How do I access specific nodes in a xml structure via php?

I am trying to parse an xml string $content, which has following structure:

<response>
    <lst name="responseHeader">
        <int name="status">0</int>
        <int name="QTime">269</int></lst>
</response>

I am interested in the two int fields (here with the values 0 and 269).

I load the xml via:

$xml = simplexml_load_string($content);

I then expected that:

$fields = $xml->xpath('int');

would give me an array of those fields, alas, it is empty.

What am I doing wrong? How can I parse the int fields in this example?

try

$xml ='<response>
    <lst name="responseHeader">
        <int name="status">0</int>
        <int name="QTime">269</int></lst>
</response>';


$xml = simplexml_load_string($xml);
print_r($xml);

echo $field = $xml->lst->int[0];
echo $fields = $xml->lst->int[1];

For attributes:-

echo $attr1 = $xml->lst->int[0]->attributes();
echo $attr2 = $xml->lst->int[1]->attributes();

you forget slashes

$fields = $xml->xpath('//int');

also

$status= $xml->xpath('//int[@name="status"]');
$QTime= $xml->xpath('//int[@name="QTime"]');

You need to change your xpath expression little bit like that :

$fields = $xml->xpath('lst/int');

This will return complete array with node value and attribute name value. Then you can fetch them like :

$fields[0]->{0} AND $fields[1]->{0}
