ich eine HTML-Seite ansprechbar für eine mobile App zu schaffen, basierend auf folgende XML-Struktur:

<?xml version="1.0" encoding="UTF-8"?>

He then applied for a vendor license to bid on contracts for the State of Texas, winning bids by not having the overhead of a computer store</explanation>

Grundsätzlich jedes Absatz Element wird eine neue Linie von Absatz erstellen. Und jedes Element innerhalb des Absatzes definiert das Textformat.

Absatz/Text definiert die Kopfzeile des Absatzes. Es sollte eine weitere Absatz/Erklärung Element folgen. Einige Erklärung möglicherweise in mehrere Absätze unterteilt.

Ich bin mir nicht sicher, wie man Parser schreibt, um diese Datei zu lesen.

z. Ausgabe

PS: Ich kann auf die Formatierung achten. Brauchen nur Ideen, um das Dokument effizient zu parsen. Da jedes XML etwa 2-3 MB sein kann.
