you may need header information to convert this to json, technically even the xsl output you have is CSV, just delimited with pipe. I think you can directly use the executescript processor, to call a python script, and go from xsl to json..
getfile (read the file with xsl data ) -> splittext (split the data into lines )-->execute script (with script below to convert to json) --> merge content (merge contents based on fragment.identifier attribute of split text) --> put file (gives you json files )
--- example scrip for converting to json..
import json
import java.io
from org.apache.commons.io import IOUtils
from java.nio.charset import StandardCharsets
from org.apache.nifi.processor.io import StreamCallback
class PyStreamCallback(StreamCallback):
def __init__(self):
pass
def process(self, inputStream, outputStream):
header=["column1","column2","column3"...] # the header for the xsl, this will become the name for json nodes
text = IOUtils.toString(inputStream, StandardCharsets.UTF_8)
output={}
for column in text.split("|"):
index=0 # counter to keep track of column, so we can assing a name to the value.
output[header(index)]=column
outputStream.write(bytearray(json.dumps(output, indent=4).encode('utf-8')))
flowFile = session.get()
if (flowFile != None):
flowFile = session.write(flowFile,PyStreamCallback())
flowFile = session.putAttribute(flowFile, "filename", flowFile.getAttribute('filename').split('.')[0]+'_translated.json')
session.transfer(flowFile, REL_SUCCESS)
