I wanted only to report this as a good news/bad news factoid:
Yeah, I wasn't negative about the posting more about the fact that
they apparently didn't tried to use libxml directly, i.e. they didn't
bothered looking at the native APIs
good news: libmxml is considered mainstream, even on Win32
bad news: rather weak comparative benchmark doesn't give real information.
Not much to me because I don't know what they benchmarked.
Reading the file into a tree, walking the tree, thawing objects:
void read_file(char const *input_name, FILE *output)
Node *root = parser.get_root_node();
Node::NodeList children = root->children("entry");
you see, for me it's very hard to map that to the associated calls
in libxml2, I can't even tell where the document is actually parsed,
nor what root->children("entry"); actually does, is taht a call to XPath ?
or a direct walk of the children nodes, or ...
Node::NodeList::const_iterator begin = children.begin();
Node::NodeList::const_iterator end = children.end();
for(int i = 0; begin != end; ++begin, ++i)
Node const *node = *begin;
Attribute const *year = node->attribute("year");
Attribute const *month = node->attribute("month");
Attribute const *day = node->attribute("day");
Attribute const *who = node->attribute("who");
I can think of ways to significantly speed up attribute value
lookup in the general case too..
ATM I'm working on features, maybe I will have time to do some
speedup work before the summer..
