Q & A

XML: Visual QuickStart Guide, Examples

Here are some questions people have had while reading this book (with answers supplied when you click on each). If you have a question that you'd like to send me, please visit my Contact page.

Q: With XML Schema, why do some facets work with some simple types and some don't?

Q: Can you explain what an XML namespace is and how it's used?

Q: I know I should know this already since I know HTML well enough, but what exactly is a markup language?

Q: On page 5, you wrote, "An attribute's value must always be enclosed in either matching single or double quotation marks." But in your example, you used a file, not a value.

Q: In chapter 1, Writing XML, you point out that when nesting XML elements, each must be completely enclosed in another otherwise the XML document will not be considered well-formed. If an XML document is not well-formed, will it still work?

Q: I am enjoying your book but wanted to address something in your chapter on XPath Patterns and Expressions that needs clarification. On page 42, on your second tip, you say that by typing * (an asterisk) you select all the current node's children, but don’t you mean that 'element_name/*' will select all the current node’s children?
