In that template, you would use the HTML option to generate an alphabetic enumeration, instead of a numeric one. The last remaining structure element is the NOTE element. Add the following template to handle that.

That brings us to the major reason for that special output tag we added early in the stylesheet:. That conversion is important, because most browsers do not recognize the empty tags. Here is a list of the affected tags:. The only remaining tags in the ARTICLE type are the inline tags-the ones that do not create a line break in the output, but instead are integrated into the stream of text they are part of. Inline elements are different from structure elements in that inline elements are part of the content of a tag.

If you think of an element as a node in a document tree, then each node has both content and structure. The content is composed of the text and inline tags it contains. The structure consists of the other elements structure elements under the tag. Note - The sample document described in this section is article3.

The result is stylizer3. Next, comment out the text-node normalization. It has served its purpose, and now you are to the point that you need to preserve important spaces:. Try the program without this modification to see the result. Here, you generate the appropriate inline tag using the name of the current element. Those curly braces cause the text inside the quotes to be processed as an XPath expression instead of being interpreted as a literal string.

Here, they cause the XPath name function to return the name of the current node. Curly braces are recognized anywhere that an attribute value template can occur. Attribute value templates are defined in section 7. For more information, see section 7. The last remaining element is the LINK tag. The easiest way to process that tag will be to set up a named template that we can drive with a parameter:. So this template gets executed only when you invoke it.

Note - Recall that an entry in quotes is interpreted as an expression unless it is further enclosed in single quotes. Without it, there would be no text in the generated HTML link. The not So this part of the template is interpreted when the target attribute is not specified.

Good work! As simple as it appears at first, it certainly provides a lot of opportunity for exploration. All you will have to do is to set up a stylesheet and use your browser. As lengthy as this section has been, it has only scratched the surface of XSLT's capabilities. Many additional possibilities await you in the XSLT specification. Here are a few things to look for:. The include statement simply inserts any definitions from the included file. The import statement lets you override definitions in the imported file with definitions in your own stylesheet.

Dynamically generate numbered sections, numbered elements, and numeric literals. XSLT provides three numbering modes:. Process an element multiple times, each time in a different "mode.

Variables are something like method parameters, in that they let you control a template's behavior. But they are not as valuable as you might think. You cannot pass a value from one template to another, or even from an enclosed part of a template to another part of the same template. These statements are true even for a "global" variable. You can change its value in a template, but the change applies only to that template. And when the expression used to define the global variable is evaluated, that evaluation takes place in the context of the structure's root node.

In other words, global variables are essentially runtime constants. Those constants can be useful for changing the behavior of a template, especially when coupled with include and import statements. But variables are not a general-purpose data-management mechanism. It is tempting to create a single template and set a variable for the destination of the link, rather than go to the trouble of setting up a parameterized template and calling it two different ways.

The idea is to set the variable to a default value say, the text of the LINK tag and then, if the target attribute exists, set the destination variable to the value of the target attribute. That would be a good idea-if it worked. But again, the issue is that variables are known only in the scope within which they are defined.

In other words, the value of such a variable, in this case, is null. All rights reserved. Hide TOC. Extensible Stylesheet Language Transformations. Defining a Simple Document Type Start by defining a very simple document type that can be used for writing articles. We will also allow for some inline tags that change the appearance of the text.

Note that This example uses a looping construct. It then will treat element after element in this node set. In addition, you could add a sorting statement as shown below in the code. You could, for instance, learn how to write custom rules for the same element sitting in different positions Depending on your XML structure and depending on whether you would like to create a nested TOC, this task can be fairly simple or fairly complex. You will find many examples online, e.

If you code manually each title with a specific attribute, the solution is simple, e. However, we plan to do this fully or semi-automatically. Since the titles you want to display are often somewhat "down" in the XML, you will have to learn how to write simple XPath expressions that will allow templates to be triggered.

For the moment, the documentation is the code below This example is slightly more complex than the base example. Titles sit underneath a chapter element and not each of these will have an id tag. The Xpath expression for filtering this is:.

The next example will deal with a text that doesn't give ID's to titles, i. It will need a more sophisticated Xpath expression to create a unique ID for each title. You must prefix each element name, and declare the namespace e. Be warned, the deficient XSLT engine of your navigator may not be able to display this. Transform in your editor, or use a server-side solution. Learn more in the XSLT for compound documents tutorial. The educational technology and digital learning wiki.

That implies that information within a ''content'' tag will not be displayed since we don't let the processor find templates by itself. The king's daughter followed it with her eyes as it sank, but the well was deep, so deep that the bottom could not be seen. Then she began to weep, and she wept and wept as if she could never be comforted. We count the position of the parent element chapter.
