DSL Functions

DSL stands for Domain Specific Language. In the case of Flow, the DSL is used to define simple functions that can be used to transform data. Most of those functions are initializing a new instance of a class under the hood since Flow is fully object-oriented. Please look at the examples below to get a better understanding of how to use the DSL functions.

EXTRACTOR

from_xml

source

/**
 *  In order to iterate only over <element> nodes use `from_xml($file)->withXMLNodePath('root/elements/element')`.
 *
 *  <root>
 *    <elements>
 *      <element></element>
 *      <element></element>
 *    <elements>
 *  </root>
 *
 *  XML Node Path does not support attributes and it's not xpath, it is just a sequence
 *  of node names separated with slash.
 *
 * @param Path|string $path
 * @param string $xml_node_path - @deprecated use `from_xml($file)->withXMLNodePath($xmlNodePath)` method instead
