I am attempting to use PHP’s SAX parser to process an XML document, but getting the error:
Warning: xml_parse(): Unable to call handler startElementHandler() in /mnt/drbd/home/mywebsite.com/test.php
Warning: xml_parse(): Unable to call handler characterDataHandler() in /mnt/drbd/home/mywebsite.com/test.php
Warning: xml_parse(): Unable to call handler endElementHandler() in /mnt/drbd/home/mywebsite.com/test.php
These three lines are repeated for each line of my XML.
I am using PHP version 4.4.0 and when I run phpinfo I see:
XML Support active
XML Namespace Support active
EXPAT Version 1.95.6
XSLT support enabled
Backend Sablotron
Sablotron Version 1.0
Any idea why I am getting this error? Am I missing something on my server?
This is my test.php code:
$xml_parser = xml_parser_create();
//set callback functions
xml_set_element_handler($xml_parser, "startElementHandler", "endElementHandler");
xml_set_character_data_handler($xml_parser, "characterDataHandler");
//read XML file
if (!($fp = fopen("fox.xml", "r"))) {die("File error");}
//parse XML
while ($data = fread($fp, 4096)) {
//error handler
if (!xml_parse($xml_parser, $data, feof($fp))) {
die("XML Parser error: " . xml_error_string(xml_get_error_code($xml_parser)));
}
}
xml_parser_free($xml_parser);
//run this function when start tag is parsed
function startElementHandler ($parser, $name, $attributes) {
echo "Found opening tag of element: <b>$name</b><br>";
//process attributes
while (list ($key, $value) = each ($attributes)) {
echo "found attribute: <b>$key = $value</b><br>";
}
}
//run this function when end tag is parsed
function endElementHandler ($parser, $name) {
echo "Found closing tag of element: <b>$name</b><br>";
}
//run when cdata is parsed
function characterDataHandler ($parser, $cdata) {
echo "found CDATA: <i>$cdata</i><br>";
}
