Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 22.10. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in Aspose.Words which may affect existing code. Any behavior introduced that could be seen as regression and modifies the existing behavior is especially important and is documented here.

Added new FindReplaceOptions.IgnoreStructuredDocumentTags property

Related issue: WORDSNET-24241

The following public property is added to FindReplaceOptions class:

/// <summary>
/// Gets or sets a boolean value indicating either to ignore content of <see cref="StructuredDocumentTag"/>.
/// The default value is <c>false</c>.
/// </summary>
/// <remarks>
/// <para>
/// When this option is set to <c>true</c>, the content of <see cref="StructuredDocumentTag"/>
/// will be treated as a simple text.
/// </para>
/// <para>
/// Otherwise, <see cref="StructuredDocumentTag"/> will be processed as standalone Story
/// and replacing pattern will be searched separately for each <see cref="StructuredDocumentTag"/>,
/// so that if pattern crosses a <see cref="StructuredDocumentTag"/>, then replacement will not
/// be performed for such pattern.
/// </para>
/// </remarks>
public bool IgnoreStructuredDocumentTags { get; set; }

Use Case: Explains how to ignore StructuredDocumentTags while finding and replacing text.

Document doc = new Document("input.docx");

// Set options to ignore StructuredDocumentTags.
FindReplaceOptions options = new FindReplaceOptions() { IgnoreStructuredDocumentTags = true };
doc.Range.Replace("searchText", "replacement", options);

HtmlSaveOptions.MetafileFormat now affects OLE objects and controls

Related issue: WORDSNET-23562.

OLE objects and controls (shapes whose type is ShapeType.OleObject or ShapeType.OleControl) usually contain a metafile as a fallback image. Saving of such shapes to HTML has been changed in the following way:

  • The option HtmlSaveOptions.MetafileFormat can be used to choose the format which images of the shapes are saved to.
  • The option HtmlSaveOptions.ExportShapesAsSvg no longer affects the shapes.

In other words, OLE objects and controls are now treated as metafile images when a document is converted to HTML.

Implemented ability to move DocumentBuilder cursor inside structured document tag

Related issue: WORDSNET-23920

Now it is possible to move cursor of DocumentBuilder inside a structured document tag. To do this, the following new members of the DocumentBuilder class have been added:

/// <summary>
/// Moves the cursor to a structured document tag in the current section.
/// </summary>
/// <remarks>
/// The navigation is performed inside the current story of the current section. That is, if you moved the
/// cursor to the primary header of the first section, then <paramref name="structuredDocumentTagIndex"/>
/// specified the index of the structured document tag inside that header of that section.
/// When <paramref name="structuredDocumentTagIndex"/> is greater than or equal to 0, it specifies an index
/// from the beginning of the section with 0 being the first structured document tag. When
/// <paramref name="structuredDocumentTagIndex"/> is less than 0, it specified an index from the end of the
/// section with -1 being the last structured document tag.
/// </remarks>
/// <param name="structuredDocumentTagIndex">The index of the structured document tag to move to.</param>
/// <param name="characterIndex">The index of the character inside the structured document tag.
/// A negative value allows you to specify a position from the end of the structured document tag. Use -1 to
/// move to the end of the structured document tag. If the structured document tag is at the block level, and
/// you want to move the cursor to the end of its last paragraph, specify -2.</param>
public void MoveToStructuredDocumentTag(int structuredDocumentTagIndex, int characterIndex);

/// <summary>
/// Moves the cursor to the structured document tag.
/// </summary>
/// <param name="structuredDocumentTag">The structured document tag to move to.</param>
/// <param name="characterIndex">The index of the character inside the structured document tag.
/// A negative value allows you to specify a position from the end of the structured document tag. Use -1 to
/// move to the end of the structured document tag. If the structured document tag is at the block level, and
/// you want to move the cursor to the end of its last paragraph, specify -2.</param>
public void MoveToStructuredDocumentTag(StructuredDocumentTag structuredDocumentTag, int characterIndex);

/// <summary>
/// Returns true if the cursor is at the end of a structured document tag.
/// </summary>
public bool IsAtEndOfStructuredDocumentTag { get; }

/// <summary>
/// Gets the structured document tag that is currently selected in this DocumentBuilder.
/// </summary>
public StructuredDocumentTag CurrentStructuredDocumentTag { get; }

Use Case: Moving cursor to end of inline-level structured document tag and getting currently selected structured document tag.

Document doc = new Document("input.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

// Move to the end of the second structured document tag.
builder.MoveToStructuredDocumentTag(1, -1);

builder.Write(" Text at end of structured document tag.");

// Get currently selected structured document tag.
builder.CurrentStructuredDocumentTag.Color = Color.Green;


Added new public method List.HasSameTemplate

Related issue: WORDSNET-24142

A new List.HasSameTemplate() public method has been added:

/// <summary>
/// Returns true if the current list and the given list are created from the same template.
/// </summary>
public bool HasSameTemplate(List other)

Use Case: Explains how to work with List.HasSameTemplate().

List list1 = document.Lists[0];
List list2 = document.Lists[1];
List list3 = document.Lists[2];

if (list1.HasSameTemplate(list2))
    Console.WriteLine("These lists have the same list template.");

if (!list2.HasSameTemplate(list3))
    Console.WriteLine("These lists have different list templates.");

Obsolete LoadOptions.FlatOpcXmlMappingOnly and SaveOptions.FlatOpcXmlMappingOnly options were removed

Related issue: WORDSNET-21455

These options caused unexpected side-effects and decided to be removed eventually. Instead, it was suggested to convert the mapped document to FlatOpc file format directly. This approach has no side-effect and provides better output.

SaveOptions.UpdateSdtContent default value changed and marked as obsolete.

Related issue: WORDSNET-24030

Default value of SaveOptions.UpdateSdtContent has been changed to False to follow MS Word behavoir, MS Word does not update content of common (not mapped) SDT from SDT values.

Also we decided to remove this option later as it causes unexpected side-effects similar to FlatOpcXmlMappingOnly load/save option.

Instead we going to provide new method which should be called explicitly to update SDT content according to the values.
