How To Parse XML without XSLT_CREATE

[admin]

<?php

$file = "guestbook.xml";

# function to handle the beginning tags
function tagBegin ($parser, $element, $attributes) {
$element = strtolower($element);
global $elem;
switch ($element) {
case 'entry':
$elem = "entry";
echo "\n <div class=\"entry\">";
break;
case 'title':
$elem = "title";
echo "<p class=\"title\">";
break;
case 'message':
$elem = "message";
echo "<p>";
break;
case 'name':
$elem = "name";
echo "<p class=\"footer\">Posted by ";
break;
case 'time':
$elem = "time";
echo " on ";
break;
default:
$elem = "default";
break;
}
}

# function to handle the data of each element
function cdataEater ($parser, $cdata) {
global $elem;
switch ($elem) {
case 'time':
if (is_numeric($cdata)) {
echo date("F d, Y h:i a", $cdata);
}
break;
default:
#split words that are more than 50 characters long
$message = explode(" ", $cdata);
$splitmessage = "";
foreach ($message as $word) {
$splitmessage .= wordwrap($word, 40, " ", 1)." ";
}
$message = $splitmessage;
echo $message;
break;
}
}

# function to handle the ending tags
function tagEnd ($parser, $element) {
$element = strtolower($element);
switch($element) {
case 'entry':
echo " </div>\n";
break;
case 'title':
echo "</p>";
break;
case 'message':
echo "</p>";
break;
case 'name':
break;
case 'time':
echo "</p>\n";
break;
}
}

# create the parser and set the handling functions.
$parser = xml_parser_create();
xml_set_element_handler ($parser, 'tagBegin', 'tagEnd');
xml_set_character_data_handler ($parser, 'cdataEater');

# read the file.
$fp = @fopen ($file, 'r') or die ("Could not open guestbook file \"$file\" for reading");
while ($data = fread ($fp, filesize($file))) {
if (!xml_parse ($parser, $data, feof($fp))) {
echo 'XML parsing error: '
.@xml_error_string(@xml_get_error_code($xml_parser))
.' at line '.@xml_get_current_line_number($xml_parser).'.';
}
}

# free up the parser.
xml_parser_free($parser);
?>

And the guestbook.xml file would look like this:
<guestbook>
-
<entry>
<title>Confusion?</title>
-
<message>
Would it be classed as confusing readers if they were to read the XML raw?

Example just below...

You have <message></message></message> in the XML.
</message>
<name>Bon Bon</name>
<time>1076637076</time>
</entry>
-
<entry>
<title>Test</title>
<message></message></message>
<name>Bon Bon</name>
<time>1076636927</time>
</entry>

Also what would be good is if you recorded peoples IP addresses so that you know that wannabies like loys, whoever that is, are not me.

Another suggestion, try including options to allow people to format the post with bold and etc but make sure that only attributes that make sense in the XML are added.

Nice! The flood restriction is a bit annoying though, maybe 15 seconds would be better?
