Aspose.words: How to add a Node object in another Word document

Original: Aspose.words: How to add a Node object in another Word document

First look at a piece of code that is intended to fetch the first table from Docsource and insert the end of the Doctarget:

1 var 0 true ); 2 docTarget.FirstSection.Body.ChildNodes.Add (table);

This code throws an exception: "The NewChild is created from a different document than the one, and the created this node."

The reason is that For a Aspose.words node object, its control over a series of styles and formatting, depending on the Documentbase parent object it is in, which is also a lot of aspose.words object declarations, you must specify its documentbase parameters, such as declaring a table, as follows:

1 document doc=new  document (); 2 table table=new table (DOC);

So, do we have a way to add objects from another document? There, you must either pass the Document.importnode method or use the Nodeimporter object.

Both of these approaches are to import node from the source document into the target document, and then append node to the appropriate location.

A     foreach(Section SrcsectioninchSrcdoc) -     { -         //Because We are copying a sections from one document to another, the         //It's required to import the sections node into the destination document. -         //This adjusts any document-specific references to styles, lists, etc. -         // -         //Importing a node creates a copy of the original node, but the copy +         //is ready to be inserted into the destination document. -Node dstsection = Dstdoc.importnode (Srcsection,true, mode); +  A         //Now, the new section node can is appended to the destination document. at Dstdoc.appendchild (dstsection); -     } -}
