OpenXML is a new standard used by all of Microsoft's new Office suites (Office 2007)! Because it is an open standard and based on XML, we can easily parse documents created with these products. The topic of this article will be how to parse a Word document (using XLINQ) and then render the document in a WPF control called the
Parsing an OpenXML Document using XLINQ
The first problem is to extract or unpack the *.docx file into its containing *.xml files.
Package package = Package.Open(filename);
Uri documentUri = new Uri("/word/document.xml", UriKind.Relative);
PackagePart documentPart = package.GetPart(documentUri);
XElement wordDoc = XElement.Load(new StreamReader(documentPart.GetStream()));
The snippet above opens a Word document, extracts the document.xml into an
Using XLINQ to Get All the Paragraphs
All Word documents require the
XNamespace w = http:;
Now we can make a simple XLINQ query to get all the paragraphs (please note: to keep this simple, I am only looking at the
paragraphs, I ignore images, drawings, tables, etc.).
var paragraphs = from p in wordDoc.Descendants(w + "p")
Next, we iterate over the collection of
paragraphs and display them in a
Sacha has a nice article on the basics of
FlowDocuments available here!
foreach (var p in paragraphs)
var style = from s in p.Descendants(w + "pPr")
var font = (from f in style.Descendants(w + "rFonts")
var size = (from s in style.Descendants(w + "sz")
Paragraph par = new Paragraph();
Run r = new Run(p.Value);
if (font != null)
FontFamilyConverter converter = new FontFamilyConverter();
r.FontFamily = (FontFamily)converter.ConvertFrom(font.Value);
if (size != null)
r.FontSize = double.Parse(size.Value);
paragraph, I check if it has a
font family or
size explicitly set. I then create a new
Paragraph and add a
Run to its
Inlines collection (I also change the
font family and
size if available). I then add the
Paragraph to my
And that is it!
All that is left now is to find a cool way to extend the normal
FlowDocument to support Word document? You can sub-class the
FlowDocument... I decided to rather provide it as an extension method!
To load a Word document into a flow document, you first create a
FlowDocumentViewer (I created it in XAML):
<FlowDocumentPageViewer x:Name="flowDocViewer" Zoom="80" />
And load the Word document...
FlowDocument flowDoc = new FlowDocument();
flowDocViewer.Document = flowDoc;
I created a simple Word document with all the WPF Disciples bios. Here is how it looks in a
Simple and easy...
