> XMLReader / ValidateRecord: arrays are not read correctly

> Key: NIFI-7969
> URL: https://issues.apache.org/jira/browse/NIFI-7969
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework, Extensions
> Affects Versions: 1.9.0, 1.12.0
> Reporter: Vesa Sokka
> Assignee: Peter Gyori
> Priority: Major
> Labels: records, validation, xml

> I'm trying to convert XML to JSON with ValidateRecord using XMLReader. Arrays
> with multiple elements work fine, but an *array with only one element fails*.
>
> In XMLReader docs it says clearly:
> _"If a field in a schema is embedded in an array, the *reader expects zero,
> one or more* occurrences of the field in a record. "_
> But in fact an array with only one field is transferred to "invalid" with an
> error message:
> "Record #1 is invalid due to:
> content1 is not a valid value for /array_field: Value is of type
> java.lang.String but was expected to be of type ARRAY[STRING]"
>
> examples modified from:

> _Both examples have same schema_;
> {code:json}

> *Example 1* (success)
> {code:xml}
> <record>
> <array_field>content1</array_field>
> <array_field>content2</array_field>
> </record> {code}
> --> *valid*+:+
> {code:json}
> [{"array_field":["content1","content2"]}]
> {code}
>
> *Example 2* (invalid):
> Same as example 1, but the second array_field removed
> {code:xml}
> <record>
> <array_field>content1</array_field>
> </record>
> {code}
> --> *invalid*
> {code:json}
> [{"array_field":"content1"}]{code}

> *Seems to be a BUG or is this an error in the processor documentation?*
