Nice but cant get it to work!

Hello,

nice article but I dont really get it to work.
What i have now in my index.php

Code:

<? 
include("parser.php"); 

$template = new template(); 
$template->xml_path = ""; 
$template->xml_file="template.xml";
$template->load();

$template->add_elem("header","header"); 
$template->add_elem("body","body"); 
$template->add_elem("footer","footer");

$template->add_tags("title","This is the simpleXML test page"); 
$template->add_tags("logo","simpleXML is simple!"); 
$template->add_tags("column1","This is column one"); 
$template->add_tags("column2","This is column two"); 
$template->add_tags("column3","This is column three"); 
$template->add_tags("footer","this is the footer information");
 
echo $template->parse_elem();
?>

The parser.php and template.xml are just copy past from your tutorial and are in the same directory as index.php

Hope you can help me out.

thanxx

I am getting a few errors myself that I can't seem to figure out. I'm not sure if its the whitespace causing it or what but the xml file will not parse.

I created another xml file with a simple xml file and it works, but when I start adding html tags, etc I recieve errors like:

Code:

Warning: template2.xml:23: error: Input is not proper UTF-8, indicate encoding ! in d:\wamp\www\xml\index.php on line 3

Warning: in d:\wamp\www\xml\index.php on line 3

Warning: ^ in d:\wamp\www\xml\index.php on line 3

Warning: template2.xml:23: error: Bytes: 0x94 0x31 0x35 0x25 in d:\wamp\www\xml\index.php on line 3

Warning: in d:\wamp\www\xml\index.php on line 3

Warning: ^ in d:\wamp\www\xml\index.php on line 3

I'm using Php 5 RC3

what does your XML file look like?

do you have

<?xml version="1.0" encoding="UTF-8" ?>

at the top of your xml file?

The contents of my xml file:

Code:

<?xml version="1.0" encoding="UTF-8" ?>
<template>
		<header>
		<![CDATA[
			<html>
				<head>
					<title>Testing Xml</title>
					<style type="text/css">
						div {
						  border: 1px solid #333333;
						}
					</style>
				</head>
				<body>
					<div style="width:100px;">My Header</div>
					]]>
		</header>
		<content>
			<![CDATA[
			<div style="height:400px;">This is My Body</div>
			]]>
		</content>
		<footer>
			<![CDATA
				<div style="height:50px;">My Footer</div>
			</body>
		</html>
			]]>
		</footer>
</template>

And my php remains simple until I can isolated the problem

PHP Code:


		
			
<?php

 //error_reporting(E_ALL);

 $tpl = simplexml_load_file('template.xml');

 print_r($tpl);

 ?>

I am gonna take a stab at it again and see if it might be a whitespace issue, but as of yet I haven't found anything on simpleXml and whitespace.

Update:

Ok, I've gotten it to work to some extent. This will parse just fine:

Code:

<?xml version="1.0" encoding="UTF-8" ?>
<template>
		<header>
		<![CDATA[ 
					<html>
						<head>
							<title>Testing</title>
							</head>
							<body>
								<div style="text-align:center;"> Testing Whitepspace</div>
		]]>
		</header>
		<footer>
		<![CDATA[
			 <div>Footer</div>
			 </body>
			 </html>
			 ]]>
		</footer>
</template>

But assuming I copy and paste what the article states, the errors start pouring in, even though I've checked the syntax and everything seems to be ok, It still results in an error.

your article was a nice intro. to simplexml and template logic but I have to say the grammer and number of typos left a bad taste. devshed usually has pretty good articles and I would think they are trying to maintain some sort of standard. a thorough proof-read or two certainly wouldn't hurt especially when you are getting paid for your work.

Got the same errors

Could be a very usefull arcticle. But i got the same Errors,
This is is annoying.
The reason for the Errors are the strange quotes in
<td width=”15%”><!column1></td>

Also the include for the parser.php was missing.
As a beginner in php and xml this is confusing.
The remaing article is complete and helpfull.

Now that you know this fails, you can try using an XML declaration, as demonstrated in
Listing 5-2, but still not specify encoding. This will at least give libxml2 a chance to try to autodetect
the encoding used.
Listing 5-2. XML Document with French and XML Declaration but No Encoding
<?xml version="1.0"?>
<doc>
<élément>contenu d'élément</élément>
</doc>
This isn’t surprising—the parser encounters the same error. The parser detected the XML
declaration but detected it as UTF-8. So, the parser used the same encoding regardless of
whether you specified the XML declaration. If you saved the document in Listing 5-2 as a file
in UTF-16 format, the autodetection would have at least noticed this and tried loading it using
UTF-16 as the encoding.
For the last try to get this document to load properly, set the encoding attribute on the
XML declaration, as illustrated in Listing 5-3.
Listing 5-3. XML Document with French and Encoding Specified
<?xml version="1.0" encoding="ISO-8859-1"?>
<doc>
<élément>contenu d'élément</élément>
</doc>
This time it finally loads without an error. The encoding you needed in this case was
ISO-8859-1, which allows the use of the French characters within the document. If you now
instructed the parser to dump the document to the standard console, you might not expect
to see what it outputs:"
