Is there a setting or plugin in Sublime Text 3 that would allow me to achieve the following automatically?
<element attr1="value" attr2="value" attr3="value">…</element>

I don't know of a plugin, but you can search for (?<=\b") +\b and replace with \n\t which results in a formatting close to requested:
<element attr1="value" attr2="value" attr3="value">…</element> Necessary assumptions: 1) your input data was
<element attr1="value" attr2="value" attr3="value">…</element> 2) your element had had 0 indentation.
The regex highlights a sequence of 1 or more spaces between closing quotation marks to the left and a new word beginning to the right. You can also select them all and multi-insert enter and the 9 spaces needed in this very example. More cumbersome, restricted to one element at a time, but pretty.
If you expect any quotation marks outside of elements, you can use a more robust regex: (?<=\b") +\b(?=[^<]+>). It adds the condition that on the right you can find a closing angle bracket with no opening bracket before it.
