How can I parse the SVWZ in a way to only have the text (Verwendungszweck) extracted?

[simonschaufi]

Currently i get back:

ÜBERTRAG / ÜBERWEISUNG2026-10END-TO-END-REF.:NICHT ANGEGEBENRef. XXXXXXX/1111

I'm only interested in the Verwendungszweck. Is there any standard to extract that section from the SVWZ?
