    let mut resp = reqwest::get(uri).unwrap();
    assert!(resp.status().is_success());
    let mut content = String::new();
    resp.read_to_string(&mut content);

    // let file = File::open(filename).unwrap();
    let mut channel = Channel::read_from(BufReader::new(content.as_bytes())).unwrap();
    filter_feed(&mut channel, item_filter);
    println!("{:?}", channel.to_string());
    channel
    // println!("{:?}", channel.items);
}

Identical XML to what I tested with can be found at: http://bitemyapp.com/rss.xml

Here's a gist just in case: https://gist.github.com/bitemyapp/d0cab492eeea16d1dc76b72dfd3ca3a9

Any ideas?

Happens if I attempt write_to as well,

    channel.write_to(::std::io::sink()).unwrap(); // // write to the channel to a writer

Can you try updating to last quick-xml? There were some fixes recently regarding escapes.

[bitemyapp]

Works now with these deps:

rss = { git = "https://github.com/bitemyapp/rss-1", rev = "f669d81995824e54b27b264e762ed354906610f7" }
quick-xml = "0.9.4"

Thank you!

FYI, you should be able to do cargo update (or even cargo update -p quick-xml') to get the latest quick-xml without needing to explicitly bump the version in the Cargo.toml. with cargo, 0.9.0 implies ^0.9.0, so 0.9.4 is compatible with 0.9.0

[bitemyapp]

@frewsxcv well, it literally doesn't work <0.9.4 so I'd like my package to say as much.
