add and subtract values in xml string

Hey guys
A little programming question.  I have a fingerprint time clock that outputs to a xml file that is formatted for spreadsheets.  Problem is this.  If a person clocks in first thing in the morning and clocks out for lunch and then back in and back out at the end of the day, the Time clock puts all the time values inside one cell, or string (if you open it with Notepad).  Is there a way to take this data and calculate a total time at work for that one day?  Or am I stuck with manually calculating it up.

What does the string look like in notepad?

Is it like "09:00 12:01 13:01 17:15"

Does it store the date in a separate cell?

Are there incomplete records such as
"13:00 18:01 19:04"
where someone logged in but forgot to log out at the end of their shift or worked through until after midnight?

Can you post a sample of the Excel file? It should be possible to split the values, but need to see the data we're dealing with.

Hi, it is possible to split those values to get the individual time elements, but the sample has an odd mixture of duplicated entries and unpaired values. Is this because the system is not yet live?
TimesheetXML.pngI have to query this to establish how you want to deal with the following cases:
1. Unpaired values (perhaps login but not logout or vice versa). Should this produce a zero result?
2. Odd numbers of entries (as on 9th), which also imply an unpaired login or logout
3. Multiple instances of the same time value (as on 9th) - should all but the first instance be disregarded?

how you are seeing it is how it shows up on the big report.  Turns out there is a summary report that I didn't know about.  It summarized everyones time into a grand total of hours for each person.  So, I don't need to do any programming..   thank god :-)

His questions prompted me to dig deeper into the system and I found what I was looking for.  Therefore points should go to him :-0
