How to use PHP functions to process XML data?
May 05, 2024 am 09:15 AM
Use PHPXML functions to process XML data: Parse XML data: simplexml_load_file() and simplexml_load_string() load XML files or strings. Access XML data: Use the properties and methods of the SimpleXML object to obtain element names, attribute values, and subelements. Modify XML data: add new elements and attributes using the addChild() and addAttribute() methods. Serialized XML data: The asXML() method converts a SimpleXML object into an XML string. Practical example: parse product feed XML, extract product information, transform and store it into a database.
