To create efficient XSL files, it's first important to understand the XML data that you are trying to transform. In this video we will create an XML file that we will then later use in creating our first XSL file. Our XML file will describe the upcoming shows at our Cheek Chastain gallery. You see I have our shows.html file open here and we have a list of upcoming shows and the date, the author name, the show itself, thumbnail image, and the description of the show. What if this information is being generated automatically via XML. It will be nice if we can just take the XML data and place it on the page. So this is where we were headed towards, but the first thing what I am going to do is go ahead and create this XML file.
So we will go down to our next line and every XML document needs to have a parent tag. The same way the HTML files need to have an HTML tag that's a parent tag, your XML file must also have a parent tag. Now, that parent tag can be anything that you want it to be. In this case we are going to use a very descriptive tag and we are going to use galleryShows. So I am going to open up the galleryShows tag. Just like XHTML, if we open up a tag we will need to eventually close the tag. I am going to go ahead and hit Enter twice and type in a forward slash and Dreamweaver will go ahead and close that tag for me. So now we have an opening galleryShows tag and a closing galleryShows tag. So we are passing along information to whoever is reading this content that the content of this file XML file focuses on galleryShows.
So I will go back up after the galleryShows tag and I will create another empty line, and what I am going to do now is I am going to indent by hitting Tab you can wait until the very end and have Dreamweaver format this is for you, but I really prefer to do this as I am typing and I like keeping this sort of tab structure to let me know where I am within my document. So I am going to go ahead and type in showType lowercase S uppercase T. you will find that I usually use Camel Coding naming convention, so that I have a lowercase first name uppercase thereafter. We are going to go ahead and give this one an attribute, and I will add type equals and then in quotation marks Upcoming Shows. I will go ahead and close that, Enter twice, and then I will close the showType tag, and then I want to tighten up this one, empty line I have got here.
So we have several different types of galleryShows, we have the current show we upcoming shows we have past shows. So we are using another tag to identify what type of shows that is that we were working with. Now inside the Upcoming Shows tag, I am going to go ahead and place my courser in there. I will hit tab again so that it intends one more time. It's time to start describing the actual shows themselves. So I will open up another tag, and this time I am going to use the Show tag. Now you will notice that Dreamweaver is giving me code handling that says hey, do you want to use a show tag. You will also notice that even though it didn't do it prior to this, showType now lists as well. Dreamweaver keep tracks of the tags you have been typing and it beings to add them to a temporary tag library.
If you want to add these tags permanently, you can go ahead and import your XML schema into your tag libraries. If you like a little information how to do that, we will cover that that in Chapter 1 Workflow movie. So we will finish out our show tag and we are going to give this show a name and the name of the show is going to be Relevant Works. That's our first show. After that we are also going to give this show a date, and that's because we loaded up the schema earlier to actually prompting us for both date and name when we add attributes to the show tag. So for date I am going to type in 5.26.
I will close that and hit Enter twice and then I will close my show tag. So you can see we are just building a really basic structure that we have our galleryShows tag our inner show type and then we were working with individual shows inside of that. Each show has information that we need to pass along as well. The first thing that we will pass along -- and I will hit tab inside my show tag -- will be the artists themselves. So we will say artist name equals and in this case it will be Josh Cavalier, close that.
Now I could close the Artist tag at this point, but I actually have the information about the artist. We are going to pass in paintings that are featured in this show, and that's going to pass as part of the artist information. So I will use the painting tag directly inside the artist and I will pass in a name to it and the first name is going be This Caravel, and if you want you can make a peer on painting names, that's part of fun I am doing this. I will close that and I am also going to close the painting tag. So tags don't necessarily have to have anything inside of them. Now, there is nothing wrong with copying and pasting other than having to type this over again. I am going to copy that paste it down to the next line, and the next painting is actually going to be Something in the Lawn. I will go to the next line and paste that in again. Our next tag will be In the Temple. We will do one more painting. Each artist has four paintings and our next one will be Typography.
Now remember we still have an open artist tag and sometimes it's hard to remember when you still have an open tag and that's one of the reasons why I like to get into a habit of opening a tag, going ahead and hitting Enter twice and closing the tag, and then filling in the contents. So we didn't do that this time but we should remember that in future. So we will go ahead and close our artist tag. Now we are not totally done with our first show. Remember that we also had an image that goes with this and a description. So I am going to go to the next line, use the image tag, and from our image -- I am going to give it a title and it will be the Relevant Works. Now it seems odd to have maybe a title for the image, but we are actually going to use this for alt text later. Next I am going to type in URL and URL is going to be ../_images/josh_fav_thumb.jpg, close that and then we will close our image tag.
It may actually try to close the show tag on you there, but go ahead to make sure it closes the image tab, because that is the open tag at the moment. We did not open up a new show tag, so it may have something to do with how we intended in our code. The last thing we needed to add is a description. So I am going to open up one more and this will be a description tag, and then instead of passing along the descriptions attribute, it's a really long little string, so we will go ahead and pass it along inside the description tags, and I am going to type in Local artist Josh Cavalier returns for a three week showing of his most relevant works. There will be a slide presentation prior to the reception showcasing Josh's current works in progress. As soon as I type that in, I will go ahead and close my description tag and I want to save the file.
Now we haven't saved this yet, so those of you are following we are going to navigate in our class file and find the Chapter 7 Starting Files. So we haven't defined that site yet, go ahead and define it. I am going to go in the Starting Files and there is a folder called XML. I am going to select the XML folder and I am going to name this file upcoming.xml. So now we have saved it as upcoming.xml. Now we are almost done with it but there is actually three additional shows that need to be described. So what I am going to do is I am going to jump forward a little bit and I will show you the finished version of this file. You are free at that point of pause the movie and then finished typing all the three shows save the file, and then in our next movie we will look at using something known as Character Data Statement to make sure our descriptions parts properly.
I will be displaying the finished XML file here in just a moment. Feel free to pause the movie and type in what you see on the screen or if you have the Example Files you can pull this out of the _text folder, which is where I will be grabbing it from. Here we have added the show for Joe Williamson named Point Freeze and you will need to add everything between the opening show tag on line 14 and the closing show tag on line 23. Our next show is from Jennifer Loman. The show's name is Expandscapes and you are going to need to add the code from lines 24 with the opening show tag to line 33 with the closing show tag.
Our final show will be Chris Mattia's and the show name is Blistery. You want to add the code from line 34, the opening show tag to the closing show tag on line 43. That should complete our XML file. So be sure once you have added that code to go ahead and save that file and that will move us on to our next lesson where we look at formatting the descriptions data with using CDATA state.
