SUBJECT: RE: SaxParser: Access attribute prefixes I just found, that the underlying function start_element_ns_callback() in ruby_xml_sax2_handler.c processes the attributes as follows:
// ...
/* Each attribute is an array of [localname, prefix, URI, value, end] */
int i;
for (i = 0;i < nb_attributes * 5; i+=5)
{
VALUE attrName = rb_str_new2(xattributes[i+0]);
VALUE attrValue = rb_str_new(xattributes[i+3], xattributes[i+4] - xattributes[i+3]);
/* VALUE attrPrefix = xattributes[i+1] ? rb_str_new2(xattributes[i+1]) : Qnil;
VALUE attrURI = xattributes[i+2] ? rb_str_new2(xattributes[i+2]) : Qnil; */
rb_hash_aset(attributes, attrName, attrValue);
}
// ...
Because the prefix and the URI are commented out, it is logical that libxml-ruby does not provide them to the implementation of on_start_element_ns() callback. But why are they commented out? | |
