Is there a SAX way to loop through OpenXML rows?

I'm parsing a large file using the SAX approach offered on: Parsing and Reading Large Excel Files with the Open XML SDK

This is my modified version (only getting the row number for simplicity)

using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open("BigFile.xlsx", true))
{
    WorkbookPart workbookPart = myDoc.WorkbookPart;
    WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();

    OpenXmlReader reader = Open开发者_Go百科XmlReader.Create(worksheetPart);
    String rowNum;
    while (reader.Read())
    {
        if (reader.ElementType == typeof(Row))
        {
            if (reader.HasAttributes)
                rowNum = reader.Attributes.First(a => a.LocalName == "r").Value
        }
    }
}

The problem is that this loops through every item/cell/column/whatnot and only acts when the element type is Row.

Is there a SAX way to loop only through the rows and not every item in the worksheet?

Thanks,

The key is to use the Skip() and ReadNextSibling() methods of the reader...

 using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open("BigFile.xlsx", true))
 {
     WorkbookPart workbookPart = myDoc.WorkbookPart;
     WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
     OpenXmlReader reader = OpenXmlReader.Create(worksheetPart);
     String rowNum;
     while (reader.Read())
     {
         if (reader.ElementType == typeof(Row))
         {
             do
             {
                 if (reader.HasAttributes)
                     rowNum = reader.Attributes.First(a => a.LocalName == "r").Value;

             } while (reader.ReadNextSibling()); // Skip to the next row
             break; // We just looped through all the rows so no need to continue reading the worksheet
         }

         if (reader.ElementType != typeof(Worksheet)) // Dont' want to skip the contents of the worksheet
             reader.Skip(); // Skip contents of any node before finding the first row.
     }
}
