[![Build Status](https://travis-ci.org/Florob/RustyXML.svg?branch=master)](https://travis-ci.org/Florob/RustyXML)



[Documentation](https://docs.babelmonkeys.de/RustyXML/xml)



RustyXML is a namespace aware XML parser written in Rust.

Right now it provides a basic SAX-like API, and an ElementBuilder based on that.



The parser itself is derived from OFXMLParser as found in ObjFW

.



The current limitations are:

* Incomplete error checking

* Unstable API



The Minimal Supported Rust Version for this crate is Rust 1.40.0.



Examples

--------

Parse a string into an `Element` struct:

```rust

use xml::Element;



let elem: Option = "".parse();

```



Get events from parsing string data:

```rust

use xml::{Event, Parser};



// Create a new Parser

let mut p = Parser::new();



// Feed data to be parsed

p.feed_str("");



// Get events for the fed data

for event in p {

    match event.unwrap() {

        Event::ElementStart(tag) => println!("<{}>", tag.name),

        Event::ElementEnd(tag) => println!("{}>", tag.name),

        _ => ()

    }

}

```



This should print:

```





```



Build `Element`s from `Parser` `Event`s:

```rust

use xml::{Parser, ElementBuilder};



let mut p = xml::Parser::new();

let mut e = xml::ElementBuilder::new();



p.feed_str("");

for elem in p.filter_map(|x| e.handle_event(x)) {

    match elem {

        Ok(e) => println!("{}", e),

        Err(e) => println!("{}", e),

    }

}

```



Build `Element`s by hand:

```rust

let mut reply = xml::Element::new("iq".into(), Some("jabber:client".into()),

                                  vec![("type".into(), None, "error".into()),

                                       ("id".into(), None, "42".into())]);

reply.tag(xml::Element::new("error".into(), Some("jabber:client".into()),

                            vec![("type".into(), None, "cancel".into())]))

     .tag_stay(xml::Element::new("forbidden".into(),

                                 Some("urn:ietf:params:xml:ns:xmpp-stanzas".into()),

                                 vec![]))

     .tag(xml::Element::new("text".into(),

                            Some("urn:ietf:params:xml:ns:xmpp-stanzas".into()),

                            vec![]))

     .text("Permission denied".into());

```

Result (some whitespace added for readability):

```xml



  

    

    Permission denied

  



```



Attribute Order

---------------



By default the order of attributes is not tracked. Therefore during serialization and iteration

their order will be random. This can be changed by enabling the `ordered_attrs` feature.

With this feature enabled the order attributes were encountered while parsing,

or added to an `Element` will be preserved.
