PHP xpath query - xml

[prometheos]

hey,

im having trouble with this dom xpath query....

heres the layout of my xml

<items>
   <item>
        <itemName>
        </itemName>
        <requested>
             <by>
             </by>
             <confirmed>
             </confirmed>
        </requested>
   </item>
   <item>
   </item>
    .
    .
    .
</items>

 

i want it so depending if the item name is a certain thing, to query the 'requested/by' field of that same item? can any1 help me?

heres the code i have

$dom = new DOMDocument();							
	$dom->load($forfilename);
	$xpath = new DOMXPath($dom);
	$a = $xpath->query('item/[itemName='.$itemN.']/../requested/by');

 

any ideas welcome,

thanks in advance:)

Your XML is wrong

 

<item name="whatever">
    <request by="someone" confirmed="true"/>
</item>

 

Then you can use:

 

/item[name="whatever"]

 

Now you have to query all by:

 

/item/request/by | //by

 

And go over each element, retrieve it's value and check if it equals

prometheos, your XPath query is problematic.  One which should retrieve the elements that you are looking for is:

 

/items/item[itemName=...]/requested/by

 

So in PHP, something like:

 

$nodes = $xpath->query('/items/item[itemName="'.$itemN.'"]/requested/by');

 

 

P.S. There is nothing wrong with the structure of the XML, to my eye at least.
