#includeIn this example, we are parsing an XML document using the pugixml library. We then retrieve a specific element and its value. Finally, we check if the last child node is an etag. The package/library used in this example is pugixml.#include int main() { pugi::xml_document doc; const char* xml_string = " "; pugi::xml_parse_result result = doc.load_string(xml_string); if (result) { pugi::xml_node bar = doc.child("foo").child("bar"); std::cout << "Node: " << bar.name() << ", Value: " << bar.child_value() << "\n"; pugi::xml_node etag = bar.last_child(); if (etag.type() == pugi::node_etag) { std::cout << "This is an etag: " << etag.name() << "\n"; } } else { std::cout << "Error parsing XML: " << result.description() << "\n"; } return 0; } A simple XML document
