xml-doc

xml-doc is a rust library to read, modify, and write XML documents. Documentation

It's aim is to be able to read any xml files, and modify only the parts you want to.

Features:

• add log4rs support

Example

use xml_doc_log4rs::{Document, Element};

let XML = r#"<?xml version="1.0"?>
<package xmlns:dc="http://purl.org/dc/elements/1.1/">
    <metadata>
        <dc:title>xml-doc</dc:title>
        <dc:rights>MIT or Apache 2.0</dc:rights>
    </metadata>
</package>
"#;

let doc = Document::parse_str(XML).unwrap();
let package = doc.root_element().unwrap();
let metadata = package.find(&doc, "metadata").unwrap();
let title = metadata.find(&doc, "title").unwrap();
title.set_attribute("xml:lang", "en");

// Add an element to metadata: <dc:creator id="author">Yoonchae Lee</dc:creator>
let author = Element::build(&mut doc, "dc:creator")
    .text_content("Yoonchae Lee")
    .attribute("id", "author")
    .push_to(metadata);

let new_xml = doc.write_str();

Performance

To run benchmark: cd benches ; cargo bench.

Only roxmltree which doesn't support writing, is considerably faster than xml_doc. You can see the result of the benchmarks here.
