Confusing looks, that you have some scritp and some script in your sample & demo. Is this meant? However you can use a negative lookahead if this would be convenient for your input:

  • ((?!</script).)*? matches lazily any amount of characters not followed by </script
  • until site and (?1) reuses the pattern in first group until </script> greedily.

For this kind of problems usually a parser solution is be to be preferred. Depends on input.
