例子

展示如何创建/删除结构化文档标签及其内容。

public void SdtRangeExtendedMethods()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    builder.Writeln("StructuredDocumentTag element");

    InsertStructuredDocumentTagRanges(doc, out StructuredDocumentTagRangeStart rangeStart);

    // 删除范围结构化文档标签，但保留内部内容。
    rangeStart.RemoveSelfOnly();

    rangeStart = (StructuredDocumentTagRangeStart)doc.GetChild(
        NodeType.StructuredDocumentTagRangeStart, 0, false);
    Assert.AreEqual(null, rangeStart);

    StructuredDocumentTagRangeEnd rangeEnd = (StructuredDocumentTagRangeEnd)doc.GetChild(
        NodeType.StructuredDocumentTagRangeEnd, 0, false);

    Assert.AreEqual(null, rangeEnd);
    Assert.AreEqual("StructuredDocumentTag element", doc.GetText().Trim());

    InsertStructuredDocumentTagRanges(doc, out rangeStart);

    Node paragraphNode = rangeStart.LastOrDefault();
    Assert.AreEqual("StructuredDocumentTag element", paragraphNode?.GetText().Trim());

    // 删除范围内的结构化文档标签和内容。
    rangeStart.RemoveAllChildren();

    paragraphNode = rangeStart.LastOrDefault();
    Assert.AreEqual(null, paragraphNode?.GetText());
}

public void InsertStructuredDocumentTagRanges(Document doc, out StructuredDocumentTagRangeStart rangeStart)
{
    rangeStart = new StructuredDocumentTagRangeStart(doc, SdtType.PlainText);
    StructuredDocumentTagRangeEnd rangeEnd = new StructuredDocumentTagRangeEnd(doc, rangeStart.Id);

    doc.FirstSection.Body.InsertBefore(rangeStart, doc.FirstSection.Body.FirstParagraph);
    doc.LastSection.Body.InsertAfter(rangeEnd, doc.FirstSection.Body.FirstParagraph);
}
