Il y a, dans les commentaires de la doc PHP sur le xml_parser, une chouette fonction qui transforme un xml en array. Ce qui te permet de le parcourir facilement.
Je n'ai plus le nom de l'auteur pour lui rendre hommage, mais la voici:
static function xml2array($url, $get_attributes = 1, $priority = 'tag')
{
$contents = $url;
if (!function_exists('xml_parser_create'))
{
return array ();
}
$parser = xml_parser_create('');
xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8");
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($parser, trim($contents), $xml_values);
xml_parser_free($parser);
if (!$xml_values)
return; //Hmm...
$xml_array = array ();
$parents = array ();
$opened_tags = array ();
$arr = array ();
$current = & $xml_array;
$repeated_tag_index = array ();
foreach ($xml_values as $data)
{
unset ($attributes, $value);
extract($data);
$result = array ();
$attributes_data = array ();
if (isset ($value))
{
if ($priority == 'tag')
$result = $value;
else
$result['value'] = $value;
}
if (isset ($attributes) and $get_attributes)
{
foreach ($attributes as $attr => $val)
{
if ($priority == 'tag')
$attributes_data[$attr] = $val;
else
$result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr'
}
}
if ($type == "open")
{
$parent[$level -1] = & $current;
if (!is_array($current) or (!in_array($tag, array_keys($current))))
{
$current[$tag] = $result;
if ($attributes_data)
$current[$tag . '_attr'] = $attributes_data;
$repeated_tag_index[$tag . '_' . $level] = 1;
$current = & $current[$tag];
}
else
{
if (isset ($current[$tag][0]))
{
$current[$tag][$repeated_tag_index[$tag . '_' . $level]] = $result;
$repeated_tag_index[$tag . '_' . $level]++;
}
else
{
$current[$tag] = array (
$current[$tag],
$result
);
$repeated_tag_index[$tag . '_' . $level] = 2;
if (isset ($current[$tag . '_attr']))
{
$current[$tag]['0_attr'] = $current[$tag . '_attr'];
unset ($current[$tag . '_attr']);
}
}
$last_item_index = $repeated_tag_index[$tag . '_' . $level] - 1;
$current = & $current[$tag][$last_item_index];
}
}
elseif ($type == "complete")
{
if (!isset ($current[$tag]))
{
$current[$tag] = $result;
$repeated_tag_index[$tag . '_' . $level] = 1;
if ($priority == 'tag' and $attributes_data)
$current[$tag . '_attr'] = $attributes_data;
}
else
{
if (isset ($current[$tag][0]) and is_array($current[$tag]))
{
$current[$tag][$repeated_tag_index[$tag . '_' . $level]] = $result;
if ($priority == 'tag' and $get_attributes and $attributes_data)
{
$current[$tag][$repeated_tag_index[$tag . '_' . $level] . '_attr'] = $attributes_data;
}
$repeated_tag_index[$tag . '_' . $level]++;
}
else
{
$current[$tag] = array (
$current[$tag],
$result
);
$repeated_tag_index[$tag . '_' . $level] = 1;
if ($priority == 'tag' and $get_attributes)
{
if (isset ($current[$tag . '_attr']))
{
$current[$tag]['0_attr'] = $current[$tag . '_attr'];
unset ($current[$tag . '_attr']);
}
if ($attributes_data)
{
$current[$tag][$repeated_tag_index[$tag . '_' . $level] . '_attr'] = $attributes_data;
}
}
$repeated_tag_index[$tag . '_' . $level]++; //0 and 1 index is already taken
}
}
}
elseif ($type == 'close')
{
$current = & $parent[$level -1];
}
}
return ($xml_array);
}
