XML NewChildBefore

Demonstrates the Chilkat.NewChildBefore method. Rust

let xml = chilkat::Xml::new();

xml.set_tag("order");
xml.new_child2("order_billing_info|price_list", "Listino Italia");
xml.new_child2("order_billing_info|price_list_id", "1");

println!("{}", xml.get_xml().unwrap_or_default());

// <?xml version="1.0" encoding="utf-8"?>
// <order>
//     <order_billing_info>
//         <price_list>Listino Italia</price_list>
//         <price_list_id>1</price_list_id>
//         <first_name>Francesco</first_name>
//     </order_billing_info>
// </order>

// If there is no "customer_id" element under "order_billing_info", then add it.
if xml.has_child_with_tag("order_billing_info|customer_id") {
    println!("customer_id already exists, nothing to do...");

// Add the customer_id element just before the "price_list" element.

// Get the "order_billing_info" element

// Call NewChildBefore to add an XML element <customer_id> before <price_list>
// First get the index of the element price_list
let index = order_billing_info.tag_index("price_list");
println!("index = {}", index);

// Add the "customer_id" element just before specified index.
let x_cust_id = order_billing_info.new_child_before(index, "customer_id", "1234").unwrap();
