Advanced use of DocumentBuilder

Return to the
DocumentBuilder
Developer CenterThe default approach to working with DocumentBuilder 2.0 enables you to take bits and pieces of multiple documents and assemble them together into a new document. However, there is an interesting scenario that this approach does not handle. You may want to import a document into a cell in a table, into a text box, or into a content control. You can do this with DocumentBuilder 2.0. The following video shows how:

This was the content that I presented in a web-cast on DocumentBuilder 2.0.

Here is the code I presented

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Xml.Linq;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Validation;
using OpenXmlPowerTools;

class Program
{
    static void Main(string[] args)
    {
        WmlDocument doc1 = new WmlDocument(@"..\..\Template.docx");
        using (MemoryStream mem = new MemoryStream())
        {
            mem.Write(doc1.DocumentByteArray, 0,
                doc1.DocumentByteArray.Length);
            using (WordprocessingDocument doc =
                WordprocessingDocument.Open(mem, true))
            {
                XDocument xDoc = doc
                    .MainDocumentPart
                    .GetXDocument();
                XElement frontMatterPara = xDoc
                    .Root
                    .Descendants(W.txbxContent)
                    .Elements(W.p)
                    .FirstOrDefault();
                frontMatterPara.ReplaceWith(
                    new XElement(PtOpenXml.Insert,
                        new XAttribute("Id", "Front")));
                XElement tbl = xDoc
                    .Root
                    .Element(W.body)
                    .Elements(W.tbl)
                    .FirstOrDefault();
                XElement firstCell = tbl
                    .Descendants(W.tr)
                    .First()
                    .Descendants(W.p)
                    .First();
                firstCell.ReplaceWith(
                    new XElement(PtOpenXml.Insert,
                        new XAttribute("Id", "Liz")));
                XElement secondCell = tbl
                    .Descendants(W.tr)
                    .Skip(1)

                    .Descendants(W.p)
                    .First();
                secondCell.ReplaceWith(
                    new XElement(PtOpenXml.Insert,
                        new XAttribute("Id", "Eric")));
                doc.MainDocumentPart.PutXDocument();
            }
            doc1.DocumentByteArray = mem.ToArray();
        }

        string outFileName = "Out.docx";
        File.Delete(outFileName);
        List sources = new List()
            {
                new Source(doc1, true),
                new Source(new WmlDocument(@"..\..\Insert-01.docx"), "Liz"),
                new Source(new WmlDocument(@"..\..\Insert-02.docx"), "Eric"),
                new Source(new WmlDocument(@"..\..\FrontMatter.docx"), "Front"),
            };
        DocumentBuilder.BuildDocument(sources, outFileName);
    }
