Parsers 

The XML parser is a parser that was developed for TYPO3 6.2 and later versions. Based mainly on the PHP class SimpleXMLElement, it provides fast chart generation. However, the PHP code is complex. XML templates lack readability when iterative processing is required.

The new Fluid parser is entirely based on Fluid syntax and viewHelpers. Since all Fluid viewHelpers can be used (e.g. <f:for>, <f:if>, and <f:variable>) the Fluid parser results in simpler templates when iterative processing is required. It also provides simpler PHP code and makes it possible to use or develop other viewHelpers.
