Methods for Getting Attributes

See more XML Examples

Demonstrates some methods for getting attribute name/values.

The input XML, available at http://www.chilkatsoft.com/data/car.xml, is this:

<root>
    <car color="black" make="mercedes" model="C350" hp="302" engine="v6" type="sedan">Mercedes Benz C350</car>
</root>

Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const xml = try chilkat.Xml.init();
    defer xml.deinit();
    var i: i32 = 0;

    // The sample input XML is available at http://www.chilkatsoft.com/data/car.xml
    xml.loadXmlFile("car.xml") catch {
        std.debug.print("{s}\n", .{try xml.getLastErrorText(alloc)});
        return;
    };

    // Navigate to the "car" node, which is the 1st child:
    const car_node = try xml.firstChild();
    defer car_node.deinit();

    // Get the value of the "model" attribute:
    std.debug.print("model = {s}\n", .{try car_node.getAttrValue(alloc, "model")});

    // Get the value of the "hp" attribute as an integer:
    const horsepower = car_node.getAttrValueInt("hp");
    std.debug.print("horsepower = {d}\n", .{horsepower});

    // Iterate over the attributes and show the name/value of each:
    const num_attr = car_node.getNumAttributes();

    i = 0;
    while (i < num_attr) {
        std.debug.print("{s}: {s}\n", .{ try car_node.getAttributeName(alloc, i), try car_node.getAttributeValue(alloc, i) });
        i = i + 1;
    }
}
