Here is a simple set of tables that give the name and location of each XML file included in the collection of example files for XML for the World Wide Web: Visual QuickStart Guide. Instead of just giving you the snippets of code that are shown in the illustrations (which would be of limited use), I have fleshed out those examples and commented them (within the files themselves) so that you can get more out of them, tinker with them, test them, and ultimately, see how they work. I hope they are worthwhile. Comments are welcome.

You can download all the examples for Macintosh or for Windows/Unix.

If you have any questions, suggestions, or corrections, please contact me.

Chapter 3, Defining Elements and Attributes in a DTD

The files in this section are in the dtd_defining folder. You'll note that these files contain more than what is shown in the illustrations. I have fleshed out these examples so that you can really test them against an XML Validator. In fact, I heartily recommend doing so. Copy them to your server, play around with them, and then study the error messages that XML Validator gives you! I hope you find them useful.

Part 3: XML Schema and Namespaces

Note that the examples in these chapters are almost all based on the end_species.xsd and end_species.xml files, with minor changes, according to the topic in question. More importantly, I have gone to the trouble (over two excrutiating months) to flesh out the examples so that you can really play around with them, send them to XSV for validation and see how they work. Please do copy them to your own site, and then test them and retest them and analyze them. Pay special attention to the comments within the documents, in which I explain which parts are in question and what is going on with them. I hope you find them useful. Let me know.

Chapter 8, Using Namespaces in XML

The files in this section are in the namespaces folder. Note that no Schema files are given for the latter examples...we don't get to validating XML files that use namespaces until the next chapter. If there is sufficient interest, I could work out the appropriate schema files. Let me know.

Page Section Code

132 Importing Components import.xsd, rivers_import.xsd (not rivers.xsd), and then import.xml as an instance. Note the errata resolved in the notes here.


Part 4: XSLT and XPath

Note that the examples in these chapters are almost all based on the tigers_rhinos.xml and tigers_complete.xsl files. The XSLT files gradually build up to the tigers_complete.xsl file, with minor changes depending on the topic in question. For maximum effect, you'll also need the tiger.jpg and rhino.jpg images.

Chapter 10, XSLT

The files in this section are in the xslt folder. Note that all of these XSLT files transform the very same tigers_rhinos.xml file. The HTML files shown were generated by transforming the tigers_rhinos.xml file with the given XSLT file, using Saxon.

Page Section Code
136-137 Transforming XML with XSLT Figure 10.1: tigers_rhinos.xml
Figure 10.3: tigers_complete.xsl
138 Beginning an XSLT Style Sheet begin.xsl
139 Creating the Root Template root.xsl, root.xml
140-141 Outputting HTML Code html.xsl, html.html
142-143 Outputting a Node's Content node.xsl, node.html
144-145 Creating and Applying Template Rules templates.xsl, templates.html
146-147 Batch-Processing Nodes for-each.xsl, for-each.html
148 Processing Nodes Conditionally if.xsl, if.html
149 Adding Additional Choices choose.xsl, choose.html
150 Sorting Nodes Before Processing sort.xsl, sort.html
151 Generating Attributes attributes.xsl, attributes.html

Chapter 11, XPath: Patterns and Expressions

The files in this section are in the xpath folder. Note that many of the examples in this chapter use the same files as examples from the XSLT chapter. That's because we've already seen some of these patterns and expressions, but they are explained and highlighted here. Note also that the HTML files shown were generated by transforming the tigers_rhinos.xml file with the given XSLT file, using Saxon.

Page Section Code
154 Determining the Current Node same as sort.xsl, sort.html (from page 150 in Chapter 10)
155 Referring to the Current Node same as sort.xsl, sort.html (from page 150 in Chapter 10)
156 Selecting a Node's Children same as sort.xsl, sort.html (from page 150 in Chapter 10)
157 Selecting a Node's Parent or Siblings siblings.xsl, siblings.html
158 Selecting All of the Descendants descend.xsl, descend.html
159 Disregarding the Current Node disregardnode.xsl, disregardnode.html
160 Selecting a Node's Attributes same as siblings.xsl, siblings.html
161 Selecting Subsets same as siblings.xsl, siblings.html

Chapter 12, Test Expressions and Functions

The files in this section are in the expressions folder. Note that the first seven HTML files (pages 164-170) shown were generated by transforming the tigers_rhinos.xml file with the given XSLT file, using Saxon. The examples from pages 171-173 are generated by transforming the tigers_rhinos_noinitials.xml file with the given XSLT file, also using Saxon. Also note that up until page 169, for simplicity's sake, I did not include the picture template. It appears again from page 170 on. You can find more information about the picture template in the Generating Attributes section on page 151 in Chapter 10.

Page Section Code
164 Comparing Two Values same as choose.xsl, choose.html (from page 149, Chapter 10)
165 Testing the Position position.xsl, position.html
166 Subtotaling Values sum.xsl, sum.html
167 Counting Nodes count.xsl, count.html
168 Multiplying, Dividing, Adding, Subtracting multiply.xsl, multiply.html
169 Formatting Numbers formatnumber.xsl, formatnumber.html
170 Rounding Numbers ceiling.xsl, ceiling.html (again, notice that the picture template from page 151 is used here--for the first time in this chapter)
171-172 Extracting Substrings

Figure 12.19: tigers_rhinos_noinitials.xml (All the other XSLT files refer to the tigers_rhinos.xml file.)

Figures 12.20 and 12.21: substring.xsl, substring.html

Figures 12.22 and 12.23: substring_after.xsl, substring_after.html

173 Capitalizing Strings translate.xsl, translate.html


Part 5: Cascading Style Sheets

Note that the examples in these chapters are almost all based on the panthers.xml and panthersblurb.xml files. I have created a separate xml file for each example that references the proper CSS stylesheet, but unless noted, all the XML files are otherwise identical. The CSS files build on each other gradually.

Chapter 13, Setting up CSS

The files in this section are in the css folder.

Page Section Code
177 Setting up CSS

Figure 13.1: panthers.xml
Figure 13.2: panthers.html

178 CSS with XML vs. CSS with HTML Figure 13.3: panthers.xml
Figure 13.4: panthers.html
180-181 Specifying Where Styles Are To Be Applied

Figure 13.6: where1.css
Figure 13.7: where1.xml

Figure 13.7: where2.css
Figure 13.8: where2.xml

182-183 Creating an External Style Sheet external.css
184-185 Calling a Style Sheet for an XML Document

Figure 13.11: call_stylesheet.xml (end_species.css)

Figure 13.12: call_stylesheet_xml.xsl is the document shown. It is used to transform panthers.xml into call_stylesheet_xml.xml which calls end_species.css for formatting information.

186 Calling a Style Sheet for an HTML Document callstyles_html.xsl, (tigers_rhinos.xml, callstyles_html.html, callstyles.css)
187 Using Internal Style Sheets callstyles_html_internal.xsl
188 Applying Styles Locally local_styles.xsl (local_styles.html)

Chapter 14, Layout with CSS

The files in this section are in the css_layout folder. The XML files formatted by the CSS examples on pages 190-197 are identical to panthers.xml, except for the call to the individual stylesheet. The XML files used from pages 198-205 are identical to panthersblurb.xml--except for the call to the individual stylesheet--(which only differs from panthers.xml in the addition of an extra sidebar (blurb) paragraph.) Finally, the examples in the last two sections (pages 206-9) are identical to the pantherlist.xml file--again, except for the call to the individual stylesheet.

Page Section Code
190 Defining Elements as Block-Level or Inline

block.css (block.xml)

191 Hiding Elements Completely hide.css (hide.xml)
192 Offsetting Elements In the Natural Flow relative.css (relative.xml)

200 Changing the Foreground Color foreground.css (foreground.xml)
201 Changing the Background background.css (background.xml)
202 Positioning Elements in 3D zindex.css (zindex.xml)
203 Aligning Elements Vertically verticalalign.css (verticalalign.xml)
204 Determining Where Overflow Should Go overflow.css (overflow.xml)
205 Clipping an Element clip.css (clip.xml)
206-207 Setting List Properties lists.css (pantherlist.xml)
208 Specifying Page Breaks pagebreak.css (pagebreak.xml)

Chapter 15, Formatting Text with CSS

The files in this section are in the css_text folder. All of the XML files are identical to panthers_layout.xml, except for the call to the individual stylesheet. Indeed panthers_layout.xml is simply the same panthersblurb.xml file we saw in the last chapter with a call to the layout.css stylesheet which includes all the layout information we added in Chapter 14. Note also that you'll need the embedded font files for all the examples from page 211 on, and that the embedded fonts will only be visible in IE5 for Windows.

Page Section Code
210 Choosing a Font Family

font-family.css (font-family.xml)

211 Embedding Fonts on a Page embedfonts.css (embedfonts.xml)
212 Creating Italics italic.css (italic.xml)

216 Setting All Font Values at Once font.css (font.xml)
217 Setting the Text Color color.css (color.xml)
218 Changing the Text¹s Background background.css (background.xml)
219 Controlling Spacing spacing.css (spacing.xml)
220 Aligning Text text-align.css (text-align.xml)
221 Underlining Text underline.css (underline.xml)
222 Changing the Text Case transform.css (transform.xml)


Part 6: XLink and XPointer

Chapter 16, XLink and XPointer

Since none of the examples in this chapter can really be tested yet (except for well-formedness, but that's pretty boring), I haven't taken the trouble of posting the code. If you really want a copy of it, just let me know. I'd be happy to give it to you (or post it, if a lot of you want it). Once browsers can deal with XLink and XPointer, I will make these examples more real and then post the code so you can see how they work for yourselves. Comments?
