PowerTools for Xml Corrupts Document when using NormalizeXML

Question

I am normalizing my docx document using the NormalizeXml function from the XML Powertools 2.2 with this code:

SimplifyMarkupSettings settings = new SimplifyMarkupSettings{
           NormalizeXml = true,
};

My goal is to search and replace variables, but the variables are not always in the same "Run Property" and as a result does not get replaced. I also do not want to disable the proofing in Office.

After running my program the docx file is corrupt and complains about styles when I try to open it (and the NormalizeXml function did not work or finish):

The XML Data is invalid according to the schema. Part:/word/styles.xml,Line 1, Column 0

I am using OpenXml 2.0 since OpenXml 2.5 needs .Net 4.5

I'm also using Office 2013.

When I use the OpenXml 2.0 Productivity Tool it picks up the error like this:

Error Node Type : Styles Error Part : /word/styles/xml Error Node Path : /w:styles1 Description : The Ignorable attribute is invalid - The value 'w14 w15' contains an invalid prefix that is not defined.

Here is what I see when I open styles.xml :

<?xml version="1.0" encoding="utf-8"?><w:styles mc:Ignorable="w14 w15" xmlns:wpc="http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:wp14="http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" xmlns:w14="http://schemas.microsoft.com/office/word/2010/wordml" xmlns:wpg="http://schemas.microsoft.com/office/word/2010/wordprocessingGroup" xmlns:wpi="http://schemas.microsoft.com/office/word/2010/wordprocessingInk" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml" xmlns:wps="http://schemas.microsoft.com/office/word/2010/wordprocessingShape">

I would like to keep the documents compatible between Office 2007/2010/2013.

At this stage I am considering searching for this "mc:Ignorable="w14 w15" attribute and doing an empty replace but there must be a better way to do this.

Thanks for any advice.

Did you ever figure this out? – wensveen Oct 27 '21 at 12:45 — wensveen, Oct 27 '21 at 12:45

My temporary solution is to make sure the variables (and any characters used to detect the variable for example : #name#) in the document that needs to be replaced are of EXACTLY the same font so the "Run Properties" don't get broken up.

I am also using EditIx to make sure the variable is in ONE "Run Property", but this is not ideal as I want the users to add their own variables later.

Check this post Programmatically save OpenXml document as previous version (Word 2007)

You'll have to modify your open xml power tools code.

This worked for me.

Hope this helps.

Apparently, superfluous namespace declarations in the root element are removed with NormalizeXml = true but the associated prefixes that are mentioned in the mc:Ignorable attribute are not.

I use this to recursively inspect and fix all OpenXmlParts in the document:

private static void FixIgnorableAttributes(OpenXmlPartContainer container)
{
    container.Parts.Select(idPartPair => idPartPair.OpenXmlPart).ToList().ForEach(part =>
    {
        var ignorableAttribute = part.RootElement?.MCAttributes?.Ignorable;
        if (ignorableAttribute != null && ignorableAttribute.HasValue)
        {
            var root = part.GetXDocument().Root;

            ignorableAttribute.Value =
                string.Join(" ", ignorableAttribute.Value.Split(" ", StringSplitOptions.RemoveEmptyEntries).
                    Where(prefix => root.GetNamespaceOfPrefix(prefix) != null));
        }

        // Recursively fix descendant parts
        FixIgnorableAttributes(container: part);
    });
}

Usage:

using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(pathOrStream, true))
{
    MarkupSimplifier.SimplifyMarkup(wordDocument, new SimplifyMarkupSettings { NormalizeXml = true });

    // Fix ignorables attributes
    FixIgnorableAttributes(wordDocument);
}
