How
to do XML parsing with PHP
Functions
to do XML parsing area available in PHP and you can use them to parse
XML data. You can split up the task of using the parser on an XML file
into three major tasks.
_______________________________________________
One
is to handle the starting tags, the second is to handle the ending tags,
and the third and final one is to handle the character data that is
found in the XML file. You can write different functions for these three
purposes and then use them along with the parser to handle the XML file.
You can
use the 'xml_parser_create();' command to create an instance of the
XML parser. Set the handlers 'xml_set_element_handler();'
and the
'xml_set_character_data_handler();' to handle the starting tags, ending
tags and the character data that is found between the tags.
After you
set the handlers you can use the parser and parse the XML data and throw
any error if you encounter any error while parsing. Displaying the error
with the line number helps you to debug. After parsing you have to free
up the memory used by the parser and close the XML file used.
