<articles>
    <article>
    <title></title>
    <text></text>
    <notes>
          <note>
        <code></code>

    </notes>
  </article>

</articles>

i have to do this query (sql speaking :) ): SELECT article WHERE note.code=XXX AND note.text CONTAINS YYY

how can i do that in php?

Answer 1

You use Xpath the query language for xml. W3School have a nice tutorial here: http://www.w3schools.com/XPath/

And to use SimpleXML is simple :P:

$xml = new SimpleXMLElement($xmlstring);
$result = $xml->xpath('/articles/article[code=XXX] and /articles/article[text contains(YYY)]');
foreach ($result as $node)
{
   //Do stuff
}
