Get content from span with no class?

I got some HTML that reads <span class=""...></span>

I want to use JSoup to get what is between these two tags, but I only have one other identifier on those span classes, and it's <...attr="?"...></span>

The ? is an auto generated number starting at 0. How would I go about getting the content in the span tag? I seem to have few choices in identifiers.
