Function yrs::yxmlelem_insert_attr

#[no_mangle]
pub unsafe extern "C" fn yxmlelem_insert_attr(
    xml: *const XmlElement, 
    txn: *mut Transaction, 
    attr_name: *const c_char, 
    attr_value: *const c_char
)

Inserts an XML attribute described using attr_name and attr_value. If another attribute with the same name already existed, its value will be replaced with a provided one.

Both attr_name and attr_value must be a null-terminated UTF-8 encoded strings. Their contents are being copied, therefore it’s up to a function caller to properly release them.
