Wrap one line paragraphs in string with h tags

Hi,
I have text (string) like this:

Blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah.

Blah blah blah blah

Blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah.


So, we have 3 paragraphs, made by returns and newlines (could be html <p> tags, doesnt matter, we can convert it anyway). Now, every single-line paragraph we want to wrap with <h2> and </h2> tags - make a heading from it.

How could this be done? I have no idea.

Thank you for help.

STRTOK(3)						   BSD Library Functions Manual 						 STRTOK(3)

NAME
strtok, strtok_r -- string tokens LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> char * strtok(char *str, const char *sep); char * strtok_r(char *str, const char *sep, char **last); DESCRIPTION
This interface is obsoleted by strsep(3). The strtok() function is used to isolate sequential tokens in a null-terminated string, str. These tokens are separated in the string by at least one of the characters in sep. The first time that strtok() is called, str should be specified; subsequent calls, wishing to obtain further tokens from the same string, should pass a null pointer instead. The separator string, sep, must be supplied each time, and may change between calls. The implementation will behave as if no library function calls strtok(). The strtok_r() function is a reentrant version of strtok(). The context pointer last must be provided on each call. The strtok_r() function may also be used to nest two parsing loops within one another, as long as separate context pointers are used. The strtok() and strtok_r() functions return a pointer to the beginning of each subsequent token in the string, after replacing the token itself with a NUL character. When no more tokens remain, a null pointer is returned. EXAMPLES
The following uses strtok_r() to parse two strings using separate contexts: char test[80], blah[80]; char *sep = "\/:;=-"; char *word, *phrase, *brkt, *brkb; strcpy(test, "This;is.a:test:of=the/string\tokenizer-function."); for (word = strtok_r(test, sep, &brkt); word; word = strtok_r(NULL, sep, &brkt)) { strcpy(blah, "blah:blat:blab:blag"); for (phrase = strtok_r(blah, sep, &brkb); phrase; phrase = strtok_r(NULL, sep, &brkb)) { printf("So far we're at %s:%s ", word, phrase); } } SEE ALSO
memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), wcstok(3) STANDARDS
The strtok() function conforms to ISO/IEC 9899:1990 (``ISO C90''). AUTHORS
Wes Peters <wes@softweyr.com>, Softweyr LLC Based on the FreeBSD 3.0 implementation. BUGS
The System V strtok(), if handed a string containing only delimiter characters, will not alter the next starting point, so that a call to strtok() with a different (or empty) delimiter string may return a non-NULL value. Since this implementation always alters the next starting point, such a sequence of calls would always return NULL. BSD
