Alternatively, suppose that if the

Professional Experience

section is missing, you do not want to write its separator:

----------------------------
Jane Palmer
Employee ID 123456
----------------------------
Education
...

In this case, configure the

DelimitedSectionsSerializer

as follows:

In the second

GroupSerializer

, select the

optional

property.

In the

DelimitedSectionsSerializer

, set

using_placeholders

never

. This means not to write the separator of a missing section.
