Printing charcter by character

Hi.....
I have to parse through an input XML file line-by-line, character-by-character and find if closing HTML tags are present for every opening HTML tag.

Code:

MAIN program:
	while (scanf("%s", code) != EOF)
	{
		i=0;
		length = strlen(code);
		while (i < strlen(code))
		{
			c=code[i];
			if (c == '<')
			{
	                 j=0;

                                 do
	                         {
					c=code[i];
					element[j]=c;
					++i;
					j++;
				}while(c!='>');

				c=code[++i];

				element[j] = '\0';


				if (element[1] == '/')
				{
					l=element[2];
					length = strlen(element);
					for (k=0;k<=length-4;k++)
					{
						check[k]=element[l++];
					}
					check[k] = '\0';
					/*Function passsed tho process the element()*/
					printf("%s",element);

				}

				else
				{
					l=element[1];

					length = strlen(element);
					for (k=0;k<=length-3;k++)
					{
						check[k]=element[l++];

					}
					check[k]='\0';
					/*Function passsed tho process the element()*/
					printf("%s",element);
				}

			}
			else
			{
				putchar(c);
				c=code[++i];
			}

		}
	}

When printing to the output I find that any character that is printed just after '>' character without any spaces will not be printed to the output. Also no spaces from the input text is printed to the output.

Please help

c=code[++i] skips past the character after the > (since i was also incremented in the search for the closing > loop as well). It is not possible to read a space using %s.

For the spaces just use fget() reading and checking for the '\n' character.
(Generally I prefer fget(). You have more control and you just have to use it in a while-loop checking for EOF or '\n' to read a line)

well i tried removing the line ++i. But still same result. Also, only characters between < & > will be stored in an array and printed as &#37;s, rest will be displayed character-by-character.

If I were to use fgets(), I will have to use FILE input/ouput. The code will get more complicated then. Our assignment mentions to use standard input. so I can use scanf, gets(), etc.

How is that different than what you want?

That's the silliest thing I've ever heard.

I have to take each line from text as string, parse through it character-by-character. When it encounters <, search for >, make it as a string, if it does not have '!', push it into a stack, else pop the stack.the rest of the contents will be displayed character by charater.

eg. <title>I am a boy<!title>

Dont I have to FILE stream to use fgets()?

Use stdin as the argument for a FILE stream to fgets() if you want to read from standard in (which is usually the keyboard at the console).

Example:

Code:

fgets(..., ..., stdin);

can't I use any other functions besides FILE stream like gets() that will read even space character?

gets() is broken. Use fgets(). It doesn't require much more work, and it's proper and safe.
