I am working on xml file but unfortunately my xml file is become large. So now I want to split my xml file into multiple smaller xml files. Is it possible to split one large xml file into multiple smaller xml files.
For E.g. If we make any project in c language then we create multiple c files but the main function will always be present in one c file. All other functions or sub programs we keep in different c files. So if we have to call any function we call it from the c file which is having main function.
Same or similar to that I want in my xml file where there will be one main xml file and all other xml file would be dependent on the main xml file.
In simple words I want to split my large xml file into smaller xml files. I don't have any idea about it. I request you all that please share an example or link for any example of this kind of thing.
Thanks
If you just want to split the file into smaller parts you can use the split command in terminal.
Usage: split [OPTION] [INPUT [PREFIX]]
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default
size is 1000 lines, and default PREFIX is `x'. With no INPUT, or when INPUT
is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
-a, --suffix-length=N use suffixes of length N (default 2)
-b, --bytes=SIZE put SIZE bytes per output file
-C, --line-bytes=SIZE put at most SIZE bytes of lines per output file
-d, --numeric-suffixes use numeric suffixes instead of alphabetic
-l, --lines=NUMBER put NUMBER lines per output file
--verbose print a diagnostic to standard error just
before each output file is opened
--help display this help and exit
--version output version information and exit

Is there any possibility to read files from .csv into array of variables?
Instead of getting:
https://loadtest.com/mo/75245.json
https://loadtest.com/mo/190554MHG.json
https://loadtest.com/mo/190223MJG.json
https://loadtest.com/mo/198533FTR.json
...
I would like to get an array:
https://loadtest.com/mo/75245.190554MHG.190223MJG.198533FTR.19023.HGTYTRWEYRWEHF.1922MHGDGO.json
Does anybody have some idea?
Thank you in advance.
Check out the following JMeter Functions:
__FileToString() - to read your CSV file into a JMeter Variable
__split() - to "split" the aforementioned JMeter Variable holding CSV file content into separate variables using any suitable delimited (comma, tabulation symbol, newline, whatever)
A workaround for this, if you don't want to use Groovy, can be using text editor that supports regex (like Notepad++) to restructure your CSV, so that multiple lines are collapsed into a single multi value line.
An example for Notepad++ would be replacing all instances of:
^(.+)\R(.+)\R(.+)\R
With
$1 $2 $3
To collapse every 3 lines of text into a single line.
Then you can just use that one line as a single variable in JMeter. This way I've passed multiple comma separated Ids into an array in an Http request. Remember to use a different delimiter in JMeter CSV Data Set Config for actual CSV columns, than the one used to delimit your multiple values.
Could someone help me in writing a program that has to compile all the files in the directory and report error, if any. For which my program has to get the list of all files under the folder with its full path and store it in a temp-table and then it has to loop through the temp table and compile the files.
Below is a very rough start.
Look for more info around the COMPILE statement and the COMPILER system handle in the online help (F1).
Be aware that compiling requires you to have a developer license installed. Without it the COMPILE statement will fail.
DEFINE VARIABLE cDir AS CHARACTER NO-UNDO.
DEFINE VARIABLE cFile AS CHARACTER NO-UNDO FORMAT "x(30)".
ASSIGN
cDir = "c:\temp\".
INPUT FROM OS-DIR(cDir).
REPEAT:
IMPORT cFile.
IF cFile MATCHES "*..p" THEN DO:
COMPILE VALUE(cDir + cFile) SAVE NO-ERROR.
IF COMPILER:ERROR THEN DO:
DISPLAY
cFile
COMPILER:GET-MESSAGE(1) FORMAT "x(60)"
WITH FRAME frame1 WIDTH 300 20 DOWN.
END.
END.
END.
INPUT CLOSE.
Since the comment wouldn't let me paste this much into it... using INPUT FROM OS-DIR returns all of the files and directories under a directory. You can use this information to keep going down the directory tree to find all sub directories
OS-DIR documentation:
Sometimes, rather than reading the contents of a file, you want to read a list of the files in a directory. You can use the OS–DIR option of the INPUT FROM statement for this purpose.
Each line read from OS–DIR contains three values:
*The simple (base) name of the file.
*The full pathname of the file.
*A string value containing one or more attribute characters. These characters indicate the type of the file and its status.
Every file has one of the following attribute characters:
*F — Regular file or FIFO pipe
*D — Directory
*S — Special device
*X — Unknown file type
In addition, the attribute string for each file might contain one or more of the following attribute characters:
*H — Hidden file
*L — Symbolic link
*P — Pipe file
The tokens are returned in the standard ABL format that can be read by the IMPORT or SET statements.
So I have to write a C program to read data from .csv files supplied to me by multiple users, into matrices on which I will perform some operations (like matrix addition, multiplication with necessary conditions on dimensions, etc.) and print these matrices (or the output data) in to .csv files again.
I also need to dynamically allocate memory to my matrices.
Now, I have zero background in dealing with .csv files. I do not at all know the required code to read a .csv file or write into a .csv file. I have searched for long on the Internet but surprisingly I have not found any program that teaches how to deal with .csv files from the elementary level.
I am lost on this and need a lot of guidance, maybe a sample, fully well-written C program as I need a comprehensive example to begin with.
A CSV file is just a plain ASCII text file that contains a grid of values. Think of the file as a set of rows in a database table where each line in the file represents one record and the order of the data in each line is identical. Each item of data is separated using a comma character (hence the name). So to read the file:-
open file
until the end of the file
read line into a string
split the string into sub strings where ',' is the dilimiter
parse each sub string
Since there is no formatting information in a CSV file, if the data in each value consists of a string, then what do you do if the value has a comma in it? For reading numbers that is not a problem for you.
You could read the file in several passes, the first to determine the amount of data there is (number of columns, number of rows, etc) and the second to actually read the data.
Writing the CSV is quite simple:-
open file
for each record to write
for each element to write
write element
if not last element
write a comma
write a new line
I used the ls | wc -1 command to count the number of files in a directory. Is there a command to count the number of different file types ? Say the directory has 2 text files and one jpeg, the output should be 2 (text and jpeg are the different file types).
Any help is much appreciated. Thanks !
There is no single command (although you can certainly create one!) to do what you want, but it is quite simple to get your result. Decide exactly how you want to distinguish file type (filename extension, file content, name, etc.), then use common tools to count the result. If you are happy with the results printed by the file command, perhaps something as simple as:
file * | awk '{$1=""}1' | sort -u | wc -l
The awk filters out the first column of output (the filename) and the remaining processes in the pipeline count the results. This is fragile and will break if any of your filenames contain whitespace, so you might want to use : for the field separater in awk (in which case the solution is fragile and will fail if any filename contains a colon.)
Use file to find out the file types. Pipe that through grep to filter out things like images etc. and then do a wc -l.
What is the maximum length allowed for filenames? And is the max different for different operating system? I'm asking because I have trouble creating or deleting files, and I suspect the error was because of long file names.
1. Creating:
I wrote a program that will read a xml source and save a copy of the file. The xml contains hundreds of <Document>, and each have childnode <Name> and <Format>, the saved file is named based on what I read in the xml. For example, if I have the code below, I will save a file called test.txt
<Document>
<Name>test</Name>
<Format>.txt</Format>
</Document>
I declared a counter in my code, and I found out not all files are successfully saved. After going through the large xml file, I found out the program fail to save the files whose <Name> are like a whole paragraph long. I modify my code to save as a different name if <Name> is longer than 15 characters, and it went through no problem. So I think the issue was that the filename is too long.
2. Deleting
I found a random file on my computer, and I was not able to delete it. The error says that the file name was too long, even if I rename the file to 1 character. The file doesn't take up much space, but it was just annoying being there and not doing anything.
So my overall question is: What is the maximum and minimum length for filenames? Does it differ based on the operating system? And how can I delete the file I mentioned in 2?
It depends on the filesystem. Have a look here: http://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits
255 characters is a common maximum length these days.
