Peter Gyori created NIFI-9831:
---------------------------------
Summary: 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
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.
