xml-doc

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

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

Features:

• Supports reading from most encodings, including UTF-16. (With the notable exception of UTF-32)
• You can have references to the parts of the tree, and still mutate the tree.
• Elements stores reference to its parent element, so traveling up the tree is fast.
• One of the fastest XML tree-like parser & writer. See #Performance.
• Supports attribute value normalization, character/entity references.

Due to its architecture, you can't exchange nodes or elements between documents. If your project modifies multiple xml documents at the same time, this library may not be a good fit.

Example

```rust use xml_doc::{Document, Element};

let XML = r#" xml-doc MIT or Apache 2.0 "#;

let doc = Document::parsestr(XML).unwrap(); let package = doc.rootelement().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: Yoonchae Lee let author = Element::build(&mut doc, "dc:creator") .textcontent("Yoonchae Lee") .attribute("id", "author") .pushto(metadata);

let newxml = doc.writestr(); ```

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