Question

我正在尝试获取以下最低值的密钥。

答案应该返回：12

keyCount.collect()
res14: Array[(String, Int)] = Array((8,33), (15,347), (5,2257), (2,18117), (16,955), (9,33), (3,1126), (12,18), (1,1009), (11,25), (10,397))

有人知道我会怎么做吗？

谢谢。

您可以使用reduce例如：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <GetListItemsResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/">
            <GetListItemsResult>
                <listitems xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema">
                    <rs:data ItemCount="3">
                       <z:row ows_DocIcon="jpg" ows_LinkFilename="18380014229851.jpg" ows_Modified="2016-10-08 17:27:40" ows_Editor="179440;#asdf" ows_Last_x0020_Modified="2;#2016-10-08 17:29:29" ows_ID="2" ows_Created_x0020_Date="2;#2016-10-08 17:27:40" ows_FileLeafRef="2;#18380014229851.jpg" />
                       <z:row ows_DocIcon="jpg" ows_LinkFilename="18380014229851_2.jpg" ows_Modified="2016-10-08 17:27:40" ows_Editor="179440;#asfd" ows_Last_x0020_Modified="3;#2016-10-08 17:29:29" ows_ID="3" ows_Created_x0020_Date="3;#2016-10-08 17:27:41" ows_FileLeafRef="3;#18380014229851_2.jpg" />
                       <z:row ows_DocIcon="jpg" ows_LinkFilename="18380014229851_3.jpg" ows_Modified="2016-10-08 17:27:40" ows_Editor="179440;#asdf" ows_Last_x0020_Modified="4;#2016-10-08 17:30:03" ows_ID="4" ows_Created_x0020_Date="4;#2016-10-08 17:27:41" ows_FileLeafRef="4;#18380014229851_3.jpg" />
                    </rs:data>
                </listitems>
            </GetListItemsResult>
        </GetListItemsResponse>
    </soap:Body>
</soap:Envelope>

或minBy

$xml = simplexml_load_string($sp->soapClient->__last_response);

foreach($xml->GetListItemsResult as $item)
{
    $ns_li = $item->children('uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882');
    $ns_rs = $ns_li->children('urn:schemas-microsoft-com:rowset');
    $ns_z  = $nr_rs->children('#RowsetSchema');
    echo $ns_z->row;
}

以最低价值获取密钥
