Dear All,
I am developing an application that reads XML file tags. I have a tag e.g
<small>rohit</small>
the application reads fine, i.e gives "rohit" as output.
But I want to check if "Enter" is also pressed in this tag i.e
<small>rohit
</small>
i.e after entering the tagname i.e "rohit", user has pressed enter key also. So I want to check if the user has also "entered" along with some tag name, but unfortunately i am not able to see if next line is also printed or not.
I am trimming the free space if provided in these tags, like
Wrote a code for this as
/////////
while((!isgraph((int)str[i
i++;//trim the spaces on left
strcpy(tempStr, &str[i]);
i = len-i-1;
while((!isgraph((int)tempS
i--;//trim spaces to the right
////////
I tried to see if
if (str[0] =='\n') but it didnot helped.
Please suggest to handle the "next line character" ,Let me know if my query needs more clarification.
Regards,
RDH

Hi rohitdivas,
Assuming that string "rohit" or "rohit\n" is in variable str of type char *.
int i = strlen (str);
if ( str[i-1] == '\n' )
printf ("newline found");
Incase it is possible that \n can occur in the middle of str, then you will have to traverse char by char
int i =0;
while ( str[i] != '\n' && str[i] != '\0' )
i++;
if (str[i] == '\n')
printf ("newline found");
Cheers!

You might want to read up on Parsers and Lexical analysers and look at tools such as ylex etc.
Essentially what you are doing is parsing the XML file which requires looking for tokens and dealing with each token in turn.
A parser / lexical analyser is actually quite simple to create and it does make the task you are trying to perform a lot easier. It is also a lot easier to extend the application to cater for additional tokens in the future.
If you want to go this route look at the following links
http://www.codeguru.com/Cp
http://www.thecodeproject.
http://www.ultimatereposit
http://www.thefreecountry.
Just to quote a few - you can find more by searching for parser, lexical analyser etc.
yeah julian understood my problem to some extent.
<?xml version="1.0" encoding="UTF-8"?>
<small> rohit
</small>
next line doesnot mean directly capturing it and comparing its ascii value. Actually we get some un-recognized characters when we the xml file for nextline character
I want a function that change that UTF next line character so that It could be readabe and i could capture it.
rohit

I really can't help with anything but to say:
ASCII Value of Enter Key is a Carriage Return, typically. That is value 13 (Decimal).
Windows often uses Carriage Return - Line Feed, which is ASCII 13 decimal, ASCII 10 Decimal.
