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>

Rust

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

let _ = xml.load_xml("<abc a=\"123\" b=\"apple\">Test</abc>").is_ok();

// 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".
let _ = xml.update_attribute("b", "pear").is_ok();

// Because no attribute named "c" exists, UpdateAttribute
// will create it:
let _ = xml.update_attribute("c", "orange").is_ok();

// 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.add_to_attribute("a", 7);

// Examine the result:
println!("{}", xml.get_xml().unwrap_or_default());
