php - How to set a node of an XML file? -

i've created xml document.

so, now, want find node , set values of node, after research topic, don't know how it.

this document :

<?xml version="1.0" encoding="utf-8"?> <scripts> <script nom="mytools.class.php"> <titre>useful php classes</titre> <date>18/07/2011</date> <options> <option name="topic">tutorials</option> <option name="desc">tutorial you</option> </options> </script> <script nom="index.php"> <titre>blabla</titre> <date>15/07/2011</date> <options> <option name="topic">the homepage</option> </options> </script> </scripts

>

so, build html form theses values, @ moment, can't , set want :(

i want first "script" node :

<script nom="mytools.class.php"> //how set "nom" attribute ? <titre>useful php classes</titre> //how value , set ? <date>18/07/2011</date> <options> <option name="topic">tutorials</option> <option name="desc">tutorial you</option> </options> </script>

i have no problem loop document, not "own choices"

have thought ?

use xpath first dom document

$dom=new domdocument(); $dom->loadxml('file'); // file name of xml file if u have string of xml called $string utilize $dom->loadxml($string) $xpath=new domxpath($dom); $path='//scripts/script[1]'; // first node $elem=$xpath->query($path);

now $elem[0] first script node

if u want elements attribute utilize $path='//scripts/script[@nom='attribute value']'; using path homecoming nodeset script elements having nom attribute of ur given value can see more here

in response bahamut100's comment xpath fot alternative element //options/option

now if u meant getting alternative node attribute value this

$path='//options/option[@attrib_name=attrib_value]'; $elem=$xpath->query($path);

but if u meant getting attributes of node first u have reach node. in ur case u have reach alternative node first

$path='//options/option'; $option=$xpath->query($path);

now $option node list getting first element's attibutes use

$attribute=$option[0]->attributes;

now $attribute namednodemap getting value of first attribute use

$value=$attribute->item(0);
