XML & PHP Questions

Hi,

I need to solve this very quickly but unfortunately I don't have experience in xml and php.

The site I'm working on uses php and the flash menu is connected to an xml file (see below). Those who do not have the flash plugin will see a standard html menu getting data from the same xml file. The flash/xml menu is working and my challenge is to get the html/xml to work.

I've searched the web and I've read about parsing xml and so on but I'm lost.. I would be so grateful if someone could explain to me how to solve this. Or give me some useful links.

Here's the xml code used by the flash menu;

<?xml version="1.0"?>
<menu>
<item txt="HEADLINE" link="myhtml_0.html">
<item txt="SUBNAV" link="myhtml_1.html"/>
<item txt="SUBNAV" link="myhtml_2.html"/>
<item txt="SUBNAV" link="myhtml_3.html"/>
</item>
<item txt=" HEADLINE" link="myhtml.html">
<item txt="SUBNAV" link="myhtml_4.html"/>
<item txt="SUBNAV" link="myhtml_5.html"/>
<item txt="SUBNAV" link="myhtml_6.html"/>

</item>
<item txt=" HEADLINE" link="myhtml_7.html">
<item txt="SUBNAV" link="myhtml_8.html"/>
<item txt="SUBNAV" link="myhtml_9.html"/>
</menu>

this probably isn't the best way of doing it but it's a way that does work if ur really stuck: http://www.wirelessdevnet.com/channels/wap/features/xmlcast_php.html
I've been trying to get XML to work for quite some tiem too and this is the only thing that I have found so far :/

If I got it right my xml document has no names/attibutes to refer to (see below). Obviously the flash menu can handle this anyway, in some way using the levels, but I believe I need to give the headline and the link a name? What is the attribute for that / how to I add a name in the code below? Or is there a way for php to handle it like flash does?

<?xml version="1.0"?>
<menu>
<item txt="HEADLINE 1" link="myhtml_0.html">
<item txt="LINK 1" link="myhtml_1.html"/>
<item txt="LINK 2" link="myhtml_2.html"/>
<item txt="LINK 3" link="myhtml_3.html"/>
</item>
</menu>

XML is really simple you make up any tags you want you just have to close them and they can't start with special characters or numbers so simply do:
<menu>
<item>
<txt>TXT</txt>
<link>LINK</link>
</item>
</menu>

Also, the way that it is formatted is not the best way to write XML, the above is the way that you should write the file unfortunately I believe flash needs it to be written the other way for it to parse correctly :/

This solved it all, using the xml file without modification;

<?php
$depth = array();

function startElement($parser, $name, $attrs) {
___global $depth;

if ($name == "ITEM") {
for ($i = 1; $i < $depth[$parser]; $i++) {
__echo "  ";
}
echo "<a href=\"".$attrs['LINK']."\">".$attrs['TXT']."</a><br>\n";
}
___$depth[$parser]++;
}

function endElement($parser, $name) {
global $depth;
$depth[$parser]--;
}

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");

if (!xml_parse($xml_parser, file_get_contents('menu.xml'))) {
die(sprintf("XML error: %s at line %d",
_xml_error_string(xml_get_error_code($xml_parser)),
______xml_get_current_line_number($xml_parser)));
}
xml_parser_free($xml_parser);
?>

I need some help with modification of the php file above.. How do I give <item txt="HEADLINE 1">
and <item txt="LINK 1"> different font styles/colors? In the file above they are sharing the link (echo "<a href=\"".$attrs['LINK']."\">".$attrs['TXT']."</a><br>\n"😉

I need to separate them but I havn't got u clue how to.. If you know, please explain to me. Or preferably, give me an example of modified code. Thanks!!!
