PHP and XML: get full node content

Question

I have an XML like:

<elements version="1.0">
    <files>
        <file id="125173909582">
            <text>aaa</text>
            <source>eee</source>
            <tag>InterInChina</tag>
        </file>
    </files>
</elements>

I need to get (as a string) the content of each node, but as it is! For example, frm the xml above, i need to output a string like: aaaeeeInterInChina for each "file" node.

I am now in this situation:

$request_url="http://www.example.com";
$xml=simplexml_load_file($request_url);
foreach($xml->posts->children() as $file) {
    $id=$file["id"];
    $content=$file->asXML();
}

but the $content is not what i need because it's all the node with the also.

Thanks to you all!

Answer 1

you can use something like this;

$data = '<elements version="1.0">
    <files>
        <file id="125173909582">
            <text>aaa</text>
            <source>eee</source>
            <tag>InterInChina</tag>
        </file>
    </files>
</elements>';
//$request_url="http://www.example.com";
//$xml=simplexml_load_file($request_url);
$xml = new SimpleXMLElement($data);//for test

foreach($xml->files as $k=>$data){
    resp = $data->file->text.' '.$data->file->source.' '.$data->file->tag;  
}
var_dump($resp);

You dont want the xml. You want to itterate trough your files. and itterate trough the variables after. You can itterate with foreach:

lets start with setting up your xml like you ahve it with multiple files:

    $content='<elements version="1.0">
    <files>
        <file id="125173909582">
            <text>aaa</text>
            <source>eee</source>
            <tag>InterInChina</tag>
        </file>

        <file id="125173909582">
            <text>bb</text>
            <source>sss</source>
            <tag>bla</tag>
        </file>
    </files>
</elements>';


    $xml = new SimpleXMLElement($content);

now we can itterate it like this:

$xml = new SimpleXMLElement($content);
foreach($xml->files->file as $file){
echo "<h1>file</h1>"; 
    foreach($file as $key=>$value){
        if(!is_array($value)){
            echo $key . " = ".$value."<br>"; 
        }
    }
}

The answer of @mark_smit it's ok... but the right answer of my question is:

$xml = new SimpleXMLElement($content);
foreach($xml->files->file as $file){
    foreach($file as $key=>$value){
        if(!is_array($value)){
            echo "<".$key.">".$value."</".$key.">"; 
        }
    }
}
