Question

我有以下格式的一些xml数据 -

<xyz:reqResponse 
    xmlns:xyz="http://www.test.com/xyz/" 
    xmlns:akt="http://www.exmple.com/akt/">
  <xyz:version>1.2</xyz:version>
  <xyz:totalRecords>659</xyz:totalRecords>
  <xyz:records>
    <xyz:record>
        <doc>
            <str name="icon_url">http://www.icons.net/icon1.jpg</str>
            <str name="type">Service</str>
            <arr name="bc.recordTitle"><str>Evergreen Club</str></arr>
            <str name="bc.id">KLM0078</str>
            <str name="system.external.id">787678</str>
            <arr name="bc.description">
                <str>Meetings: Church Hall Beaudesert Lane. Open to anyone over 50.</str>
            </arr>
            <str name="code">X1209</str>
            <double name="localval1">-4.00006</double>
            <double name="localval2">-7.00012</double>
            <date name="timestamp">Wed Jun 02 21:19:33 BST 2010</date>
        </doc>
    </xyz:record>
    <xyz:record>
        <doc>
            <str name="icon_url">http://www.icons.net/icon1.jpg</str>
            <str name="type">Service</str>
            <arr name="bc.recordTitle"><str>Evergreen Club</str></arr>
            <str name="bc.id">KLM0078</str>
            <str name="system.external.id">787678</str>
            <arr name="bc.description">
                <str>Meetings: Church Hall Beaudesert Lane. Open to anyone over 50.</str>
            </arr>
            <str name="code">X1209</str>
            <double name="localval1">-4.00006</double>
            <double name="localval2">-7.00012</double>
            <date name="timestamp">Wed Jun 02 21:19:33 BST 2010</date>
        </doc>
    </xyz:record>
  </xyz:records>
</xyz:reqResponse>

我喜欢

$xml = simplexml_load_string($xml_data);            
$namespaces = $xml->getNameSpaces(true);
$data = $xml->children($namespaces['xyz']);

所以，如果我打印

echo $data->totalRecords;  //outputs correctly 659

我正在尝试遍历所有记录并访问各个字段，但不知道如何做到这一点。

我试过像

这样的东西

$records = $data->records;
foreach($records as $record) {
    echo print_r($record, true);
}

但它没有帮助。

我的问题是 - - 如何访问每个<xyz:record>及其子项（<str name="abc">NAbc</str>等？

谢谢，凯

Answer 1

我会使用xpath（）方法：

$xml = simplexml_load_string($xml_data);

$xml->registerXPathNamespace('xyz', 'http://www.test.com/xyz/'); 

$recordArr = $xml->xpath('/xyz:reqResponse/xyz:records/xyz:record');

foreach($recordArr as $record) {
    $strArr = $record->xpath('doc/str');

    foreach($strArr as $str) {
        do what you want with $str
    }
}

（未测试）。

Answer 2

当您选择$data->records时，您选择了所有records个元素，而不是record，我认为您应该使用$data->records->record来识别所有record元素。< / p>

$records = $data->records->record;
foreach($records as $record){
    $doc = $record->doc;
    //Now here you can access all str elements itering through $doc->str elements.
}

这是PHP示例：SimpleXMLElement

更新（正如我们在意大利所说的“你永远不会停止学习”）

只有当xml元素共享相同的命名空间时，才可以将它们作为对象访问，您可以这样做：

$docsCollection = $record->children(); //This will retrieve children within default namespace
$strCollection = $docs->doc->str; //Now we are in the same namespace and can reuse above notation

仅供记录。

如何检索xml数据的子项？
