This document provides an overview of FluentDOM, a jQuery-like library for traversing, manipulating, and selecting nodes in XML/HTML documents using XPath expressions. FluentDOM chains methods to allow concise queries and modifications, supports common DOM manipulation functions, and can be extended through custom node loaders and inheritance from the FluentDOMCore class.

4. About FluentDOM
● JQuery API
● DOMNodeList replacement
● Learning Project
● Test driven development
● Continous Integration
● Parser
● Tobias Schlitt
● Bastian Feder, Thomas Weinert

5. Differences To jQuery
● „Only“ Traversing, Manipulation and some Core
functions
● Xpath Expressions (not CSS Selectors)
● No method html() but xml()
● Callbacks have a $node parameter

6. Chaining
● Methods return objects

7. Chaining Sample
$fd = FluentDOM($html, 'html')
->find('/html/head/title')
->add('//h1')
->add('//h2');

8. Traversing
● find() ● children() ● first()
● add() ● closest() ● last()
● not() ● contents() ● prev()
● filter() ● parent() ● prevAll()
● has() ● parents() ● prevUntil()
● end() ● parentsUntil() ● next()
● andSelf() ● siblings() ● nextAll()
● nextUntil()

9. Xpath
● XML Path Language
● W3C Recommendation 16 November 1999
● Used by
● XSLT 1
● Xpointer
● More specific then CSS
● More powerful then CSS

10. Namespaces
● Xpath depends on namespaces
● Register your own namespaces prefixes
● Method: namespaces()
$title = FluentDOM($xml)
->namespaces(
array('project-atom' => 'http://www.w3.org/2005/Atom')
)
->evaluate(
'string(/project-atom:feed/project-atom:title)'
);

11. Interfaces
● IteratorAggregate
● Iterator
● RecursiveIterator
● Seekable
● Countable
● ArrayAccess (read only)

12. Functions
● Create FluentDOM object and load data
● FluentDOM
● FluentDOMStyle

13. Manipulation
● append() ● appendTo() ● xml()
● prepend() ● prependTo() ● text()
● before() ● insertAfter() ● attr()
● after() ● insertBefore() ● addClass()
● remove() ● wrap() ● removeClass()
● replaceAll() ● wrapAll() ● toggleClass()
● replaceWith() ● wrapInner()

14. Loaders
● Default Loaders
● DOMDocument, DOMNode
● XML (file and string)
● HTML (file and string)
● Additional Loaders
● SimpleXMLElement
● PDO
● JSON

15. Own Loaders
● Interface FluentDOMLoader
● load() returns DOMDocument or DOMNode

16. Extending FluentDOM
● FluentDOMCore
● spawn()
● push()
● unique()
● _applyContentsToNodes()

17. Future
● CSS Selectors
● ?
