UTL_FILE Read .TXT file and Append with HTML Tables

Hi All,

I need to fetch a set of texts from the file (abc.txt) based on shared directory (i.e. editable by user).

Also HTML Table Cursor values should be  fetched (which i am performing via HTML tag with in Procedure).

I need the text to be fetched starting from certain position. e.g. all the blue highlighted image(attached below) can be dynamically changed i.e. kept in text file.

After first table is printed then Customer New Details: - Static value should be fetched and Table-2 image should be printed.

l_line - Printed all the values in the text file correctly. But using REGEXP_SUBSTR how can i fetch only the particular text string print it along with HTML tables ..  then use other set of String print it?
