使用SimpleXMLElement遍历XML内部节点

Question

下面是我的XML

<?xml version="1.0" encoding="UTF-8"?>
-<RentListings>
    -<RentListing>
        <Country>UAE</Country>
        <State>Dubai</State>
        <City>Dubai</City>
        <District>Dubailand District</District>
        <Comm>Arabian Ranches</Comm>
        <SubComm>Al Mahra</SubComm>
        <Bedroom>2</Bedroom>
        -<Images>
            <ImageUrl>http://cdn.example.com/img/1.jpg</ImageUrl>
            <ImageUrl>http://cdn.example.com/img/2.jpg</ImageUrl>
            <ImageUrl>http://cdn.example.com/img/3.jpg</ImageUrl>
        </Images>
        <Last_Updated>Jun 1 2014 9:46AM</Last_Updated>
        <Unit_Status>Vacant</Unit_Status>
    </RentListing>
</RentListings>

下面是我从XML中提取细节的代码

$XMLrent = new SimpleXMLElement($xml_here);
foreach($XMLrent->RentListing AS $oEntry){
    echo $oEntry->City;
    **[Images should be place here]**
}

我的问题是我不知道如何检索和遍历<Images>节点

Answer 1

 foreach($oEntry->Images->ImageUrl AS $oImageUrl){
     echo $oImageUrl;
 }
