I am working with the ReplaceText processor to replace only some instances of a double quote character (") in a FlowFile and I am having difficulty with my Regex syntax. Background: I am pulling an XML column from our database using ExecuteSQL which converts the results to Avro format. I run this through an AvroToJson processor but the JSON produced does not correctly escape double quotes found in my DB columns. I am converting to JSON because my end goal is to have the XML values in a FlowFile, line by line. Example: [ { "XML": "<MyXML> This is a "test" XML </MyXML>" } ] As you can see the quotes surrounding "test" are invalid and need to be escaped to be: [ { "XML": "<MyXML> This is a \"test\" XML </MyXML>" } ] I am trying to achieve this with the ReplaceText Processor. Using Regex I can correctly retrieve all the text between the <MyXML> tags but I am unable to single out the double quotes for replacement. I have attempted to use back-references to replace the value in the middle capturing group, but that does not appear to work. Am I able to achieve this or do I need to be looking at an ExecuteScript processor and attempting it with Python/Groovy? Sample processor config: ... View more
