Learn parsing XML using PHP

You can parse XML data from an XML file using PHP if you use a parser. In using the parser you should know how to handle the starting tags that are found in the XML file and ways to handle the ending tags in the XML file. It is better to create functions to handle both of these.

Create separate functions to handle the starting tags and the ending tags. Also write a function that will handle the data that is encountered between the starting and the ending tags. If you can do this then it is easy to work with the parser using PHP.

While writing the actual code you have to use xml_parser_create(); to create a parser. You can create xml_set_element_handler(); to handle the starting and the end tags. The 'xml_set_character_data_handler();' can be used to handle the character data that is found between the tags. You have to set the handlers first and then open the XML file to read and parse. Once this task is over you should not forget to free up the memory taken by the parser and then close the XML used.
