Question

我使用php dom从另一个平台解析xml，从中提取某些数据，然后上传到我自己的平台。但是，当涉及到提取某个节点值时，我才会被卡住，只有当子节点“row”的另一个节点值大于0时。在下面的示例中，我想迭代xml并仅在CPACommission节点值大于0时拉出'affcustomid'值。有没有人有任何想法我怎么能这样做？下面的代码是一个缩短的版本，实际上，我会以与下面相同的格式返回100行。

<row>
<rowid>1</rowid>
<currencysymbol>&#8364;</currencysymbol>
<totalrecords>2145</totalrecords>
<affcustomid>11159_4498302</affcustomid>

<CPACommission>30</CPACommission>
</row>

从XML DOM获取数据的最简单方法是Xpath：

$dom = new DOMDocument();
$dom->load('file.xml');
$xpath = new DOMXpath($dom);

var_dump(
  $xpath->evaluate('string(//row[CPACommission > 0]/affcustomid)')
);

使用SimpleXML会更容易：

$doc = simplexml_load_file('file.xml');
foreach ($doc->row AS $row) { 
    if($row->CPACommission > 0){
        echo $row->affcustomid;
    }
}

但是如果你仍然需要使用DOMDocument：

$doc = new DOMDocument();
$doc->load('file.xml');
foreach ($doc->getElementsByTagName('row') AS $row) { 
    if($row->getElementsByTagName('CPACommission')->item(0)->textContent > 0){
        echo $row->getElementsByTagName('affcustomid')->item(0)->textContent;
    }
}

仅当另一个节点值> 1时，使用PHP DOM提取某个节点值。 0
