Some functions I need to make to replace the PHP functions I had used before.

xml_utils.h

#ifndef xml_UTILS_H
#define xml_UTILS_H

#include <stdlib.h>

#include <string.h>


// c doesn't have bools...
typedef enum {notags, tags} tag_bool_t;

///gets the string between a start and end tag in a string str
///returns a null-pointer if no occurances found.
char* strBetween(const char const* str, const char* start, const char* end, tag_bool_t includeSE){

	// copy the string into ans
	char* ans = (char*) malloc( strlen(str) + 1 );
	strcpy(	ans, str);

	//include the the start & end tags
	if (includeSE) {
		char* begin = strstr(ans, start);
		//start search @ begin as end tag is after start
		char* stop = strstr(begin, end);
				
		if (begin == (char*) NULL || stop == (char*) NULL)
			return (char*) NULL; //no occurances found

		//include the end tag as well...
		stop += strlen(end);
		*stop = '\0'; //terminate the string

		return begin;
	} // else:

	//remove start string
	char* begin = strstr(ans, start);
	begin += strlen(start);

	//start search @ begin as end tag is after start
	char* stop = strstr(begin, end);


	if (begin == (char*) NULL || stop == (char*) NULL) 
		return (char*) NULL; //no occurances found

	*stop = '\0'; //terminate the string

	return begin;

}

#endif

xmlUtils.c

#include <stdio.h>
#include "xml_utils.h"

int main(){

	char* testString = "boring... <cool>good stuff here</cool>lame stuff here";
	
	printf("\nThe string is: \"%s\"\n\n", testString);

	printf("The cool stuff (with tags) = \"%s\"\n\n", 
		strBetween(testString, "<cool>", "</cool>", tags)
	);

	printf("The cool stuff (no tags) = \"%s\"\n\n", 
		strBetween(testString, "<cool>", "</cool>", notags)
	);
	

}

I think I'll make a repository for my website...
