    echo ' <br>';
}

You don't really need xpath here. You can process this XML using the SimpleXMLElement php class like this:

<pre>
<?php

$xmlStr = '<offers>
<offer><id>1578</id>
    <instock>13</instock>
</offer>
<offer><id>1579</id>
    <property name="EAN">634932593250256</property>
    <property name="Dostępne kolory">Niebiesko-Biały</property>
    <property name="Dostępne rozmiary">L</property>
    <instock>1</instock>
</offer>
</offers>';

$xml = new SimpleXMLElement($xmlStr);

foreach ($xml->offer as $offer)
{
    print_r($offer);
}

Outputs:

SimpleXMLElement Object
(
    [id] => 1578
    [instock] => 13
)
SimpleXMLElement Object
(
    [id] => 1579
    [property] => Array
        (
            [0] => 634932593250256
            [1] => Niebiesko-Biały
            [2] => L
        )

    [instock] => 1
)
