How to parse nested xml into php?

[semanticnotion]

Hi all i have an xml file e.g

<recipe>
<id>abc</id>
<name>abc</name>
<instructions>
<instruction>
<id>abc</id>
<text>abc</text>
</instruction>
<instruction>
<id>abc2</id>
<text>abc2<text>
<instruction>
<instructions>
<recipe>

on my php file i use

$url = "cafe.xml";
// get xml file contents
$xml = simplexml_load_file($url);

// loop begins
foreach($xml->recipe as $recipe)
{
code;
}

but it only retrieve the recipe id and name so how can i retrieve the instructions.

you need to use Xpath.

but it only retrieve the recipe id and name so how can i retrieve the instructions.

I doubt that statement.

unless you have the same XML errors in your original code, all is retrieved properly. you would be able to get the <instructions > element. depending on what you want exactly, an XPath expression might be faster.

Thanks Dormilich for your reply now i solved the thread read the .xml successfully in php file but now my question is how can i read the client request(web service request) and update the data accordingly in php file.

[Dormilich]

how you read the client request depends on its nature (SOAP, XML-RPC, etc.)

[semanticnotion]

which one is best SOAP or XML-RPC
and would you like to share some useful tutorial about the best one cause i have no idea.

[Dormilich]

I have no idea what is best.
