> 'Attribute Prefix' property should set to a specific prefix for parsed
> attributes using the XMLReader controller service, when 'Parse XML
> Attributes' property is set to true, and the schema is inferred.
> Unfortunately when a prefix is set, it seems that the original attribute
> names are used and the value is set to null.
> Example with ConvertRecord processor using XMLReader as the record reader and
> JsonRecordSetWriter as record writer:
>
> Properties:
> Parse XML Attributes: true
> Attribute Prefix: attr_
> Field Name for Content: tagval
> Input:
> {code:java}
> <note>
> <to alias="Toto">Thomas Mills</to>
> </note>
> {code}
> Expected result:
> {code:java}
> [{"to":{"attr_alias":"Toto","tagval":"Thomas Mills"}}] {code}
> Actual result:
> {code:java}
> [{"to":{"alias":null,"tagval":"Thomas Mills"}}] {code}
