Nifi How To Insert Xml Whole Content Into Json Attribute Stack Overflow

Nifi How To Insert Xml Whole Content Into Json Attribute Stack Overflow I am trying to insert the whole content of a row of an xml file into a json attribute (i am a newbie). i am doing it this way (tell me if there is an easier way, it's good to now): i have configured extract text this way: and to finish, i configure the replace text, giving a json format:. I have a nifi flow that among other things transforms xml into json. this is done to prep the data for inserting into mongodb. i'm using the transformxml processor and an xsl to do the transform. is this the correct method? ordinarily, i would say that xslt is not the best way to transform xml to json but it wasn't able to find another way in nifi.

Nifi How To Insert Xml Whole Content Into Json Attribute Stack Overflow I would recommend using the convertrecord processor to convert the xml to json convertrecord processor. i am not the most familiar with using it for xml, but have used it for converting csv to json and it works flawlessly. In nifi, i'm trying to utilise the splitrecord processor to change incoming xml files to json. the structure of the xml file is as follows: i want to split each record but i also was to have the attributes of the field represented instead of just field itself being one giant array with no identifier. You can do it with a pure nifi flow, the steps to do this are: convert the xml to json, this can be done with a validaterecord processor, you must define the schema of the json, so during this step you are going to check that the input data is ok. modify the json structure using the jolttransform processor. I am using nifi to load data from database a in json record format and want to insert json record into a json column of a table in database b. a => executesqlrecord => [jsonrow, ] => [?] => b.table(data json).

I am using nifi to load data from database a in json record format and want to insert json record into a json column of a table in database b. a => executesqlrecord => [jsonrow, ] => [?] => b.table(data json). I am trying to run a very simple conversion flow that takes an input xml document and converts it to json using an avro schema. i must be doing something very wrong because i always get null values for even something simple like this:. For example in ms sql you can use openjson function to transpose json into table and then you can use this table in your query. for the second point, this is because the way the extracttext reg expression work it treats like group, so beside the main attribute you will get an indexed attribute for each matched group. Here is a groovy script that expects a "flat" json file and turns all the fields in into attributes: import java.nio.charset.* return; { inputstream > def text = ioutils.tostring(inputstream, standardcharsets.utf 8) def obj = slurper.parsetext(text) obj.each {k,v > attrs[k] = v.tostring() } as inputstreamcallback) @sherif eldeeb. You can use evaluatejsonpath to extract the one particular value of the input json into an attribute, then you can use replacetext to create a sql statement (using nifi expression language and group referencing, see replacetext documentation for more details) that refers to both the extracted attribute and the incoming flow file content.
