BIG problem.

[Bob Bedford]

I've to manage quite very large XML files. I tough it was an SQL error, but
I've figured out the problem is somewhere else.

I've a big structure, with lot of datas and pictures encoded in every XML
files. Sometimes, I've error, and the script crashes.

Here is the code:

$xml_parser = xml_parser_crea te();
xml_set_element _handler($xml_p arser, "startEleme nt", "endElement ");
xml_set_charact er_data_handler ($xml_parser, "FDataHandler") ;

while ($data = fread($fp, 4096)) {
if (!xml_parse($xm l_parser, $data, feof($fp))) {
die(sprintf("XM L error: %s at line %d",
xml_error_strin g(xml_get_error _code($xml_pars er)),
xml_get_current _line_number($x ml_parser)));
rename($XMLPath .$file, $XMLPath.$failp ath.$file); //move file in error
path
$OK = false;
}
}
fclose($fp);
xml_parser_free ($xml_parser);

Now, this part of the code takes 4096 bytes and parse datas:
<datastart>
<data1>20040101 </data1>
<data2>20040220 </data2>
<data3>20040810 </data3>
</datastart>

Now, if the 4096 bytes are in the middle of the file, I get big problems. In
my case, the data2 is cutted somewhere in the middle
The script should only work when the </datastart> is reached, isn'it ??? but
how to do so ? The actual file is 5MB large, with lot of pictures in it.

Does you XML parser consider the case where elements are larger than 4096
bytes?

Actually not, because I don't know how to do so.
I do have this:

function endElement($par ser, $name)
{
switch($name){
case 'datastart': //commencer à enregistrer les données importantes pour
les véhicules
//save in DB. Get the error here sometimes
I didn't manage to check if the elements were larger than 4096 as I tough
the save in DB code was only executed when the closing tag was reached. If
I'm wrong, what's the solution ?
