Converting XML files to Libreoffice Calc

[Max Pyziur]

Greetings,

A data site provides downloadable data in xml format; the header reads:
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" 
xmlns:o="urn:schemas-microsoft-com:office:office" 
xmlns:x="urn:schemas-microsoft-com:office:excel" 
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" 
xmlns:html="http://www.w3.org/TR/REC-html40">
<DocumentProperties xmlns="urn:schemas-microsoft-com:office:office">
<Created>2016-12-01T15:08:55Z</Created>
<Version>1</Version>
</DocumentProperties>
<ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel"/>
<Styles>


It imports seamlessly into MS Excel. I'm flummoxed as to how to do the 
same in Libreoffice. I've searched for LibreOffice XML filters, but I 
haven't come across anything yet.

Much thanks for any guidence.
