How do I validate XML

@jessjennJan 04.2004

How do I validate XML inside a string? Suppose I had the following:

[code] $x = ‘<fruits> <fruit> <type>apple</type> <color>red</color> </fruit> <fruit> <type>lemon</type> <color>green</color> </fruit> </fruits>’; [/code]

Is there a way to validate that? Thanks.

@jessjennauthorJan 04.2004 — #Thanks for the reply. I meant checking for errors. Being able to see if it's correctly structured:

Given the following XML data:

<i>
 </i>$x = '&lt;fruits&gt;
 &lt;fruit&gt;
 &lt;type&gt;apple&lt;/type&gt;
 &lt;color&gt;red&lt;/color&gt;
 &lt;/fruit&gt;
 &lt;fruit&gt;
 &lt;type&gt;lemon&lt;/type&gt;
 &lt;color&gt;green&lt;/color&gt;
 &lt;/fruit&gt;
 &lt;/fruits&gt;';

This is how I'm validating it:

[code=php]
  $success = xml_parse($parser, $x);
 
  if($success == 0) {
   $error_code = xml_get_error_code($parser);
   echo "error: ".xml_error_string($error_code)."<BR>";
   echo "row number: ".xml_get_current_line_number($parser)."<BR>";
   echo "column number: ".xml_get_current_column_number($parser)."<BR>";
  }
  else { // validated, now display values 
   foreach($fruits as $value){
   echo $value['type']."|".$value['color']."<br>";
   }
  }
 [/code]

Just want to make sure if this is how you validate it. Thanks!

@jessjennauthorJan 04.2004 — #Oh by the way, do you know off hand how I could add these characters < > ' " & inside the XML tags? I'm escaping them with their entities (> < etc.) and nothing. When they print out, they print out blank. Any ideas?

This is how I'm parsing it:

[code=php]<?
 $x = '<fruits>
 <fruit>
 <type>apple</type>
 <color>red</color>
 </fruit>
 <fruit>
 <type>lemon</type>
 <color>green</color>
 </fruit>
 </fruits>';
 
 
  #$x = '<fruits><fruit><type>apple</type><color>red</color></fruit><fruit><type>lemon</type><color>green</color></fruit></fruits>';
 
  $fruits = array();
  $current = '';
 
  // creating a resource parse
  $parser = xml_parser_create();
 
  xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, false);
  xml_set_element_handler($parser, 'startElement', 'endElement');
  xml_set_character_data_handler($parser, 'charHandler');
 
  function startElement(&$parser, $name, $attributes) {
   global $fruits, $current;
   if ($name == 'fruit') {
   $fruits[] = array();
   }
 
   if (in_array($name, array('type', 'color'))) {
   $fruits[count($fruits) - 1][$name] = '';
   $current = $name;
   }
  }
 
  function endElement(&$parser, $name) {
   //    empty
  }
 
  function charHandler(&$parser, $data) {
   global $fruits, $current;
   if (in_array($current, array('type', 'color')) ) {
   $fruits[count($fruits) - 1][$current] = $data;
   $current = '';
   }
  }
 
  $success = xml_parse($parser, $x);
  #var_dump($fruits); 
 
  if($success == 0) {
   $error_code = xml_get_error_code($parser);
   echo "error: ".xml_error_string($error_code)."<BR>";
   echo "row number: ".xml_get_current_line_number($parser)."<BR>";
   echo "column number: ".xml_get_current_column_number($parser)."<BR>";
  }
  else {
 
   foreach($fruits as $value){
   // insert sql statement: insert into...
   echo $value['type']."|".$value['color']."<br>";
   }
  }
 
 ?>[/code]
