Note

Hello! This was a project made by Freja Roberts and want to first give credit for them. I'm still slowly updating this project because it's super intuitive but just needs updating.

Szl Simple XML

Szl Simple xml is a small crate for reading, parsing and storing xml as an extension from simple-xml. This extension adds getting mutable nodes

Usage

Example parsing:

let note =
    szl_simple_xml::from_file("./examples/note.xml").expect("Failed to parse simple_xml");

let to = &note["to"][0];
let from = &note["from"][0];
let heading = &note.get_nodes("heading").expect("Missing heading")[0];
let body = &note["body"][0];
let lang = note
    .get_attribute("lang")
    .expect("Failed to get attribute lang");

For additional examples, please see: Docs

lib.rs:

XML parser and writer This crate can load xml from a file or string and parse it into memory XML can also be manipulated or created and the written to file

Loading xml from a file

fn load_message() -> Result<(), simple_xml::Error> {
    let root = simple_xml::from_file("examples/message.xml")?;
    // Since there can multiple nodes/tags with the same name, we need to index twice
    let heading = &root["heading"][0];
    println!("Heading: {}", heading.content);
    // Access attributes
    let lang = root.get_attribute("lang").expect("Missing lang attribute");
    println!("Language: {}", lang);
    Ok(())
}

Creating xml structures

let name = String::from("Tim Roberts");
let health = 50;

let mut player = simple_xml::new("player", String::new());
player.add_new_node("health", health.to_string());
player.add_new_node("name", name);
// Save to file
player.save_to_file("./player.xml");

Editing xml structures

let file =     
   szl_simple_xml::from_file("./examples/note.xml").expect("Failed to parse simple_xml");
   let mut resources = 
       &mut file.get_mut_nodes("resources").unwrap()[0].get_mut_nodes("resource").unwrap()[0];
   
   let href = String::from("page1.html");
   let new_file_node = szl_simple_xml::new("file", String::new());
   new_file_node.add_attribute("href", &href);

   resources.add_node(new_file_node);
   let write_file = file.save_to_file_pretty("./test.xml")
