导出为 XML

使用 FormExamples.exportXml(...) 将表单字段数据保存为 XML。

public static void exportXml(Path inputFile, Path outputFile) throws Exception {
    Form form = new Form();
    try (OutputStream outputStream = Files.newOutputStream(outputFile)) {
        form.bindPdf(inputFile.toString());
        form.exportXml(outputStream);
    } finally {
        form.close();
    }
}
