The WPF DocumentViewer Control

[usolo]

I made a xps reader with the DocumentViewer control.How can I reader the xps file with DocumentStructView just like the doc file in Office Word open.- -!Sorry,my English is poor!Thanks.

public int ListInXpsDoc(string srcXpsDocument)
{
int numImages = 0;
int numPages = 0;
XpsDocument document = new XpsDocument(srcXpsDocument, FileAccess.Read);
IXpsFixedDocumentSequenceReader docSequence = document.FixedDocumentSequenceReader;
if (docSequence != null)
{

            foreach (IXpsFixedDocumentReader docSeqDocument in docSequence.FixedDocuments)
            { 
                foreach (IXpsFixedPageReader docPage in docSeqDocument.FixedPages)
                { 
                    numPages++; 
                }
            } 
        }
        document.Close();
        return numPages; 
    }
