目录（TOC）是Word文档的重要组成部分。它提供了文档内容的概述，并允许您快速导航到所需的部分。您可能会遇到需要以编程方式从Word文档中添加，提取，更新或删除目录的情况。为此，本文将教您如何使用C ++处理Word文件中的目录。

在Word文档中添加目录
以下是在Word文档中添加目录的步骤。
使用Document 类加载Word文件 。使用先前创建的Document对象创建DocumentBuilder类的实例 。使用DocumentBuilder-> InsertTableOfContents（System :: String开关）方法插入目录。使用Document-> UpdateFields（）方法填充目录。使用Document-> Save（System :: String fileName）方法保存Word文档。
下面的示例代码显示了如何使用C ++在Word文档中添加目录。
// Source and output directory paths.System::String sourceDataDir = u"SourceDirectory\\";System::String outputDataDir = u"OutputDirectory\\";// Load the Word fileSystem::SharedPtrdoc = System::MakeObject(sourceDataDir + u"Sample 5.docx");// Create an instance of the DocumentBuilder classSystem::SharedPtrbuilder = System::MakeObject(doc);// Insert a table of contents at the beginning of the document.builder->InsertTableOfContents(u"\\o \"1-3\" \\h \\z \\u");// The newly inserted table of contents will be initially empty.// It needs to be populated by updating the fields in the document.doc->UpdateFields();// Output file pathSystem::String outputPath = outputDataDir + u"AddTOC.docx";// Save the Word filedoc->Save(outputPath);
从Word文档中提取目录
以下是从Word文档中提取目录的步骤。
使用Document 类加载Word文件 。使用Document-> get_Range（）-> get_Fields（）方法检索字段并在它们上循环。检查字段是否为FieldType :: FieldHyperlink类型。检查该字段是否属于目录。检索并打印字段信息。
下面的示例代码演示了如何使用C ++从Word文档中提取目录。
// Source direvctorySystem::String inputDataDir = u"SourceDirectory\\";// Load the Word fileSystem::SharedPtrdoc = System::MakeObject(inputDataDir + u"SampleTOC.docx");// Loop through the fieldsfor (System::SharedPtrfield : System::IterateOver(doc->get_Range()->get_Fields())){// Get FieldHyperlink fieldsif (field->get_Type() == FieldType::FieldHyperlink){System::SharedPtrhyperlink = System::DynamicCast(field);// Check if field belongs to TOCif (hyperlink->get_SubAddress() != nullptr && hyperlink->get_SubAddress().StartsWith(u"_Toc")){System::SharedPtrtocItem = System::DynamicCast(field->get_FieldStart()->GetAncestor(NodeType::Paragraph));std::cout << System::StaticCast(tocItem)->ToString(SaveFormat::Text).Trim().ToUtf8String() << std::endl; std::cout << "------------------" << std::endl; if (tocItem != nullptr) { System::SharedPtrbm = doc->get_Range()->get_Bookmarks()->idx_get(hyperlink->get_SubAddress());// Get the location this TOC Item is pointing toSystem::SharedPtrpointer = System::DynamicCast(bm->get_BookmarkStart()->GetAncestor(NodeType::Paragraph));std::cout << System::StaticCast(pointer)->ToString(SaveFormat::Text).ToUtf8String() << std::endl; } } } }
更新Word文档中的目录
如果文档的内容已更新，并且您需要在目录中反映这些更改，则只需加载Word文件并调用 Document-> UpdateFields（） 方法。此方法将根据修改后的内容更新目录。之后，保存更新的Word文档。
以下是从Word文档中删除目录的步骤。
使用Document 类加载Word文件 。检索并存储FieldStart节点的列表。遍历节点，直到到达指定目录结尾的类型NodeType :: FieldEnd的节点。使用Node-> Remove（）方法删除目录。使用Document-> Save（System :: String fileName）方法保存Word文档。
下面的示例代码显示了如何使用C ++从Word文档中删除目录。
void RemoveTableOfContents(const System::SharedPtr& doc, int32_t index){// Store the FieldStart nodes of TOC fields in the document for quick access.std::vectorfieldStarts;// This is a list to store the nodes found inside the specified TOC. They will be removed// at the end of this method.std::vectornodeList;for (System::SharedPtrstart : System::IterateOver(doc->GetChildNodes(NodeType::FieldStart, true))){if (start->get_FieldType() == FieldType::FieldTOC){// Add all FieldStarts which are of type FieldTOC.fieldStarts.push_back(start);}}// Ensure that the TOC specified by the passed index exists.if (index > fieldStarts.size() - 1){throw System::ArgumentOutOfRangeException(u"TOC index is out of range");}bool isRemoving = true;// Get the FieldStart of the specified TOC.System::SharedPtrcurrentNode = fieldStarts[index];while (isRemoving){// It is safer to store these nodes and delete them all at once later.nodeList.push_back(currentNode);currentNode = currentNode->NextPreOrder(doc);// Once we encounter a FieldEnd node of type FieldTOC then we know we are at the end// of the current TOC and we can stop here.if (currentNode->get_NodeType() == NodeType::FieldEnd){System::SharedPtrfieldEnd = System::DynamicCast(currentNode);if (fieldEnd->get_FieldType() == FieldType::FieldTOC){isRemoving = false;}}}// Remove all nodes found in the specified TOC.for (System::SharedPtrnode : nodeList){node->Remove();}}int main(){// Source and output directory paths.System::String sourceDataDir = u"SourceDirectory\\";System::String outputDataDir = u"OutputDirectory\\";// Open a Word documentSystem::SharedPtrdoc = System::MakeObject(sourceDataDir + u"SampleTOC.docx");// Remove the first table of contents from the document.RemoveTableOfContents(doc, 0);// Output file pathSystem::String outputPath = outputDataDir + u"RemoveTOC.docx";// Save the Word filedoc->Save(outputPath);}
