Question

我试图在xml表中找到一些数据。

如果删除了名称空间，我可以从xml获取数据：

    $nodes = $data->xpath('//Products/Product/productId[.='.$sku.']/parent::*');

但是当我加载真正的xml时，它的格式如下所示，其中包含Products的命名空间和产品的命名空间

的xml：

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?><Products xmlns="http://config.services.bol.com/schemas/product-feed-1.1.xsd">

所以现在使用命名空间我的xpath不再工作了。我尝试注册名称空间并将我的xpath函数更改为此（使用我找到的一些示例代码）：

PHP：

function findit($sku,$xml){
$xml->registerNamespace('prodfeed', 'http://config.services.bol.com/schemas/product-feed-1.1.xsd');
$xml->registerNamespace('prod', 'http://config.services.bol.com/schemas/product-1.1.xsd');

$nodes = $xml->xpath('/prodfeed:Products/prodfeed:Product/prod:productId[.='.$sku.']/parent::*');

var_dump($nodes);

}

但到目前为止它还没有奏效。我在这里朝着正确的方向前进吗？

但是

Answer 1

您正在注册2个名称空间prodfeed和prod，但在您的xpath中，您只使用＆＃39; prodfeed＆＃39;。

如果你能改变这一行，也许会有所帮助：

$nodes = $xml->xpath('/prodfeed:Products/prodfeed:Product/prod:productId[.='.$sku.']/parent::*');

到此：

$nodes = $xml->xpath('/prodfeed:Products/prod:Product/prod:productId[.=' . $sku . ']/parent::*');

Answer 2

XML文档在到达Product元素时会更改默认命名空间，因此此时您需要开始使用prod命名空间而不是prodfeed命名空间。

您还可以通过移动开头来简化查询[＆＃39;回到productId之前，这意味着你不必做父:: *位。

$nodes = $xml->xpath('/prodfeed:Products/prod:Product[prod:productId=' . $sku . ']');

产品和产品命名空间打破了我的xpath
