A simple program to CRUD node and node values of xml file
How would I get a specific Attribute out of this XML feed?
Example - I have been using a line similar to this to get other XML details but I am unsure how I could change it to get a specific Attribute.
$mainPropertyDetails = $mainPropertyUrl->Attributes->attribute;
Attributes:
<Attributes>
<Attribute>
<Name>bedrooms</Name>
<DisplayName>Bedrooms</DisplayName>
<Value>4 bedrooms</Value>
</Attribute>
<Attribute>
<Name>bathrooms</Name>
<DisplayName>Bathrooms</DisplayName>
<Value>2 bathrooms</Value>
</Attribute>
<Attribute>
<Name>property_type</Name>
<DisplayName>Property type</DisplayName>
<Value>House</Value>
</Attribute>

SimpleXML implements these nodes as an array. If you were to var_dump() this, you would see something like:
// Dump the whole Attributes array
php > var_dump($xml->Attributes);
object(SimpleXMLElement)#6 (1) {
["Attribute"]=>
array(3) {
[0]=>
object(SimpleXMLElement)#2 (3) {
["Name"]=>
string(8) "bedrooms"
["DisplayName"]=>
string(8) "Bedrooms"
["Value"]=>
string(10) "4 bedrooms"
}
[1]=>
object(SimpleXMLElement)#5 (3) {
["Name"]=>
string(9) "bathrooms"
["DisplayName"]=>
string(9) "Bathrooms"
["Value"]=>
string(11) "2 bathrooms"
}
[2]=>
object(SimpleXMLElement)#3 (3) {
["Name"]=>
string(13) "property_type"
["DisplayName"]=>
string(13) "Property type"
["Value"]=>
string(5) "House"
}
}
}
It is therefore just a matter of accessing specific ones by their array index:
// Get the second Attribute node
var_dump($xml->Attributes[0]->Attribute[1]);
object(SimpleXMLElement)#6 (3) {
["Name"]=>
string(9) "bathrooms"
["DisplayName"]=>
string(9) "Bathrooms"
["Value"]=>
string(11) "2 bathrooms"
}
Get the Attribute node based on a child's value:
Using xpath() you can query for the parent Attribute node based on a child's text value:
// Get the Attribute containing the Bathrooms DisplayName
// Child's text value is queried via [AttrName/text()="value"]
var_dump($xml->xpath('//Attributes/Attribute[DisplayName/text()="Bathrooms"]');
array(1) {
[0]=>
object(SimpleXMLElement)#6 (3) {
["Name"]=>
string(9) "bathrooms"
["DisplayName"]=>
string(9) "Bathrooms"
["Value"]=>
string(11) "2 bathrooms"
}
}
