Summary: DateUtil.isADateFormat Replaces Characters Incorrectly
Product: POI
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: HSSF
AssignedTo: [email protected]
ReportedBy: [email protected]
I have an Excel 2003 spreadsheet in which a cell has the custom date format:
yyyy\-mm\-dd\Thh:mm:ss
DateUtil.isaDateFormat trashes this by converting the '\T' to '.' The problem
is this line of code:
// And \. into .
fs = fs.replaceAll("\\\\.",".");
It should be:
fs = fs.replaceAll("\\\\\\.",".");
The regex parser sees the former as '\\.' which it interprets as backslash
followed by any character. The regex parser sees the latter as '\\\.' which it
reads as backslash followed by period -- which is what the code wanted to do.
