I just want to get the part in bold and created a Regex to select this part. My idea is to replace the complete string and just keep the string part with the coordinates (bold part).
My Regex: rijksdriehoekX":[0-9]{6}.[0-9]{3},"rijksdriehoekY":[0-9]{6}.[0-9]{3}
Any ideas how to solve this issue?

Thanks @hkingsbury ! The regex works perfect. I have filtered now all records which contain coordinate values.
However, I still need to subtract these coordinates from the string per record and turn them into attribute values in such a way they can be used in a VertexCreator. Do you have any suggestions? 😃
My goal, using the example above, get finally 2 columns with x and y coordinates.
A small change to the regex can achieve that, adding two extra capture groups around the coords
adding a capture group around the whole statement "(...)"
switch [0-9] to \d
escaped '.'. In regex a '.' means any character. by escaping it with a '\' you will only match a '.'
to extract that match, use a StringSearcher. It there is a match it will come out on the '_first_match' attribute
One thing I did note, are your coordinates always going to be 6 long followed by 3dp? you may want to look at adding a range, especaily for the decimal places. {1,3} will match 1 to 3 numbers long
