Functions except for xml_read

Previous: Definitions ] [ Top: index ] [ Next: xml_write: Writing XML data to disk ]

So here's my budding XML manipulation API. First, the include files, then a list of pieces of code (defined on other pages) which get pulled in to build the source file.

July 18, 2001: Note that I'm getting more agnostic about the memory allocation used by XMLAPI; originally, of course, it was exclusively malloc-based, but with the Python wrapper I decided it was time to allow the compiler to specify variants.

Also for the Python wrapper, I'm not including any reference to the external expat library; these functions will be reimplemented on the pyexpat module instead, in native Python. This avoids a double linkage, as Python already includes its own version of expat.

These changes haven't been tested yet, or incorporated into the Python wrapper, so don't get too bent out of shape if they don't work.
#include <stdio.h>

#ifdef PYTHON


#include <malloc.h>
#define MALLOC(x) malloc(x)
#define REALLOC(x,y) realloc((x),(y))
#define FREE(x) free(x)

#include <python.h>
#define MALLOC(x) PyMem_Malloc(x)
#define REALLOC(x,y) PyMem_Realloc((x),(y))
#define FREE(x,y) PyMem_Free(x)

#include <string.h>
#include <stdlib.h>
#include <stdarg.h>

#ifndef PYTHON
#include <expat.h>

#include "xmlapi.h"

/* Note to self: put these *after* xmlapi.h... (What was I thinking?) */
XMLAPI char * xml_strdup (const char * str)
   char * ret;

   ret = MALLOC (strlen (str) + 1);
   strcpy (ret, str);
   return (ret);
XMLAPI void xml_strfree (char * str)
   free (str);
