  • Embed fonts, images, and color profiles.
  • Control compression, security, and pagination.

5. Save to XamlFixed

  • Generate XAML Fixed documents for printing or WPF display.
  • Maintain precise layout of text, shapes, and images.
  • Interoperable with FlowDocument/FixedDocument.
  • Customize resource dictionaries and metadata.

6. Save to OpenXPS

  • Produce OpenXPS-compliant packages.
  • Support for digital signatures and relationships.
  • Optimize ZIP containers for streaming/distribution.
  • Adjust compression levels for performance.

7. Save to XamlFlow and XamlFlowPack

  • Export dynamic, flow-based documents for flexible layouts.
  • Manage pagination, columns, and reflowable text.
  • XamlFlowPack bundles multiple Flow documents in one archive.
  • Ideal for responsive UIs, previews, and digital publishing.
var doc = new Document();
var builder = new DocumentBuilder(doc);

var shape = builder.InsertChart(ChartType.Pie, 432, 252);
var chart = shape.Chart;
chart.Title.Text = "XML Processor Chart Example";

chart.Series.Clear();
chart.Series.Add("Series 1",
    new string[] { "Category 1", "Category 2", "Category 3" },
    new double[] { 2.7, 3.2, 0.8 });

doc.Save("ChartOutput.xps");

8. Bookmarks and Navigation

  • Insert, update, or delete bookmarks.
  • Navigate directly to bookmarks in large documents.
  • Set bookmark levels when saving to XPS/XAML.
var doc = new Document();
var builder = new DocumentBuilder(doc);

builder.StartBookmark("Bookmark1");
builder.Write("Generated by Aspose.Words XML File Processor");
builder.EndBookmark("Bookmark1");

var saveOptions = new XpsSaveOptions();
saveOptions.OutlineOptions.BookmarksOutlineLevels.Add("Bookmark1", 1);

doc.Save("BookmarkOutput.xps", saveOptions);

9. Additional Editing Features

  • Find and replace text.
  • Add or edit headings, tables, lists, and footnotes.
  • Manage comments and track changes.
  • Insert images, charts, and embedded objects.

Best Practices

  • Initialize license early to avoid evaluation mode.
  • Use streaming APIs for very large files.
  • Dispose of document instances to free resources.
  • Validate XML schemas before loading when strict compliance is needed.
  • Profile save options (fidelity vs. compression) to optimize output.
  • Batch process conversions for efficiency in enterprise workflows.

Troubleshooting Tips

  • Ensure XML input is well-formed and valid.
  • Handle conversion exceptions gracefully.
  • Verify font and resource availability for accurate rendering.
  • Test output in different XPS/XAML viewers for compatibility.
