导入和导出书签

从 XML 导入书签到现有 PDF 文件

ImportBookmarksWithXml 方法允许您从 XML 文件将书签导入 PDF 文件。为了导入书签，您需要创建 PdfBookmarkEditor 对象并使用 BindPdf 方法绑定 PDF 文件。之后，您需要调用 ImportBookmarksWithXml 方法。最后，使用 Save 方法保存更新后的 PDF 文件。以下代码片段向您展示如何从 XML 文件导入书签。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.Pdf-for-.NET
private static void ImportBookmarksFromXML()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Bookmarks();

    // Create an instance of PdfBookmarkEditor
    using (var bookmarkEditor = new Aspose.Pdf.Facades.PdfBookmarkEditor())
    {
        // Bind PDF document
        bookmarkEditor.BindPdf(dataDir + "ImportFromXML.pdf");

        // Import bookmarks
        bookmarkEditor.ImportBookmarksWithXML(dataDir + "bookmarks.xml");

        // Save PDF document
        bookmarkEditor.Save(dataDir + "ImportFromXML_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.Pdf-for-.NET
private static void ImportBookmarksFromXML()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Bookmarks();

    // Create an instance of PdfBookmarkEditor
    using var bookmarkEditor = new Aspose.Pdf.Facades.PdfBookmarkEditor();

    // Bind PDF document
    bookmarkEditor.BindPdf(dataDir + "ImportFromXML.pdf");

    // Import bookmarks
    bookmarkEditor.ImportBookmarksWithXML(dataDir + "bookmarks.xml");

    // Save PDF document
    bookmarkEditor.Save(dataDir + "ImportFromXML_out.pdf");
}

从现有 PDF 文件导出书签到 XML

ExportBookmarksToXml 方法允许您将书签从 PDF 文件导出到 XML 文件。

导出书签的步骤：

1. 创建一个 PdfBookmarkEditor 对象，并使用 BindPdf 方法绑定 PDF 文件。
2. 调用 ExportBookmarksToXml 方法。
3. 使用 Save 方法保存更新后的 PDF 文件。

以下代码片段向您展示如何将书签导出到 XML 文件。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.Pdf-for-.NET
private static void ExportBookmarksToXML()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Bookmarks();

    // Create an instance of PdfBookmarkEditor
    using (var bookmarkEditor = new Aspose.Pdf.Facades.PdfBookmarkEditor())
    {
        // Bind PDF document
        bookmarkEditor.BindPdf(dataDir + "ExportToXML.pdf");

        // Export bookmarks to an XML file
        bookmarkEditor.ExportBookmarksToXML(dataDir + "bookmarks.xml");
    }
}

.NET 8

{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Bookmarks();

    // Create an instance of PdfBookmarkEditor
    using var bookmarkEditor = new Aspose.Pdf.Facades.PdfBookmarkEditor();

    // Bind PDF document
    bookmarkEditor.BindPdf(dataDir + "ExportToXML.pdf");

    // Export bookmarks to an XML file
    bookmarkEditor.ExportBookmarksToXML(dataDir + "bookmarks.xml");
