Description

Let's use a ConvertRecord processor with an XMLReader and an XMLRecordSetWriter to process XML documents.

XMLReader controller service settings:

• Schema Access Strategy: Infer Schema
• Expect Records as Array: false

XMLRecordSetWriter controller service settings:

• Schema Access Strategy: Inherit Record Schema

ConvertRecord processor settings:

• Record Reader: XMLReader
• Record Writer: XMLRecordSetWriter

Input data:

<record>
  <num>123</num>
  <software favorite="true">Apache NiFi</software>
</record> 

Output:

<record>
  <num>123</num>
  <software>
    <favorite>true</favorite>
    <value></value>
  </software>
  <favorite></favorite>
</record> 

The value "Apache NiFi" is lost.

(The issue of the additional "favorite" xml element is covered in https://issues.apache.org/jira/browse/NIFI-9831)
