php - How to print the array that contains the tags and the data in this xml parser? -

<?php  class simple_parser  {     var $parser;     var $error_code;     var $error_string;     var $current_line;     var $current_column;     var $data = array();     var $datas = array();      function parse($data)     {         $this->parser = xml_parser_create('utf-8');         xml_set_object($this->parser, $this);         xml_parser_set_option($this->parser, xml_option_skip_white, 1);       xml_set_element_handler($this->parser, 'tag_open', 'tag_close');          xml_set_character_data_handler($this->parser, 'cdata');         if (!xml_parse($this->parser, $data))         {             $this->data = array();         $this->dat1 = array();             $this->error_code = xml_get_error_code($this->parser);             $this->error_string = xml_error_string($this->error_code);             $this->current_line = xml_get_current_line_number($this->parser);             $this->current_column = xml_get_current_column_number($this->parser);           }         else         {             $this->data = $this->data['child'];          }         xml_parser_free($this->parser);     }      function tag_open($parser, $tag, $attribs)     {         $this->data['child'][$tag][] = array('data' => '', 'attribs' => $attribs, 'child' => array());         $this->datas[] =& $this->data;            $this->data =& $this->data['child'][$tag][count($this->data['child'][$tag])-1];     echo(""); }      function cdata($parser, $cdata)     {         $this->data['data'] .= $cdata;       echo "$cdata";     }      function tag_close($parser, $tag)     {         $this->data =& $this->datas[count($this->datas)-1];     //echo "$this->datas[]";         array_pop($this->datas);     }  foreach ($this->data $i1 => $n1)              foreach ($n1 $i2 => $n2)                         foreach ($n2 $i3 => $n3)                 printf('$data[%d][%d][%d] = %d;<br>', $i1,$i2,$i3,$n3);?> } $file = "blr_hosp-1.kml";   if (!($fp = fopen($file, "r"))) {     die("could not open xml input"); } $data = fread($fp, filesize($file)); fclose($fp);  $xml_parser = new simple_parser; $xml_parser->parse($data);    ?> 

the foreach loop didn't work . how give output of xml file parsed , have stored array . want print tags , data in tag .

looking @ code, there looks few syntactical errors. correct following errors first, , let know if problem persists:

1. the line printf('$data[%d][%d][%d] = %d;<br>', $i1,$i2,$i3,$n3);?> has closing php tag @ end. (see ?>.)
2. i'm not sure 'foreach' loop correct you've placed it. reviewed braces ( {, }) few times make sure i'm right. looks foreach function not contained inside function. looks it's still inside class though, worse..

my suggestion place 'foreach' statement, after removing ?> characters, after '$xml_parser->parse($data);' command. (make sure edit $this replaced $xml_parser.)

i haven't reviewed rest of code errors--i may edit/update answer if i've suggested doesn't fix problem, or @ least figure out else wrong. :)
