Write a DataFrame to XML and read it back as a stream:

Python

import tempfile
import time
with tempfile.TemporaryDirectory(prefix="xml") as d:
    spark.createDataFrame(
        [{"age": 100, "name": "Hyukjin Kwon"}]
    ).write.mode("overwrite").option("rowTag", "person").xml(d)
    q = spark.readStream.schema(
        "age INT, name STRING"
    ).xml(d, rowTag="person").writeStream.format("console").start()
    time.sleep(3)
    q.stop()
