Can figure out why my XML template is not printing the whole XML structure for the last element in the array?

Hi,

I am using pyton to code a small script which fills up an xml template which I define. The python code read an C file which has an array of strings seperated my commas. Something like this shown below.

    array myvector[] = {
    
    {"1" , "March", "1st", "2017"},
    {"2" , "March", "2nd", "2017"},
    {"3" , "March", "3rd", "2017"},
    .....
    {"1" , "April", "1st", "2017"},
    ....
    {"31" , "December", "31st", "2017"}
     {NULL , NULL, NULL, NULL}
    };


My python script replaces the strings like "March", "April", and ... till "December" in the {month} and number 1st, 2nd, 3rd, ... in the {day} part in the xml structure.

The funny thing is when I run my script, everything looks good except the last two days of December. The xml structure is only partly printed out. When I add an extra space or remove and extra sapce from **xmlTemplate** the printout of the xml structure for the last entries like the days in December get partly printed. I have no idea what is going wrong. Does it have to do with the formating of the xmlTemplate. Could someone advice me on what to do?

What I have tried:

I tried formating the spaces in the template but it does not help.

You should show the code that generates the output file.

One reason for such behaviour is reading a file that is still opened (has not yet been closed).

To have a clear understand of what I am telling, I have posted the output I get the output file below as an answer so it allows better formating. Could you please advice me on how to solve it?

1. Don't post such as a solution
Use the green "Improve question" link to edit your question and delete the solution (it will probably reported as "not an answer").

2. It does not help much to solve the problem when seeing what is printed while not knowing how it is generated.

Hi, I just posted my full code above in the edited question. I think this will give a better idea now? I would be grateful to you if you could help me resolve this bug. Thanks alot!

Where is mytestfile opend and closed?

When and where do you read the content of the file?

When you are not closing the file with mytestfile.close() and reading it from the same python script or while the script has not executed you will get that behaviour as already noted.

Sir you are a genius!!!!!!!!!!!!!!! I forgot to close a file! How could I be so stupid! Problems is solved now!!!!!!!!!!!!!!!! YAYAYYYYYY!!! All Hail Jochen!!!!!!!!!!!!!!!

I just had one last question. I want to be able to add the namespace to the xml template. I want it to be at the beginning and at the end of the file. Could you tell me on how to do it?

I want my output file to look something like this:

<MyCalender xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http:/...my.xsd" xmlns="http:/..eyts">

........all the xml tags go here.........

Could you help me by advising how to add this?

Jochen Arndt 10-Mar-17 10:47am

Just write that string after opening the file before processing the input file. There is no need to write that also at the end of the file.

Member 13051048 10-Mar-17 10:50am

i did that but I am not able to encapsulate the strings correctly as the xmlns and xsi ahve their own "". Could you give me a template?

Jochen Arndt 10-Mar-17 10:56am

You have to esacpe the double quote characters with a backslash:

mytestfile.write("<MyCalender xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http:/...my.xsd\" xmlns=\"http:/..eyts\">")

or use single quotes (then single quotes inside the string must escaped):

mytestfile.write('<MyCalender xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http:/...my.xsd" xmlns="http:/..eyts">')

Hi, I resolved the issue. Thanks for the help.

Member 13051048 10-Mar-17 9:56am

I tried to open and close the file but that does not still resolve the issue. The funny thing is when I add a space and reformat the tag, some more days disappear in December.

The code to write to the file is: myFilename.write((xml.format(month=tag, day=name))) where tag and name are the etracted parts from the array which I need and which is eventually the "March", "April",... and the days "1st", "2nd",... .

Solution 2

See the comments.

The problem source was not closing the output file before reading it later:

Python

for line in f:
    # ...
    mytestfile.write((xmlTemplate.format(month=monthone, day=dayone)))
    # ...
# Close files here
f.close()
mytestfile.close()
