i'm looking way special type of child out of xml file php. xml:

i want grab name out of there. code: `$sender =

    $sender = $node->getchild('notify');     $sender = $sender->getchild('name');     $sender = $sender->getdata();

but expected isn't working way. in advance help

you can use xpath expression job done. sql query xml.

$results = $xml->xpath("//notify[@type='post']/@name");

assuming xml in $xml, expression reads like

select notify nodes,  type-attribute post, give name-attribute.

$resultswill array, , code example made simplexml. can use same xpath-expression dom though.

here's complete code:

$x = <<<xml <root>     <notify type="post" name="max" />      <notify type="get" name="lisa" />      <notify type="post" name="william" />  </root> xml;  $xml = simplexml_load_string($x); $results = $xml->xpath("//notify[@type='post']/@name"); foreach ($results $result) echo $result . "<br />";

output:

max william
