dummy_xml

这是一个快速的DOM XML解析器。这是对 pugixml 的一个糟糕的、不完整的克隆。

示例

如何解析

extern crate dummy_xml;

use dummy_xml::parser;

let result = parser::parse_str("<parent><child1 name='go'/><child2 name='rust'/></parent>");
match result {
    Ok(document) => {
        let root = document.root();
        println!("root is {:?}", root);
    }
    Err(error) => panic!("{:?}", error),
}

如何编写

use dummy_xml::writer;
use dummy_xml::node::Node;

let mut root = Node::new("parent");
root.append_child("child1")
    .append_attribute("gender", "male");
root.append_child("child2")
    .append_attribute("gender", "female");
root.append_child("child3")
    .append_attribute("gender", "non-gender");

let mut result = String::new();
writer::write(&root, &mut result);
println!("{}", result);

//expect to see: 
//<parent>
//    <child1 gender='male'></child1>
//    <child2 gender='female'></child2>
//    <child3 gender='non-gender'></child3>
//</parent>
