To explain, all the H2 headers you are looking for are within the div element that contains the class attribute of entry-content. Therefore, seprating the h2 with a space on the div container according to the CSS SELECTOR syntax, will return all h2 within that specified div.
The Dump befofore the entire CsQueryOnUrl simply takes all those possible results, or an array, and literally "Dumps" them into the rows below. If you want the Dump to span across the columns, or horizontally, you can use the boolean value for the transpose variable in the function like so:
Here's what it looks like in Excel with the results from both functions side-by-side.
Let me know if this isn't what you're looking for. But that's basically what I understood as the data you're looking for.
ADDITION TO POST:
Here's a simple guide for CSS SELECTOR elements and how they work on the pages: w3schools.com - CSS Selectors
Definitely try their tester too, you can click on specific elements and it will highlight them in action as you click. It's on that same link, but here's the direct link to their little web app: w3schools.com - CSS SELECT it Yourself
Also, here's one for XPath: w3schools.com - XPath Syntax
XPath is sometimes needed for cases where css syntax will not achieve the desired output. The good thing about XPath is that it has those additional features where you CAN search by contains(text() as you originally had planned.
This above code returns a Dump of all the h2text that contains the text "affordable" no matter the case. So from this, we can come up with a count now. We'll simply place the count like you originally had it and get rid of the dump...
No problem. I think it took me roughly 3 hours, while working on other projects. It's funny though, when I tried to figure out the syntax myself a few months ago I couldn't do it. And I just gave up.
But anyway, in-case anyone needs to filter the dumped array that we have- that is, to only show the parameter in question, which in this case is "affordable"- we can run a RegexpFind(\baffordable\b) between the Dump & XPath like so:
Now we Have our Dump of the "affordable" keyword in its original format!
Just to keep this thread goin, there's a lot of interesting functions SeoTools has, especially when combined with Excel.
So now let's run this excel built-in PROPER case function on the data we have (Excel 2007 and up):
We'll run this in a separate range. You can however add-on top of the existing code and ideally end up with one single column, but imo I think it's always good to keep copies of the data you're working on. Excel can be nightmarish if you aren't prepared.
Edit: For some reason, PROPER didn't modify the "S" in "That'S""
