The skipTags() you wrote doesn't return its result.

Without actually trying it I think this will work:


// redo, skip TAGS
char *skipTags( char *s )
{
        if( *s == '<' ) {
                while( *s && ( *s++ != '>' ) )
                     ;		// on a line of its own to make sure you see it
        }
        return s;
}

When not using a count to indicate how much data is in a char* you  
should always test for null. Testing for null is not a sure fire way  
to prevent buffer over runs but its better than nothing.

Use the above something like this:

char *buffPtr;

	buffPtr = skipTags( buffPtr );	//  advance over < > tags
