Formatierungen von JTextPane in xml umwandeln

Hi Leutz.

Ich habe ein ziemliches Problem und weiss nicht genau wie ich da ran gehen soll.

Ich muss mittels JasperReports einen Bericht erstellen und in diesem Bericht soll als Kommentar ein Formatierter Text eingefügt werden(es können in dem Text verschiedene Formatierungen vorhanden sein.. fett, kursiv, verschiedene Schriftarten- und -grössen.

wenn ich den Text in xml tags packe geht das auch. z.B. so..

<style isItalic="true" pdfFontName="Helvetica-Oblique">kursiv</style>
<style isBold="true" pdfFontName="Helvetica-Bold">fett</style>
usw.

geht das auch irgendwie anderst Also ich habe bei JasperReports keine andere möglichkeit gefunden.. aber vielleicht weiss ja jemand ne andere lösung.

Ich hätte ein JTextPane genommen, die Formatierung ausgelesen, den text mit den entsprechenden xml tags versehen und in der Datenbank/Textdatei als xml-Text gespeichert.

Hier mal mein Ansatz.. (noch ne Frage zum Code.. muss ich da jetzt ne schleife machen und JEDE Schriftgrösse bzw. Schriftart abfragen!)
