            Bug ID: 126515
           Summary: FILEOPEN: Cannot open XML (Excel) with style parent
                    ref.
           Product: LibreOffice
           Version: 6.3.0.2 rc
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal

Created attachment 152954
  --> https://bugs.documentfoundation.org/attachment.cgi?id=152954&action=edit
Original file from ark.intel.com

It is not possible to open an XML (Excel) file having a Style tag with Parent
attribute. The error message "General Error. General input/output Error." is
shown while opening the file in LibreOffice Calc.

My file was generated by ark.intel.com about processor information:
https://ark.intel.com/content/www/us/en/ark/products/75460/intel-core-i7-4500u-processor-4m-cache-up-to-3-00-ghz.html
I exported the file by clicking the "Export specifications" link.

After removing
<ss:Style ss:ID="s22link" ss:Parent="s22"><ss:Font ss:Color="Blue"
/></ss:Style>
I could open the file.

Steps to reproduce:
1. Open Intel_ARK_ComparisonChart_2019_07_23_original.xml in LO Calc
--> "General Error. General input/output Error."
2. Open Intel_ARK_ComparisonChart_2019_07_23_modified.xml where the offending
Style tag was removed
--> File is opened

Actual Result:
An error message is shown and the original file cannot be opened.

Expected result:
The original file opens without error in LO Calc.

Versions
I tested it on LO 6.2.5.2 Linux and LO 6.3.0.2 Windows.

File type of XML (Excel) file:
<?xml version="1.0"?><?mso-application progid="Excel.Sheet"?><ss:Workbook
xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">

I do not know if this Style tag having a Parent attribute is valid or not for
the above file type.
