foxshot | Capture web page screenshots using headless Firefox | Image Editing library

I like to keep track of Massachusetts lottery results (make sure the results are really random). I can bring up the page of results in any browser and copy-paste the lines of text, and run the text through a filter written in php or gawk to extract the numbers for each date. But I thought it would be nicer to automate the process using phantomJS to get the dates and numbers directly from the DOM.

I haven't been able to make this work because the elements containing the results do not appear to be in the DOM accessible through phantomJS. I don't know if I'm doing something wrong (I probably am) or if it's a problem with phantomJS (which I know is no longer maintained). But I also tried using the example of rendering a URL to a .png image directly from the Page Loading example in the quickstart, and the image came out as just background color with no text, so I'm thinking it's a problem with phantomJS. Or does that example need some extra code to wait for all the included scripts to complete?

Here is the example javascript with the URL in question and image filename hardwired:
