Hello all,

I am working on making a small CMS for a personal project.The cms will use a simple xml document with the following format.

<?xml version="1.0"?>

<root>
<page><id>1</id>
    <title>Sample Date</title>
    <description>This is the description</description>
    <content>This is some content</content>
</page>

<page> <id>2</id>
    <title>Sample Content 2</title>
    <description>This is the description</description>
    <content>This is some content</content>
</page>

</root>

At this point, I can get information, but I am unable to choose which piece I want. My thought was to find the node from the start tag, add a marker and send that to the actual node.

Somehow, I think this logic is flawed. I would like to be able to search the document by id, and then work on displaying the content contained under that id.

PHP Code:

$file = "database.xml";

function defaultHandler($parser, $text){
echo $text .'default';

}
function startElement($parser, $name, $text){
    $val = '2';

    $name = strtolower($name);
    if ($name == 'id')
    {
    
    $x = "1";
    print $x;
    return $x;
    
    }
     else
       $x = "0";
       print $x;
       return $x;
       
       
}


         

function text ($parser, $text, $x){
print $x;
 if(preg_match("/\S/", $text)) {
     
 }
}


function endElement($parser, $name){

}


$xml_parser_object = xml_parser_create();
xml_set_element_handler($xml_parser_object, "startElement", "endElement");
xml_set_character_data_handler($xml_parser_object, "text");
xml_set_default_handler($xml_parser_object, "defaultHandler");

if (!$handle = fopen($file, "r")) {
    die("Error.");
}
while ($xml_data = fread($handle, 1024)) {
    if (!xml_parse($xml_parser_object, $xml_data, feof($handle))){
        die(sprintf("Error %s on line %d", 
                xml_error_string(xml_get_error_code($xml_parser_object)), xml_get_current_line_number($xml_parser_object)));
    }
}

xml_parser_free($xml_parser_object);
fclose($handle); 


Why don't you just use simplexml?

Construct your XML data like this:

<?xml version="1.0"?>
<root>
    <page id="1">
        <title>Sample Date</title>
        <description>This is the description</description>
        <content>This is some content</content>
    </page>
    <page id="2">
        <title>Sample Content 2</title>
        <description>This is the description</description>
        <content>This is some content</content>
    </page>
</root>

And your php is simple with a little function to search data:

PHP Code:

<?php
    
  if (!$xml_content = file_get_contents('xml.xml')) die('Unable to get XML file');
  
  if ($xml = simplexml_load_string($xml_content))
  {
    echo get_xml_node_value_from_attribute('title', 'id', '2', $xml);
  }
  
  // Define locate function
  function get_xml_node_value_from_attribute($node, $attribute, $value, $xml)
  {
    $string = '';
    
    foreach ($xml AS $element)
    {
      if ($element[$attribute] == $value)
      {
        $string .= (string)$element->$node;
      }
    }
    
    return $string;
  }

Never mind, I figured out what was confusing me. I feel like such an idiot LOL. Thanks.
