I have some XML files from another system and I want to be able to process the data therein. The readstruct function mostly fits the bill, but all the date/time fields get filled with "NaT" values because the input format isn't what datetime() expects and the Locale options aren't good enough. In particular, the input fomat is 'HH:mm:ss MM/dd/yyyy' which is I guess backwards from what datetime wants. The best option would be to add a "DateInputFormat" keyword to readstruct() that got passed as "InputFormat" to datetime(). Any other options?

Thanks for reporting this.

There is an undocumented " DetectTypes " parameter on readstruct . Enabling this will read all XML nodes as either string s or missing values. This might help work around the issue for you.

       
         >> type ans.xml
        
         <A>
        
         <B>11:12:13 10/15/2022</B>
        
         </A>
        
         >> S = readstruct(
        
         "ans.xml"
        
         , DetectTypes=false)
        
         S =
        
         struct
        
         with fields:
        
         B:
        
         "11:12:13 10/15/2022"

Please note that this is an undocumented parameter, and may change in a future release.
