Examples

The following code example shows how to access elements at the same level in a word-processing document. The test file used in the example contains the text “OpenXml Element.”

using System;  
using System.Collections.Generic;  
using System.Linq;  
using DocumentFormat.OpenXml.Packaging;  
using DocumentFormat.OpenXml.Wordprocessing;  
  
namespace OpenXmlElement  
{  
    class Program  
    {  
        // This code example shows how to access elements at the same level    
        // in a word-processing document.   
        // The example is using a file that contains the text "OpenXml Element."  
        static void Main(string[] args)  
        {  
            string fileName = @"C:\Users\Public\Documents\AccessElementsSameLevel.docx";  
            using (WordprocessingDocument wordprocessingDocument =   
                WordprocessingDocument.Open(fileName, false))  
            {  
                // Create a Body object.  
                DocumentFormat.OpenXml.Wordprocessing.Body body =  
                    wordprocessingDocument.MainDocumentPart.Document.Body;  
  
                // Create a Paragraph object.  
                DocumentFormat.OpenXml.Wordprocessing.Paragraph firstParagraph =  
                    body.Elements<Paragraph>().FirstOrDefault();  
  
                // Get the first child of an OpenXmlElement.  
                 DocumentFormat.OpenXml.OpenXmlElement firstChild = firstParagraph.FirstChild;  
                IEnumerable<Run> elementsAfter =  
                    firstChild.ElementsAfter().Where(c => c is Run).Cast<Run>();  
  
                // Get the Run elements after the specified element.  
                Console.WriteLine("Run elements after the first child are: ");  
                foreach (DocumentFormat.OpenXml.Wordprocessing.Run run in elementsAfter)  
                {  
                    Console.WriteLine(run.InnerText);  
                }  
                Console.ReadKey();  
            }  
        }  
    }  
}  
// Output:  
// Run elements after the first child are:  
// OpenXml  
//  Element
