query-e775fcd110824888ff4ad0a5c003f878
Applying regex to query. extract anything, but instead replace, but running this query (limited to just one file for testing purposes) does not return what I want; I don't think I actually want to the documentation for those functions, and read REPLACE and BIND variable, I'm stuck on trying to implement this in SPARQL. I thought I needed to use ?content to extract the strings from the the regex I need to use and obtained asked a Stack Overflow question, Thanks once again. Having Dipsacus fullonum@
