How to: Validate the Contents of a Document Part in an Office Open XML Package by Using the Open XML API

This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

The Office Open XML Package specification defines a set of XML files that contain the content and define the relationships for all of the document parts stored in a single package. These packages combine the parts that comprise the document files for Microsoft® Office Excel® 2007, Microsoft Office PowerPoint® 2007, and Microsoft Office Word 2007. The Open XML Application Programming Interface (API) allows you to create packages and manipulate the files that comprise the packages. This topic walks through the code and steps to validate the contents of a document part in an Office Open XML package in Office Word 2007, although the steps are the same for each of the three 2007 Microsoft Office system programs that support the Office Open XML Format.

Validating the Contents of a Part in an Office Open XML Package

In the following code, you validate the XML content of the MainDocumentPart part of a WordprocessingDocument package by calling the ValidateXml method of MainDocumentPart part.

' How to validate the contents of a document part.
Public Sub ValidDocumentContent(ByVal document As String, ByVal schemaFile As String)
    Dim wordDoc As WordprocessingDocument = WordprocessingDocument.Open(document, false)
    wordDoc.MainDocumentPart.ValidateXml(schemaFile, Nothing)
End Sub
// How to validate the contents of a document part.
public static void ValidDocumentContent(string document, string schemaFile)
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, false))
    {
        wordDoc.MainDocumentPart.ValidateXml(schemaFile, null);
    }
 }

To validate the XML content of the MainDocumentPart part by calling the ValidateXml method of MainDocumentPart part

  1. First, pass in parameters representing the path to and the name of the source Word 2007 document as well as a schema file.

  2. Then, open the document as a WordprocessingDocument object.

  3. Next, create a reference to the MainDocumentPart part and call the ValidateXml method.

  4. Finally, the ValidateXml method uses the schema file to validate the XML contents of the MainDocumentPart part.

    NoteNote

    The Validate method does not validate the structure of an Office Open XML Package. For more information, see How to: Validate an Office Open XML Package by Using the Open XML API.
