Solution – XML Parsing Error in Microsoft Word File (Corrupted File)
If you are using Word 2007, 2010, or 2013, you may encounter a strange error when trying to open a DOCX file. Recently, I tried to open a DOCX file that I had created on Windows 10 using Office 2013 and got the following error:
The name in the element's end tag must match the element type in the opening tag.
Hmm, no idea what that means! After some research I found out that this error has to do with the XML code that makes up a DOCX file. Normally this error does not lead to the loss of your file or its contents, but it is a good idea to make a copy of the file before making any changes.
