Simple XML parsing for editing

I have an xml file that is loaded by a Flash animation -- but thats not the point.

I want to load the xml (actually, they are 4 XMLs) display everything in many form fields and when submitting the form updating every xml. Sort of a simple admin backend.

Each xml looks something like this:
[PHP]<?xml version="1.0"?>
<news>
<item title="Title 1" text="Long text 1" url="1.htm" />
<item title="Title 2" text="Long text 2" url="2.htm" />
</news>[/PHP]

Every xml has only two items like that.

I would like to get them in an array like

[b]$xml1[0][title];[/b]
to get "Title 1"

[b]$xml1[1][text];[/b]
to get "Long text 2"

(etc.)

The rest of the system is not a problem, i just need to put all the info inside the xmls in arrays.

Thanks in advance guys!

check the php functions to parse xml

you have to create your own parser, its very easy

i coded a xml parser for a little project and I did it in less than 1 hour

I've trying to use php's manual for this (http://www.php.net/xml)
However, i've been trying to change an example (no.2):

What i have so far is:

PHP:

<?php

class AminoAcid {
    var $title;
    var $text;
    var $url;

    function AminoAcid ($aa) {
        foreach ($aa as $k=>$v)
            $this->$k = $aa[$k];
    }
}

function readDatabase($filename) {
    // read the xml database of aminoacids
    $data = implode("",file($filename));
    $parser = xml_parser_create();
    xml_parser_set_option($parser,XML_OPTION_CASE_FOLDING,0);
    xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,1);
    xml_parse_into_struct($parser,$data,$values,$tags);
    xml_parser_free($parser);

    // loop through the structures
    foreach ($tags as $key=>$val) {
        if ($key == "item") {
            $molranges = $val;
            // each contiguous pair of array entries are the 
            // lower and upper range for each molecule definition
            for ($i=0; $i < count($molranges); $i+=2) {
                    $offset = $molranges[$i] + 1;
                $len = $molranges[$i + 1] - $offset;
                $tdb[] = parseMol(array_slice($values, $offset, $len));
            }
        } else {
            continue;
        }
    }
    return $tdb;
}

function parseMol($mvalues) {
    for ($i=0; $i < count($mvalues); $i++)
        $mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
    return new AminoAcid($mol);
}

$eng1 = readDatabase("../eng/news.xml");
echo "** Database:\n";
print_r($eng1);  //this is just to test if the array gets formed ok, then i will remove it

?>

But... php gives me the following error:

Quote:

Warning: Invalid argument supplied for foreach() in ******.php on line 9

Your filename isnt a password, you dont have to hide it

Your error is on line 44 and the one above

Immediate reason:
return new AminoAcid($mol);

$mol isnt an array

Likely cause:
You screwed up for loop, no }

Likely solution

PHP:

<?php

function parseMol($mvalues) {
    for ($i=0; $i < count($mvalues); $i++)
        $mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
    }
    return new AminoAcid($mol);
}

?>

Since your code was tabbed you should of been able to spot that

Thanks, i'll try that.

The code was basically copied from php.net, i only changed some names from the xml file for mine, i didn't write the actual code.

And i didn't intend to hide the filename, but the path to it

The code you gave me has a parse error. I think this is what you meant:

PHP:

<?php
function parseMol($mvalues) {
    for ($i=0; $i < count($mvalues); $i++) {
        $mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
    }
    return new AminoAcid($mol);
}
?>

But it still gives me the "Warning: Invalid argument supplied for foreach() in /www/sanjuanvip.com/htdocs/loscap/data/news.php on line 9"

Its still because in this line return new AminoAcid($mol); $mol isn't a array. Before you return do a print_r($mol)

$mvalues probably has no values.

Thus, the loop will never execute.

Change that function to this to cater for arrays with no values:

PHP:

<?php

function parseMol($mvalues) {
    $mol = array();
    for ($i=0; $i < count($mvalues); $i++) {
        $mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
    }
    return new AminoAcid($mol);
}
?>

Should clear up the foreach() problem, don't know about any others.
