XML to array

[Azala]

This has been covered alot of places, but I can't find anything that will create the kind of array I want for my xml data.

class XMLEngine {

private $Parser;
private $data = array();

public function parse($file){
	$this->Parser = xml_parser_create();
	xml_set_object($this->Parser, &$this);

    xml_parser_set_option($this->Parser, XML_OPTION_SKIP_WHITE, 1);
    xml_parser_set_option($this->Parser, XML_OPTION_CASE_FOLDING, 0);

    xml_set_element_handler($this->Parser, "tagStart", "tagEnd");
    xml_set_character_data_handler($this->Parser, "tagCData");

    xml_parse($this->Parser, $file);
    xml_parser_free($this->Parser);

	return $this->data;
}

private function tagStart($parser, $tag, $attribs){
}

private function tagEnd($parser, $tag){
}

private function tagCData($parser, $cdata){
}
}

XML.file

<?xml version="1.0" encoding="iso-8859-1"?>
<form>
	<table>mySQLTable</table>
	<input>
		<type>text</type>
		<id>email</id>
		<class>normal</class>
		<text>Sometext</text>
		<validation>email</validation>
		<ajax>yes</ajax>
		<length>24</length>
	</input>
</form>

Desired array output

FORM->table->mySQLTable
-------->input->type->text
----------------->id->email
----------------->class->normal
----------------->text->sometext
----------------->validation->email
----------------->ajax->yes
----------------->length->24

Most of the stuff I found on google creates an array for every single tag => value when parsing the XML.

When parsing that XML I want to end up with an array which first contains form, then one that contains table and input and then one array that contains all the tags under input like illustrated above.

Could anyone help me with the start, end and data functions in the above class to create an array like this?

Would be most appreciated.

$str = "<?xml version='1.0' encoding='iso-8859-1'?>
<form>
	<table>mySQLTable</table>
	<input>
		<type>text</type>
		<id>email</id>
		<class>normal</class>
		<text>Sometext</text>
		<validation>email</validation>
		<ajax>yes</ajax>
		<length>24</length>
	</input>
</form> ";

$xml = simplexml_load_string($str);

echo '<pre>', print_r($xml, true), '</pre>';

gives-->

SimpleXMLElement Object
(
    [table] => mySQLTable
    [input] => SimpleXMLElement Object
        (
            [type] => text
            [id] => email
            [class] => normal
            [text] => Sometext
            [validation] => email
            [ajax] => yes
            [length] => 24
        )

)

Then

echo $xml->input->validation; //--> email

The problem with simplexml_load_string is that if the xml looks like this:

<form>
<input>
</input>
<img>
</img>
<input>
</input>
</form>

Then all the "inputs" are grouped together etc etc...I need to make an array that looks exactly like the xml not switching the order of any of the nodes.

Maybe something like this

$str = "<?xml version='1.0' encoding='iso-8859-1'?>
<form>
	<table>mySQLTable</table>
	<input>
		<type>text</type>
		<id>email</id>
		<class>normal</class>
		<text>Sometext</text>
		<validation>email</validation>
		<ajax>yes</ajax>
		<length>24</length>
	</input>
	<image>
		<src>abc.gif</src>
	</image>
	<input>
		<type>text</type>
		<id>name1</id>
		<class>normal</class>
		<text>Barry</text>
		<validation>text</validation>
		<ajax>yes</ajax>
		<length>15</length>
	</input>
</form> ";

$xml = simplexml_load_string($str);
$i=0;
foreach ($xml->children() as $k=>$item) {
	$data[$i++] = array('type'=>$k, 'content'=>$item);
}
echo '<pre>', print_r($data, true), '</pre>';

Thanks!

That's pretty close to what I wanted.

[barand]

here's a slight variation

$xml = simplexml_load_string($str);
$i=0;
$counts = array('table'=>0,'input'=>0,'image'=>0);
foreach ($xml->children() as $k=>$item) {
	$counts[$k]++;
    $data[$k.$counts[$k]] = $item;
}
echo '<pre>', print_r($data, true), '</pre>';

// you can now use
echo $data['input1']->validation;   //--> email
echo $data['input2']->validation;   //--> text
echo $data['image1']->src;          //--> abc.gif
