Writing an XSLT Stylesheet Header

I'm building a C# application that will build me XSLT files based on a pre-configured file.

I can generate the XSLT file, and its close to what I want, but I'm having a couple issues.

Issue 1:
The stylesheet header at the top of the XSLT file is formatting weird. Here is what I'm expecting:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="1.0" xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40">

This is what I'm getting:

<xsl:stylesheet p1:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="1.0" xmlns="urn:schemas-microsoft-com:office:spreadsheet" p3:o="urn:schemas-microsoft-com:office:office"
p3:x="urn:schemas-microsoft-com:office:excel" p3:ss="urn:schemas-microsoft-com:office:spreadsheet" p3:html="http://www.w3.org/TR/REC-html40" xmlns:p3="xmlns" xmlns:p1="stylesheet"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

And here is the C# Code:

//Write the namespaces for the xslt
        xmlWriter.WriteStartElement("xsl", "stylesheet", "http://www.w3.org/1999/XSL/Transform");
        xmlWriter.WriteAttributeString("xs", "stylesheet", "http://www.w3.org/2001/XMLSchema");
        xmlWriter.WriteAttributeString("exclude-result-prefixes", "xs");
        xmlWriter.WriteAttributeString("version", "1.0");
        xmlWriter.WriteAttributeString("xmlns", "urn:schemas-microsoft-com:office:spreadsheet");
        xmlWriter.WriteAttributeString("o", "xmlns", "urn:schemas-microsoft-com:office:office");
        xmlWriter.WriteAttributeString("x", "xmlns", "urn:schemas-microsoft-com:office:excel");
        xmlWriter.WriteAttributeString("ss", "xmlns", "urn:schemas-microsoft-com:office:spreadsheet");
        xmlWriter.WriteAttributeString("html", "xmlns", "http://www.w3.org/TR/REC-html40");

Issue 2:
In the general body of my XSLT file, there are multiple locations where these "p" declarations seems to be showing up. In my output above, an example is:

p3:x="urn:schemas-microsoft-com:office:excel"

I think I'm miscalling the method in some way, but I'm not sure how to correct this.

It seems the arguments need to alter the position and be used in proper way.

ref: https://docs.microsoft.com/en-us/dotnet/api/system.xml.xmlwriter.writeattributestring?view=netframework-4.7.2

In your case, It should be written as

For Example :

xmlWriter.WriteAttributeString("xmlns", "ss", null, "urn:schemas-microsoft-com:office:spreadsheet");

Because WriteAttributeString(String, String, String, String)

When overridden in a derived class, writes out the attribute with the specified prefix, local name, namespace URI, and value.

public void WriteAttributeString (string prefix, string localName, string ns, string value);
