Not sure what you mean by 'dynamic' in this case, but have you considered using CSS selectors?

With Beautifulsoup you could get it e.g like this:

soup.select('div#quote-header-info section span')[0]  

And there are some variations you could use on the pattern, such as using the '>' filter.

You could get the same with just lxml, no need for BeautifulSoup:

import lxml.html as html
page = html.parse(url).getroot()
content = page.cssselect('div#quote-header-info section > span:first-child')[0].text

Which immediately illustrates a more specific selector.

If you're interested in more efficient DOM-traversal, research xpaths.
