XML with xpath and PHP: How to access the text value of an attribute of an entry

Question

xml:

Answer 1

xpath() returns an array, you have to select the first element of that array, at index 0. Attention: if there's no match, it may return an empty array. Therefore, you should add an if (isset($xpath[0])) clause, just in case.

foreach ($xml->entry as $entry)
{
    $xpath = $entry->xpath('./link[@rel="alternate"]/@href');

    if (isset($xpath[0]))
    {
        echo $xpath[0], "\n";
    }
}

Answer 2

You were close:

./link[@rel='alternate']/@href

Should be the correct XPath to get those values.
