[Editor's note: see also xml_parse_into_struct().]
Very simple routine to convert an XML file into a PHP structure. $obj->xml contains the resulting
PHP structure. I would be interested if someone could suggest a cleaner method than the evals I am
using.
<?php
$filename = 'sample.xml';
$obj->tree = '$obj->xml';
$obj->xml = '';
function startElement($parser, $name, $attrs) {
global $obj;
// If var already defined, make array
eval('$test=isset('.$obj->tree.'->'.$name.');');
if ($test) {
eval('$tmp='.$obj->tree.'->'.$name.';');
eval('$arr=is_array('.$obj->tree.'->'.$name.');');
if (!$arr) {
eval('unset('.$obj->tree.'->'.$name.');');
eval($obj->tree.'->'.$name.'[0]=$tmp;');
$cnt = 1;
}
else {
eval('$cnt=count('.$obj->tree.'->'.$name.');');
}
$obj->tree .= '->'.$name."[$cnt]";
}
else {
$obj->tree .= '->'.$name;
}
if (count($attrs)) {
eval($obj->tree.'->attr=$attrs;');
}
}
function endElement($parser, $name) {
global $obj;
// Strip off last ->
for($a=strlen($obj->tree);$a>0;$a--) {
if (substr($obj->tree, $a, 2) == '->') {
$obj->tree = substr($obj->tree, 0, $a);
break;
}
}
}
function characterData($parser, $data) {
global $obj;
eval($obj->tree.'->data=\''.$data.'\';');
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!($fp = fopen($filename, "r"))) {
die("could not open XML input");
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
print_r($obj->xml);
return 0;
