Hi all,

One hour has pass and I can't work out how to get the result of an xpath query!!!

With the below, how can I return one node's value? I mean, how would I say

for each result
echo show_me_the_streetname_value
next

???

Thanks,

Warren


<?php
$xmlDocument = new DOMDocument();
if ($xmlDocument->load('vw_WebsitePropertyData.xml')) {
	$xpath = new DOMXPath($xmlDocument);
	$nodeList = $xpath->query('/dataroot/vw_WebsitePropertyData[RentPerWeek>22]', $xmlDocument);
}
?>

I would do the following:
<?php
$xml = simplexml_load_file("vw_WebsitePropertyData.xml");
 
$results = $xml->xpath("/dataroot/vw_WebsitePropertyData[RentPerWeek>22]'");
 
foreach ($results as $result)
{
   print_r($result);
}
 
?>

Great!

So how would I get a named value from that array object?

Eg.

echo 'Street Name: ' . ?????????????

echo 'Street Name:' . $result[0]

If you have multiple values put it into a for loop like this:
for($i = 0; $i >= count($result) ; $i++)
{
  echo 'Street Name: ' . $result[$i];
}
 
Should work.

Ops made a mistake, sorry.


for($i = 0; $i <= count($result) ; $i++)
{
  echo 'Street Name: ' . $result[$i];
}

I tried that first, and I could see how that would work, but the array contains the SimpleXMLElement object. Below is part of the print_r output

SimpleXMLElement Object ( [ID] => 2 [Contact] => Paul Bradford [Street] => 10 Jeffson Street..............

So I am still lost as to how to pluck the 'street' value from this result set.
