What will you learn in this lecture?
In the previous video, we learned how to use attributes in XPath of this Selenium web driver elements identification course. In this video, we’ll have to learn how to use special operators in XPath.
How to Use Special Operators in XPath
So here, I have a few examples of everything we talked about. And what I quickly wanted to show are these last two right with these two slashes. It doesn’t matter what the tag is but we can skip everything and select the tags that we want.
So if I scroll down here to this table, we can see a cell. If we look at a cell here, it has a TD. Inside a TD lives some texts. Here check out another TD where some texts lives and another TD, table data. And the table data lives inside of a TR, which is a table row.
So if I wanted to select all of the table rows, anyone knows how I would do that? Well, so first I would put these double slashes right because we don’t care. We want to skip all of the parent structures and just get right down to the element that we want. And that would just be by putting TR here.
And if I hit enter, check it out! It selects every single table row. That’s what TR stands for a table row if I wanted the table body. I can do. I can do that! And now, it selects every single table data on this page.
You guys can see it selected every single TD tag if I wanted a specific one that’s a little different question. But for now, this is how you use these double forward slashes.
And now, if I wanted all of the attributes like class, I can do something like this. So now, it’s going to select every single class attribute on this page. If I hit enter, it selected them. If I wanted every single ID, check it out! See how it is selecting every single ID.
If I wanted every single ID, how about HREF, which is our link A trap, you guys see that! It is selecting every single link. So using this double slash in the @ symbol, and whatever attribute you want, you can select exactly, you can select all of the attributes.
And then obviously, we already went over this wildcard character just like anywhere else. It matches any element node. And then this matches any attribute node. So take a look at that! So any element node, that’s how I was doing this, right?
So if I hit enter now, what is it going to do? It’s going to select everything on the page. You guys see that? But then, if I wanted to do that and then just skip to a certain attribute, maybe I can do something like type. That’s not going to work to do like that. Type all the types.
And then if I do like this, it’s going to select every single attribute on the page. You guys see that? Select every single attribute on the page.
So you can use the star to skip through the HTML to get to the point where you want. Is that awesome wildcard character that we use everywhere else in all, even encoding?
And then finally, I also want to talk about the pipe which can allow us to select multiple elements. So for example, if you go back to this table, and I look at this table, I can select all of the TDs, right? Check it out all the table data.
And I can select all of the TRs table rows and table data or I can select all of the TDs and just the table headers. You guys see that? Instead of the table data, how about I just select the table rows, table rows and table headers. You guys see that? How it’s not only selected here. All the THs and all of the TRs are selected.
You guys see now how cool is that. So that’s what the pipe does.
