Answer 1

You could loop $item->categories->category using a foreach:
$source = <<<DATA
<xml>
<title>Test 123</title>
<categories>
<category>Test1</category>
<category>Test2</category>
</categories>
</xml>
DATA;
$item = simplexml_load_string($source);
foreach ($item->categories->category as $elm) {
echo $elm . PHP_EOL;
}
That will give you:
Test1
Test2

Answer 2

This is what are you searching for?
$xml = new SimpleXMLElement('<item id="1234">
<property name="country_id">
<value>4402</value>
</property>
<property name="rc_maintenance_other">
</property>
<property name="claim_right_shareholder">
</property>
<property name="charges_other">
</property>
<property name="other_expenses_heating">
</property>
<property name="unpaid_bills_amount">
</property>
<property name="iv_person_phone">
<value>03-6756711</value>
</property>
</item>
');
foreach ($xml->xpath('//item[#id="1234"]') as $item)
{
foreach ($item->children() as $child) {
echo $child['name'] ."\n";
}
}
