This is a major step forward breaking compatibility with the past.
Under the hood there is a general reorganization to be PSR-0/4 compliant,
a general cleanup of the API for being consistent and allowing future clean APIs
growth, some notable additions like the ->filter() method to programmatically
filter the query results and ->html() to output the document as valid HTML 5 string.
Just because awesomenesses are never enough, ->query() supports CSS Selectors.
[+] New:
* ->html() is part of the family.
* ->filter() is part of the family.
* ->comment() is part of the family.
* ->setComment() is part of the family.
* ->addComment() is part of the family.
* ->size() is an alias of ->length().
* ->__invoke() is an alias of ->query().
* ->__toString() is an alias of ->xml().
* ->array() replaces ->asArray().
* ->addChild() replaces ->appendChild().
* ->addText() replaces ->appendText().
* ->addCdata() replaces ->appendCdata().
[~] Changed:
* ->query() supports CSS Selectors.
* fluidxml() has gained the super powers of fluidify().
* FluidXml->__construct() has gained the super powers of FluidXml::load().
* ->attr() can set attributes without value.
* ->setAttribute() can set attributes without value.
* ::load()/fluidify() can be ONLY used to load an XML file.
[-] Removed:
* ->asArray() has been removed superseded by ->array().
* ->appendText() has been removed superseded by ->addText().
* ->appendCdata() has been removed superseded by ->addCdata().
* ->appendChild() has been removed superseded by ->addChild().
* ->insertSiblingBefore() has been removed superseded by ->prependSibling().
* ->insertSiblingAfter() has been removed superseded by ->appendSibling().
[@] Internal:
* PSR-0/4 compliance.
* FluidXml.php is still there for people not using Composer/PSR-0/4 loaders.
* refactoring.
