How to create XML file with C

Question

4.00/5 (1 vote)

See more:

I've searched, unfortunately I only found how to do that with C++ or C# - i's pretty different once are object oriented languages.

Can you please point me to the information?

I was simply putting strings:

fputs("<complexType name='DominantColorType” final='#all'>\n",fp);

But I get an "error" at '#'. Anyone know why ?

Writing XML with C (or any other programming language) is really simple, you don't need any library (on the other hand reading and parsing XML is a bit more complex).
As someone already noted, your did a mistake in your original XML expression.

Solution 3

Thought of:

XML

fputs("<complexType name='DominantColorType" final='#all'>\n",fp);

Take a closer look at DominantColorType"

you probably meant DominantColorType'

For a pure c implementation:
The XML C parser and toolkit of Gnome
[^]

and the there is this Apache Xerces[^] - it's C++ though

All you need to write your code by own and first of all you must know XML.

I just can give some hints

You need to define your macros like this

<pre lang="xml">#include <stdio.h>
#include <tchar.h>
#define START_NODE( \
     /*NULL TERMINATED STRING*/NodeName , \
     FilePointer) \
     fprintf( FilePointer , "<%s>\n" , NodeName ) \
#define END_NODE( \
     /*NULL TERMINATED STRING*/NodeName , \
     FilePointer) \
     fprintf( FilePointer , "</%s>\n" , NodeName ) \
int _tmain(int argc, _TCHAR* argv[])
{
    FILE *fp = NULL;     /*i use stdout in place of a file pointer
                         to show the result on concole*/
    START_NODE("t1", stdout);
    END_NODE("t1", stdout);
    getchar();
    return 0;
}

but using these MACROs you can't give attributes to nodes...

This will do if you don't need attributes....

If you want then use functions instead of macros...
