[SOLVED] XML parsing

[saipkjai]

hi

 

  I was trying to parse a segment of XML into plan html like the following

 

<author>

  <name>John Doe</name>

  <email>johndoe@example.com</email>

</author>

 

TO

 

<a href="johndoe@example.come">John Doe</a>

 

 

and I have the following code for the parsing

 

<?php
$file = $_POST['url'];

$authorItem = array();
$authorList = "";

function startElement($parser, $name, $attrs)
{

global $authorList;

switch($name){
            case "TITLE":
			echo "<h2>";
			break;
            case "AUTHOR":
			$authorList .= "*$name";
			break;
            case "NAME":
			$authorList .= "*$name";
			break;
            case "EMAIL":
			$authorList .= "*$name";
			break;
}
}

function endElement($parser, $name)
{
global $authorList;
global $authorItem;

switch($name){
            case "TITLE":
			echo "</h2>";
			break;
            case "AUTHOR":

			if($authorList == "*AUTHOR*NAME*EMAIL"){

				printf("<a href=mailto:%s>%s</a>", array_pop($authorItem), array_pop($authorItem));
				$authorList = "";
			}
			elseif($authorList == "*AUTHOR*NAME"){
				printf("<p>%s</p>", array_pop($authorItem));
				$authorList = "";
			}
			break;
}
}

function characterData($parser, $data)
{
global $authorList;
global $authorItem;

    
if($authorList == "*AUTHOR*NAME*EMAIL"){
	array_push($authorItem, $data);

	for($i = 0; $i < count($authorItem); $i++){
		echo "$i" . "$authorItem[$i]" . "\n";
	}

}
    elseif($authorList == "*AUTHOR*NAME"){
	array_push($authorItem, $data);

}
else{
	echo $data;
}
}

$xml_parser = xml_parser_create();

xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
$fp = fopen($file, "r");

while ($data = fread($fp, 4096)) {
xml_parse($xml_parser, $data, feof($fp));
}
xml_parser_free($xml_parser);
?> 

 

The problem that I'm facing now is, somehow, the array authorItem will store John Doe at [0], then blank at [1] and the email at [2]. Is there some step I got it wrong while parsing occur?

Properly formatted xml file named name_email.xml:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0"
xmlns:content="http://purl.org/rss/1.0/modules/content/">
	<content>
		<author>
		  <name>John Doe</name>
		  <email>johndoe@example.com</email>
		</author>
	</content>
</rss>

 

php5 script:

 

<?php
$feed = simplexml_load_file('name_email.xml');
$name = $feed->content->author->name;
$email = $feed->content->author->email;
echo "<a href='$email'>$name</a>";
?>

 

That's as easy as it gets.

Thx for the reply!!

 

I was surprise that it was this simple. But then I have another question

 

Firstly, the version of XML file that I'm working with is version 1.0, does this method works with version 1.0?

Secondly, the XML file that I'm working with has many many other entry, some of them have only <author><name></name></author>, some of the other have email tag between it as well, how can I use the simple method that you suggest for those entry?

Thridly, some of the tag like <link /> does not have open and close tag, how can I retrieve the attribute of those tags?

 

 

sample XML are the following

 

<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">

<title>Example Feed</title>
<subtitle>A subtitle.</subtitle>

try

 

<?php
$xml = simplexml_load_file('myfeed.xml');

echo "<h3>{$xml->title}</h3><h4>{$xml->author->name}<br/>{$xml->author->email}</h4>\n";

foreach ($xml->entry as $entry)
{
    echo "<table border='1' width='500'>\n";
    echo "<tr><th>Title</th><td>{$entry->title}</td></tr>\n";
    echo "<tr>
            <th>Content</th>
            <td>{$entry->content}";
            if ($entry->content)
            foreach ($entry->content->div as $div)
            {   echo "<div>";
                foreach ($div->p as $p)
                    echo "<p>$p</p>";
                echo "</div>";
            } 
    echo   "</td>
        </tr>\n";
    echo "<tr><th>Summary</th><td>{$entry->summary}</td></tr>\n";
    echo "<tr><th>Link</th><td>{$entry->link['href']}</td></tr>\n";
    echo "</table><br /><br />\n" ;
}

?>

 

Content probably should be CDATA
