What indicates an Office Open XML Cell contains a Date/Time value?
The s attribute references a style xf entry in styles.xml. The style xf in turn references a number format mask.

OpenXML SDK returning a number for CellValue instead of cells text
All strings in an Excel worksheet are stored in a array like structure called the SharedStringTable.

How to access OpenXML content by page number?
You cannot reference OOXML content via page numbering at the OOXML data level alone. Hard page breaks are not the problem; hard page breaks can be counted. Soft page breaks are the problem.

OpenXML tag search
The problem with trying to find tags is that words are not always in the underlying XML in the format that they appear to be in Word. For example, in your sample XML the <!TAG1!> tag is split across multiple runs like this: <w:r> <w:rPr> <w:lang w:val=”en-GB”/> </w:rPr> <w:t><!TAG1</w:t> </w:r> <w:proofErr w:type=”gramEnd”/> <w:r> <w:rPr> <w:lang … Read more
Export big amount of data from XLSX – OutOfMemoryException
