easier text printing

[chriscamacho]

by accessing the string structs (defining the whole struct in end user code)

struct xml_string {
	uint8_t const* buffer;
	size_t length;
};

the end user can then print a string like so....

struct xml_string* anc = xml_node_attribute_content(tchild, k);
printf("%*.*s ", 0, (int)anc->length, (char*)anc->buffer);

I think this would make the examples easier to follow...

Thanks for the input. In order to increase ABI stability, the definition of struct xml_string is not exposed.

Nevertheless a utility method returning the a content's of a node as zero terminated char* copy (to be freed by the caller) might be useful, since it's quite rare to have 0 inside XML content.

Patches welcome.

as well as that something like the following would be useful too...

static inline float xmlStrToFloat(struct xml_string* str) 
{
    uint8_t* str_0 = RL_CALLOC(xml_string_length(str) + 1, sizeof(uint8_t));
    xml_string_copy(str, str_0, xml_string_length(str));
    float f = strtof((char*)str_0, NULL);
        RL_FREE(str_0);
    return f;
}

...

static inline bool xmlStrEqu(const char* cmpstr, struct xml_string* str)
{
    if (strncmp(cmpstr, (char*)str->buffer, str->length )==0) {
	    return true;
    } else {
	    return false;
    }
}

I find comparing attribute and node names very useful when parsing the xml when loading a "level"
xmlstr to float (which can be cast to int if needed...) is also useful for attribute contents...
