aspose.Words：如何添加另一個WORD文檔中的Node對象

首先看一段代碼，這段代碼意圖從docSource中獲取第一個表格，并插入docTarget的末尾：

1 var table = (Table)docSource.GetChild(NodeType.Table, 0, true);2 docTarget.FirstSection.Body.ChildNodes.Add(table);

這段代碼會拋出異常：“The newChild was created from a different document than the one that created this node.”，這是什么原因呢？

原因是，對于Aspose.Words的Node對象，它的一系列樣式和格式的控制，取決于它所在的DocumentBase父對象，這也是很多Aspose.Words對象聲明時，必須指定它的DocumentBase參數，比如聲明一個Table，應該如下：

1 Document doc=new Document();2 Table table=new Table(doc);

那么，我們有沒有辦法添加另一個文檔中的對象呢？有，必須通過Document.ImportNode方法或者使用NodeImporter對象。

這兩種方法思路都是將源文檔中的Node導入到目標文檔中，再追加Node到合適的位置。

 1 /// <summary> 2 /// A manual implementation of the Document.AppendDocument function which shows the general  3 /// steps of how a document is appended to another. 4 /// </summary> 5 /// <param name="dstDoc">The destination document where to append to.</param> 6 /// <param name="srcDoc">The source document.</param> 7 /// <param name="mode">The import mode to use when importing content from another document.</param> 8 public void AppendDocument(Document dstDoc, Document srcDoc, ImportFormatMode mode) 9 {10     // Loop through all sections in the source document. 11     // Section nodes are immediate children of the Document node so we can just enumerate the Document.12     foreach (Section srcSection in srcDoc)13     {14         // Because we are copying a section from one document to another, 15         // it is required to import the Section node into the destination document.16         // This adjusts any document-specific references to styles, lists, etc.17         //18         // Importing a node creates a copy of the original node, but the copy19         // is ready to be inserted into the destination document.20         Node dstSection = dstDoc.ImportNode(srcSection, true, mode);21 22         // Now the new section node can be appended to the destination document.23         dstDoc.AppendChild(dstSection);24     }25 }

 1 public static Document GenerateDocument(Document srcDoc, ArrayList nodes) 2         { 3             // Create a blank document. 4             Document dstDoc = new Document(); 5             // Remove the first paragraph from the empty document. 6             dstDoc.FirstSection.Body.RemoveAllChildren(); 7  8             // Import each node from the list into the new document. Keep the original formatting of the node. 9             NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting);10 11             foreach (Node node in nodes)12             {13                 Node importNode = importer.ImportNode(node, true);14                 dstDoc.FirstSection.Body.AppendChild(importNode);15             }16 17             // Return the generated document.18             return dstDoc;19         }
