[PHP] Re: extracting data from XML file to PHP variable ..

Perhaps you should consider how you want your data structured. I'm not
sure what you're doing exactly, but consider the following file:
root
people
person
fullnameJohn Doe/fullname
/person
/people
person
fullnameKen Murrah/fullname
/person
person
fullnameJason Barnett/fullname
/person
/root
Do you see the problem? By assigning the character data to the element
tag each time, you would end up with $fullname = Jason Barnett. Would
you want this to be an array instead to grab all fullname tags?
Any help would be appreciated.
thanks.

function endElement($xml_parser, $name) {

}
function characterData($xml_parser, $data) {
if ($data != \n) {
$data = ereg_replace (\:, , $data);
print (piEncountered Character Data: /i$data\n);
}
}
function load_data($file) {
$fh = fopen($file, r) or die (pCOULD NOT OPEN FILE!);
$data = fread($fh, filesize($file));
return $data;
}
$xml_parser = xml_parser_create();
xml_set_element_handler ($xml_parser, startElement, endElement);
xml_set_character_data_handler($xml_parser, characterData);
xml_parse($xml_parser, load_data($file)) or die (pERROR PARSING XML!);
xml_parser_free($xml_parser) ;
If you're trying to keep track of attributes more directly you might try
using the Dom functions instead.

Yes, I am aware of the problem. However, for the very simple XML files
that I'm being asked to process, it's not an issue -- each file has, for
example, one and only one occurrence of fullname So, while I
realize that any solution I achieve for this project will have virtually
no portability to any future project, it would help me out of a terrible
mind in dealing with today's issue :-)
thanks.

Feel free to use it. http://www.reversefold.com/~papercrane/XML_Parser_Assoc/Assoc.phps I haven't used that class before, or else I probably would have suggested it instead of reinventing the wheel. On another note: what's the word on XML in PHP5? Do most of the XML implementations in PEAR plan to continue using a SAX based parser or switching to a new Dom/SimpleXML implementation? Just curious, I'd been thinking about a little something I might want to whip up. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
