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 https://webkeks.org/objfw/.
The current limitations are:
- Incomplete error checking
- Unstable API
The Minimal Supported Rust Version for this crate is Rust 1.40.0.
Parse a string into an Element struct:
use xml::Element;
let elem: Option<Element> = "<a href='//example.com'/>".parse();Get events from parsing string data:
use xml::{Event, Parser};
// Create a new Parser
let mut p = Parser::new();
// Feed data to be parsed
p.feed_str("<a href");
p.feed_str("='//example.com'/>");
// 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:
<a>
</a>
Build Elements from Parser Events:
use xml::{Parser, ElementBuilder};
let mut p = xml::Parser::new();
let mut e = xml::ElementBuilder::new();
p.feed_str("<a href='//example.com'/>");
for elem in p.filter_map(|x| e.handle_event(x)) {
match elem {
Ok(e) => println!("{}", e),
Err(e) => println!("{}", e),
}
}Build Elements by hand:
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):
<iq xmlns='jabber:client' id='42' type='error'>
<error type='cancel'>
<forbidden xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
<text xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'>Permission denied</text>
</error>
</iq>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.
