Can I read rich text in one cell?

[sgqy]

Rich text example: https://xlsxwriter.readthedocs.io/example_rich_strings.html For example in sharedStrings.xml. The mixed style shows like:

<si>
  <r>
    <t>The color called </t>
  </r>
  <r>
    <rPr>
      <color rgb="FFFF0000"/>
    </rPr>
    <t>red</t>
  </r>
</si>

Can I get the raw si element or other equipment format which includes embedded rich text? Thanks. :)
