#includeusing namespace std; bool isSVGElement(Node node) { if(node.namespaceURI() == "http://www.w3.org/2000/svg") { return true; } return false; } int main() { // Assuming there is an SVG image loaded into memory. Node image = loadImageFromMemory(); if(isSVGElement(image)) { cout << "This is an SVG element." << endl; } else { cout << "This is not an SVG element." << endl; } return 0; }
#includeIn this example, we have a vector of Node objects and we are using the STL algorithm `find_if` to search for an SVG element. The `find_if` function takes a callable object (in this case, the function isSVGElement) and returns an iterator to the first element in the range for which the callable returns true. If no such element is found, the function returns the end iterator. Here, we are using the `auto` keyword to define the type of the iterator since it's quite long and cumbersome to write out. Package/Library: This function relies on the parent class Node, which is provided by the Document Object Model (DOM) API. Therefore, understanding how to use Node isSVGElement requires an understanding of DOM and its usage in C++ programming.#include #include using namespace std; bool isSVGElement(Node node) { if(node.namespaceURI() == "http://www.w3.org/2000/svg") { return true; } return false; } int main() { //Assuming a list of nodes is available vector nodeList = getNodeList(); auto svgNode = find_if(nodeList.begin(), nodeList.end(), isSVGElement); if(svgNode != nodeList.end()) { cout << "Found an SVG element." << endl; } else { cout << "No SVG elements found." << endl; } return 0; }
