Function that posted by "lz_speedy at web dot de" is nice, but have some problems with
attributes in open tags; this has an easy to use node-getter and example of using it:
<?php
function my_xml2array($__url)
{
$xml_values = array();
$contents = file_get_contents($__url);
$parser = xml_parser_create('');
if(!$parser)
return false;
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 array();
$xml_array = array();
$last_tag_ar =& $xml_array;
$parents = array();
$last_counter_in_tag = array(1=>0);
foreach ($xml_values as $data)
{
switch($data['type'])
{
case 'open':
$last_counter_in_tag[$data['level']+1] = 0;
$new_tag = array('name' => $data['tag']);
if(isset($data['attributes']))
$new_tag['attributes'] = $data['attributes'];
if(isset($data['value']) && trim($data['value']))
$new_tag['value'] = trim($data['value']);
$last_tag_ar[$last_counter_in_tag[$data['level']]] = $new_tag;
$parents[$data['level']] =& $last_tag_ar;
$last_tag_ar =& $last_tag_ar[$last_counter_in_tag[$data['level']]++];
break;
case 'complete':
$new_tag = array('name' => $data['tag']);
if(isset($data['attributes']))
$new_tag['attributes'] = $data['attributes'];
if(isset($data['value']) && trim($data['value']))
$new_tag['value'] = trim($data['value']);
$last_count = count($last_tag_ar)-1;
$last_tag_ar[$last_counter_in_tag[$data['level']]++] = $new_tag;
break;
case 'close':
$last_tag_ar =& $parents[$data['level']];
break;
default:
break;
};
}
return $xml_array;
}
//
// use this to get node of tree by path with '/' terminator
//
function get_value_by_path($__xml_tree, $__tag_path)
{
$tmp_arr =& $__xml_tree;
$tag_path = explode('/', $__tag_path);
foreach($tag_path as $tag_name)
{
$res = false;
foreach($tmp_arr as $key => $node)
{
if(is_int($key) && $node['name'] == $tag_name)
{
$tmp_arr = $node;
$res = true;
break;
}
}
if(!$res)
return false;
}
return $tmp_arr;
}
$arr = my_xml2array('test.xml');
print_r(get_value_by_path($arr, 'tag/sub_tag/sub_sub_tag'));
?>
