2. XML Bootcamp: What and How What is XML? Why XML? ColdFusion and XML Summary Links

3. What is XML? eXtensible Markup Language Universally readable by computers and humans (at least in theory!) Focuses on the rules for describing content No restrictions on content (except...) Basic concepts  Elements  Attributes  Entities  sections

4. What is XML? (continued) Basic rules  All tags must be closed ...except! Self-closing tags  No forbidden characters ● Use “entities” or CDATA ● < is < ● > is > ● & is & ● ● Other characters are in the references links at the end Documents must have a root element that wraps everything else in the document A valid xml document can be as little as:  somecontent

6. Why XML? Structured Parsable  Can be converted into objects  In the CF world: structures and arrays Universal  Java, CF,.NET, PHP, ActionScript  RSS, AJAX, Microsoft Office, SQL Server  ANYTHING that has a need for structured data Simple for Beginnners Extremely flexible and powerful for advanced users Portable

7. Why XML? (continued) Searchable  XPath (demo tonight)  XQuery (no demo tonight) ● Not supported by CF yet A mix of very familiar concepts  Directories on disk  Database tables  HTML!! (yeah, I thought that looked familiar!) Stylable  XLT and XSLT ● Perhaps a brief demo tonight Extensions VERY POWERFUL and yet very simple

8. ColdFusion and XML Built-in Functions:  xmlParse(“xmlString”)  xmlSearch(“XPath”,xmlObject)  isXml(“xmlString”)  isXmlObj(variable) Elements are Arrays Attributes are Structs Live Demo: code and examples
