Peter Gyori updated NIFI-9831:
------------------------------
Status: Patch Available (was: In Progress)
> XMLReader adds extra XML element to the schema if the input contains XML
> attribute
> ----------------------------------------------------------------------------------
>
> Key: NIFI-9831
> URL: https://issues.apache.org/jira/browse/NIFI-9831
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Peter Gyori
> Assignee: Peter Gyori
> Priority: Major
> Labels: inference, reader, schema, xml
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Let's use a ConvertRecord processor with an XMLReader to process XML
> documents. Let's set the reader's 'Schema Access Strategy' property to 'Infer
> Schema'. The processor can be configured with any writer, we just need to
> make sure the record schema is written in an attribute to the outgoing
> flowfile.
> XMLReader controller service settings:
> * Schema Access Strategy: Infer Schema
> * Expect Records as Array: false
> ConvertRecord processor settings:
> * Record Reader: XMLReader
> * Record Writer: any writer with _Schema Write Strategy: Set 'avro.schema'
> Attribute_ and _Schema Access Strategy: Inherit Record Schema_
> Input data:
> {code:java}
> <record>
> <num>123</num>
> <software favorite="true">Apache NiFi</software>
> </record>{code}
> Output schema:
> {code:java}
> {
> "type": "record",
> "name": "nifiRecord",
> "namespace": "org.apache.nifi",
> "fields": [
> {
> "name": "num",
> "type": [
> "null",
> "int"
> ]
> },
> {
> "name": "software",
> "type": [
> "null",
> {
> "type": "record",
> "name": "softwareType",
> "fields": [
> {
> "name": "favorite",
> "type": [
> "null",
> "boolean"
> ]
> },
> {
> "name": "value",
> "type": [
> "null",
> "string"
> ]
> }
> ]
> }
> ]
> },
> {
> "name": "favorite",
> "type": [
> "null",
> "boolean"
> ]
> }
> ]
> }{code}
> In the output schema the record/favorite element is unexpected.
