How would i retrieve data JSON data with namespaces using spark SQL?

File.json from the below code contains huge JSON data with each key containing namespace prefix(This JSON file converted from the XML file).

I could able to retrieve if JSON does not contain namespaces but what could be the approach to retrieve records/values if each key is with a namespace prefix?

jsondf = spark.read.json("<path>/file.json")
 
#jsondf.printSchema()
jsondf.createOrReplaceTempView("ramp")
 
elements = spark.sql("SELECT * FROM ramp")
elements.show()
 

Here,I wanted to retrieve records of w: document/w.body/w:p. I tried different ways but nothing is working. Any suggestions really helpful

HI @Ramesh Bathini​ ,

not sure what you have tried, but maybe you can try this way:

 select `w:document`.`w.body`.`w:p` from ramp
