XPathNavigator Operations, C#

[joe_pool_is]

I'm trying to pull some data from a Microsoft Word XML Document, but the code I have generates sloppy output (see streamLog.txt). I am trying to write each row of tab delimited data on its own line, but I never appends a carriage return.

 

My code consists of 2 methods: readDocument and getXmlTables. The readDocument routine works - it is just to show you how I open the file (if anyone needs it). The problem comes from getXmlTables not putting rows on separate lines:

 

private void readDocument()
{
  XmlDocument myXMLDocument = new XmlDocument("myDoc.xml");
  const string wordDocXml = "/word/document.xml";
  string pkgNs = myXMLDocument.DocumentElement.Attributes["xmlns:pkg"].Value;
  XPathNavigator nav = myXMLDocument.CreateNavigator();
  if ((nav.MoveToFollowing("part", pkgNs)) && (nav.MoveToAttribute("name", pkgNs)))
     while (nav.Value != wordDocXml)
        if (!(nav.MoveToParent()) || !(nav.MoveToFollowing("part", pkgNs)) || !(nav.MoveToAttribute("name", pkgNs)))
           throw new InvalidOperationException("Unexpected file format. Missing [pkg] namespace.");
  if (nav.Value == wordDocXml)
  {
     string path = @"C:\Temp";
     if (Directory.Exists(path))
     {
        FileInfo file = new FileInfo(Path.Combine(path, "streamLog.txt"));
        using (StreamWriter sw = new StreamWriter(file.FullName, false, Encoding.UTF8))
        {
           getXmlTables(nav, sw);
           sw.Close();
        }
     }
  }
}

void getXmlTables(XPathNavigator nav, StreamWriter stream)
{
  string wNs = "[url]http://schemas.openxmlformats.org/wordprocessingml/2006/main[/url]";
  while (nav.MoveToFollowing("tbl", wNs))
  {
     while (nav.MoveToFollowing("tr", wNs))
     {
        while (nav.MoveToFollowing("t", wNs))
        {
           stream.Write(string.Format("{0}\t", nav.Value));
        }
        stream.WriteLine();
     }
     stream.WriteLine();
  }
  stream.WriteLine();
}

 

Forgive this question that seems simple, but I can't find an answer.

 

The attached zip file contains an XML document exported by Microsoft Word that I am trying to parse along with the log that it creates.

 

I've looked at several examples on how to use XPathNavigator, but there does not seem to be detailed information that I can grasp the concepts of.

 

Is anyone on here good at using XPathNavigator? I'd really like some advice from someone that is good at using XPathNavigator.
