Question

我在xml文件中从服务器中提取了bios设置，并希望使用php只显示该xml文件的2个字段。

这是我的xml文件（名为ndphlsv02.xml）

<?xml version="1.0" encoding="UTF-8"?>
<SystemConfiguration Model="PowerEdge R720" ServiceTag="xxxxxx" TimeStamp="Wed Aug 12 08:23:51 2015">
    <Component FQDD="LifecycleController.Embedded.1">
        <Attribute Name="LCAttributes.1#CollectSystemInventoryOnRestart">Enabled</Attribute>
        <Attribute Name="LCAttributes.1#PartConfigurationUpdate">Apply always</Attribute>
        <Attribute Name="LCAttributes.1#PartFirmwareUpdate">Match firmware of replaced part</Attribute>
    </Component>
    <Component FQDD="System.Embedded.1">
        <Attribute Name="LCD.1#Configuration">Service Tag</Attribute>
        <Attribute Name="ThermalConfig.1#CriticalEventGenerationInterval">30</Attribute>
        <Attribute Name="ThermalConfig.1#EventGenerationInterval">30</Attribute>
    </Component>
    <Component FQDD="iDRAC.Embedded.1">
        <Attribute Name="IPMILan.1#Enable">Enabled</Attribute>
        <Attribute Name="IPMILan.1#PrivLimit">Administrator</Attribute>
    </Component>
    <Component FQDD="RAID.Integrated.1-1">
        <Attribute Name="RAIDresetConfig">False</Attribute>
        <Attribute Name="RAIDforeignConfig">Ignore</Attribute>
        <Attribute Name="RAIDrekey">False</Attribute>
    </Component>
    <Component FQDD="RAID.Slot.4-1">
        <Attribute Name="RAIDresetConfig">False</Attribute>
        <Attribute Name="RAIDforeignConfig">Ignore</Attribute>
    </Component>
    <Component FQDD="BIOS.Setup.1-1">
        <Attribute Name="MemTest">Disabled</Attribute>
        <Attribute Name="MemOpMode">OptimizerMode</Attribute>
        <Attribute Name="NodeInterleave">Disabled</Attribute>
        <Attribute Name="AcPwrRcvry">Last</Attribute>
        <Attribute Name="AcPwrRcvryDelay">Immediate</Attribute>
        <Attribute Name="NumLock">On</Attribute>
        <Attribute Name="ReportKbdErr">Report</Attribute>
    </Component>
</SystemConfiguration>

这是我到目前为止的PHP代码：

$xml = simplexml_load_file('ndphlsv02.xml') or die("Error: Cannot create object");

$power=$xml->Component[5]->Attribute[3];
$power_attr = $xml->Component[5]->Attribute[3]->attributes();
$status=$xml->Component[5]->Attribute[4];
$status_attr = $xml->Component[5]->Attribute[4]->attributes();
echo $power_attr .": ". $power."<br>";
echo $status_attr .": ". $status;

这很好但我会从每个服务器中提取大约100个xml文件，我注意到我需要提取的和我可能在完全不同的地方。所以这不再适用了：

Component[5]->Attribute[3]

我有没有办法搜索所有xml文件并只输出＆＃34;属性＆＃34;其名称为＆＃34; AcPwrRcvry＆＃34;和＆＃34; AcPwrRcvryDelay＆＃34;和他们的价值观？

谢谢。

易。

$xml = simplexml_load_file('ndphlsv02.xml') or die("Error: Cannot create object");
$xpath = $xml->xpath('/SystemConfiguration/Component/Attribute[@Name="AcPwrRcvry" or @Name="AcPwrRcvryDelay"]');
foreach ($xpath as $attribute) {
    echo $attribute->attributes()->Name . ': ' . $attribute . '<BR>';
}

输出：

AcPwrRcvry: Last
AcPwrRcvryDelay: Immediate

有关详细信息，请参阅xpath doc page
