Update an XML Attribute

See more XML Examples

Demonstrates how to update XML attributes.

The output XML is this:

<abc b="pear" c="orange" a="130">Test</abc>

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();

    try xml.loadXml("<abc a=\"123\" b=\"apple\">Test</abc>");

    // The UpdateAttribute and AddOrUpdateAttribute methods
    // are identical.  Both will replace the attribute's value if it
    // already exists, or insert a new attribute if it does not yet exist.

    // Change the value of attribute "b" to "pear".
    try xml.updateAttribute("b", "pear");

    // Because no attribute named "c" exists, UpdateAttribute
    // will create it:
    try xml.updateAttribute("c", "orange");

    // If an attribute's value is an integer, the AddToAttribute
    // method may be called to update it by adding an integer value.
    // For example, update the value of "a" to "130" by adding 7.
    xml.addToAttribute("a", 7);

    // Examine the result:
    std.debug.print("{s}\n", .{try xml.getXml(alloc)});
