Text suchen und ersetzen im Word Dokument

[imox]

Hey Leute,

ich bin auf der Suche nach einer Lösung wie ich in einem Word Dokument "Variablen" suchen und ersetzen kann. Mein Ansatz ist, dass die Variablen immer in "#{}" verpackt werden müssen. Als API nehme ich Apache POI (XWPFDocument usw.).

Der Aufbau sieht ja dann wie folgt aus. XPWFDocument hat ne Liste von XWPFParagraphen die haben dann noch mal eine Liste mit XWPFRuns in dem dann der Text und die jeweilige Formatierung steht.

Dass knifflige ist jetzt, dass jeglicher Text auf verschiedene Paragraphen und Runs aufgesplittet sein kann. Hier mal mein Code was ich bisher gemacht hatte. Klappt auch einigermaßen doch allerdings gibt es immer wieder Fälle wo es nicht mehr hinhaut. Ich glaube ich mach das auch alles viel zu kompliziert, mir fällt aber leider irgendwie keine andere Lösung ein.

Ich hoffe jemand von euch hat den Elan sich meinen code anzuschauen 😉 dafür dann schon mal vielen vielen Dank bzw. wenn jemand eine komplett andere Lösung hat wäre super.

Hey Leute,

also ich hab mich gestern noch mal den ganzen Tag ran gesetzt und bin das ganze komplett anders angegangen und hab jetzt ne super Lösung die um einiges strukturierter ist und funktioniert 😉. Ich kann mir auch gut vorstellen, dass das den ein oder anderen auch helfen könnte. Ich stelle hier einfach mal mein ganzes XWPFUtil rein.
