Excel cannot import all XML Cells

Hello! I have imported a XML file through the developer tools but I can't import all the cells.

For example, if I want to import the text from the cell 4.3. ...

... I can't find it in the XML-Source.

It looks like I can't import the text of a cell, if it has other child cells under (e.g. I can import I-4.3.1. but not I-4.3)

Is there anyway to solve this problem?

Thank you in advance!
