Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:
Rust

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

if xml.load_xml_file("qa_data/xml/pigs.xml").is_err() {
    println!("{}", xml.last_error_text());
    return;
}

// Get the content of the "species" node for the 1st animal:
let mut result = String::new();
result = xml.chilkat_path("animal|species|*").unwrap_or_default();
// Output should be "pot belly pig"
println!("{}", result);

// Get the content of the "type" node for the 2nd animal:
// Indexing begins at 0.  Therefore, the 2nd direct child having
// the tag "animal" is at index 1
result = xml.chilkat_path("animal[1]|type|*").unwrap_or_default();
// Output should be "House Pig"
println!("{}", result);

// Find the pig having the name "Nigel" and display the
// birth date.  To do this, we'll navigate to the node having
// tag="name" with the exact content "Nigel", then navigate up, 
// and finally navigate back down to the "birth" node:
result = xml.chilkat_path("/C/name,Nigel|..|birth|*").unwrap_or_default();
// Output should be "June, 1991"
println!("{}", result);

// Navigate to the 1st animal's picture and print the filename,
// description, and caption.
// The "$" updates the caller's internal pointer to reference
// the node that is the result of evaluating the path.
// An empty string is returned for success, and a NULL/nil/0
// pointer (reference) is returned on failure.  
result = xml.chilkat_path("animal|picture|$").unwrap_or_default();
if !xml.last_method_success() {
    println!("Failed to navigate to animal|picture.");
    return;
}

// Display the contents of the file/description/caption child nodes
println!("Picture Info:");
println!("{}", xml.get_child_content("file").unwrap_or_default());
println!("{}", xml.get_child_content("description").unwrap_or_default());
println!("{}", xml.get_child_content("caption").unwrap_or_default());

// Return back to the root of the XML document:
xml.get_root2();

// Display the value of the "spay-neuter" attribute of the 1st animal:
println!("----");
result = xml.chilkat_path("animal|gender|(spay-neuter)").unwrap_or_default();
println!("{}", result);
