This video covers importing XML and making it useable with the map function.
- [Instructor] Now we're going to take a look…at the data handler for xml.…And here's an xml file that I prepared earlier.…You can see we have each of the letters…of the alphabet A to zed…and a numeric value called frequency against each one.…You can copy what's on the screen…if you don't have access to the files.…And bear in mind, you don't need all 26 letters.…You can just copy, say five, if you like.…As long as you keep the structure exactly the same.…So you need to keep the xml declaration,…the enclosing data tags, the letter tags,…which contain an ID and the frequency tags…which contain a number.…
The data handler for xml works in much the same way…as the one for JSON.…You use d3.xml to load the file.…And my ones called data.xml…and then you have .get…within which we put function (error, data)…and we can shift that down a bit.…And I'm just gonna comment out these logs over here like so.…So the first thing we're going to do…is log our new data variable to the console.…
And you see it gives us something called a document.…
