Apache NiFi Replace Text processor to use control character as delimiter

问题

Using replace text processor while converting fixed width file to delimited with normal character like ';' , '|' ,',' as delimiters is working. However considering \u0001 or [^]A or \^A is not working as expected.

回答1:

to use special chars you could use literal + unescapeXml nifi expression functions:

${literal(''):unescapeXml()}
