Shell Scripting help

i have a text file and having many lines and i need to fetch few details and paste it to another file in CSV format.

I am using this command to fetch the values.

Code:
grep 'pName="vin'  temp.txt | sed -n 's:.*<mis>\(.*\)</mis>.*<seg>\(.*\)</seg>.*:\1\,\2:p'

and getting output as this

Code:
11111111,Pit
333333,zit

but how can i get dateTime in ouput as well (as mentioned in below format).

For Ex:
temp.txt (file)
Code:
<l:ev dateTime="2019-06-14 08:30" pName="vin"> <mis>11111111</mis><seg>Pit</seg> </l:ev>
<l:ev dateTime="2019-06-14 09:30" pName="sin"> <mis>222222</mis><seg>sit</seg> </l:ev>
<l:ev dateTime="2019-06-14 10:30" pName="vin"> <mis>333333</mis><seg>zit</seg> </l:ev>

output expected:
Code:
2019-06-14 08:30,11111111,Pit
2019-06-14 10:30,333333,zit


Also, one more thing if file is changed and it have contain like this(<val:mis>) as mentioned below then using above command is not working.

Code:
<l:ev dateTime="2019-06-14 08:30" pName="vin"> <val:mis>11111111</val:mis><val:seg>Pit</val:seg> </l:ev>

how about a brute-force approach - YMMV:
Code:
 awk -F'["<>]' '$5=="vin" {print $3, $9, $13}' OFS=, myFile.txt

Or an adaptation to the sed command:
Code:
sed -n 's:.*dateTime="\([^"]*\).*<mis>\(.*\)</mis>.*<seg>\(.*\)</seg>.*:\1\,\2,\3:p'

Different approach, including your val: case:
Code:
sed -n 's/" pName="vin">//; T; s/^.*dateTime="//; s/<[^>]*>/,/g; s/[ ,]\{2,\}/,/gp' file
2019-06-14 08:30,11111111,Pit,
2019-06-14 10:30,333333,zit,
2019-06-14 08:30,11111111,Pit,

Thanks for this.......Can use AWK but sometimes for few lines sequence may change or an extra element might get added that may cause the issue with the expected output.

Thanks for this ......but this is not working when val is added. For example if you file contains these:
Code:
<l:ev dateTime="2019-06-14 08:30" pName="vin"> <mis>11111111</mis><seg>Pit</seg> </l:ev>
<l:ev dateTime="2019-06-14 09:30" pName="vin"> <val:mis>222</val:mis><val:seg>sit</val:seg> </l:ev>
<l:ev dateTime="2019-06-14 09:30" pName="vin"> <nim:mis>222</nim:mis><nim:seg>sit</nim:seg> </l:ev>

Yes, it doesn't work, because your search string is "<mis>" and what the file contains is "<val:mis>" (and "<seg>" instead of "<val:seg>", etc.). It is rather obvious that you find only what you search for, nothing else. No?

But isn't it obvious how the command above must be changed to reflect the changes in your input? I am convinced that a brilliant young man like you can do that, can't you? Just show us what you tried.
