The split line with the findnodes() function shows how to do that. It takes an XPath as an argument. As is, the perl script shows the number of shares traded (volume) and average volume over the last 30 days.
Code:
//tr[td[@data-snapfield="vol_and_avg"]]/td[2]
If you want different data, craft the XPath for the other data. Google's use of the data-snapfield attribue makes it easier to target a specific value. Some values, like vol_and_avg are paired and connected with a slash, thus the line to split() the data into two variables. Fields like market_cap won't need that.
