Text Object for HTML/XML attributes, e.g. data-foo="bar baz caz"

Question

Is there a plugin or a way to work with HTML text objects, e.g.

Say the cursor is in one of the attributes below:

<div data-foo="bar baz caz" class="a b c">

I wish to treat data-foo="bar baz caz" or class="a b c" as text objects, e.g. change inner attribute group, or change a attribute group.

Answer 1

The vim-textobj-xmlattr plugin does exactly that.

This vim plugin provides two text objects: ax and ix. They represent XML/HTML attributes.

ix works with the inner attribute, with no surrounding whitespace. ax works like aw does: it includes the whitespace before the attribute. I know that aw includes the whitespace after/before or whatever it finds more fitty, but XML/HTML attributes always include whitespace before them, while they do not always include whitespace after.
