Adding #fetch support to XML::Node ?

[andyw8]

The docs say

A Nokogiri::XML::Node may be treated similarly to a hash with regard to attributes.

but one thing I miss from this hash-like behaviour is #fetch, which would raise an error if the given key doesn't exist. This can be helpful for avoiding nils being inadvertently passed around, leading to hard-to-find bugs.

Would this be worth adding?

Howdy! Thanks for bringing this up.

If you take a look at the roadmap for Nokogiri 2.0 (https://github.com/sparklemotion/nokogiri/blob/master/ROADMAP.md) you'll see that we definitely want to make the Node API better, particularly around attribute-hashiness (also see issue #666).

I'll add a reference to this issue in the roadmap, and leave this open for now. Cool?

Great, thanks.

I've noted this in the ROADMAP doc and as I approach what might be a 2.0 release later this year or early next year, I'm keeping this topic top-of-mind. However, in the meantime to lower the cognitive overhead of the backlog, I'm going to close this.
