基于属性的 xml 数据

Question

如何获取属性名称上以下 xml 的值。

    <list version="1.0">
<meta>
<type>resource-list</type>
</meta>
<resources start="0" count="165">
<resource classname="Quote">
<field name="name">USD/KRW</field>
<field name="price">1131.319946</field>
<field name="symbol">KRW=X</field>
<field name="ts">1371547710</field>
<field name="type">currency</field>
<field name="volume">0</field>
</resource>
<resource classname="Quote">
<field name="name">SILVER 1 OZ 999 NY</field>
<field name="price">0.045962</field>
<field name="symbol">XAG=X</field>
<field name="ts">1371505422</field>
<field name="type">currency</field>
<field name="volume">7</field>
</resource>....

有165个这样的结构

想要获取 银 1 盎司 999 纽约 0.045962 XAG=X 1371505422等

到目前为止我的代码是这样的

$xml = simplexml_load_string($data);

foreach($xml->children() as $resources)
{
    foreach($resources->children() as $resource => $data)
    {
        echo $data->field['name'];
        echo "<br>";
    }


}

Answer 1

根据评论中的XML，应该是：

$xml = simplexml_load_string($data);

foreach($xml->resources->resource as $resource)
{
    foreach($resource->field as $field)
    {
        echo $field->attributes()->name; // e.g. name, price, symbol
        echo (string)$field; // this is the content, e.g. SILVER 1 OZ 999 NY
    }
}

请注意，$xml 始终包含根元素，在本例中为 <list>。

给你。

foreach($xml->children() as $resources)
{
foreach($resources->children() as $resource => $data)
{
    echo $data->field['name'];

    echo "<br>";
    echo $resource->attributes()->name;

}


}

Answer 3

更正的代码：

<quote>
<name>test</name><price>567</price><symbol>xyz</symbol><ts>1371505422</ts>
<type>currency</type>
<volume>7</volume>
</quote>
$xmlObject = new SimpleXMLElement($xmlstring);
foreach ($xmlObject->children() as $node){
echo $node->Company;
echo $node->price;
echo $node->symbol;
echo $node->ts;
echo $node->type;
echo $node->volume;
}

你并没有那么远。按名称查询元素而不是使用children()，您只需要children() 方法用于不在元素命名空间内的子元素。在您的代码中，您刚刚查询了错误的数据，请参见此示例 (Demo)：

$xml = simplexml_load_string($data);

foreach($xml->resources->resource as $resource)
{
    echo "---------------\n";
    foreach($resource->field as $field)
    {
        echo $field['name'], ': ',  // e.g. name, price, symbol
             $field, "\n";          // this is the content, e.g. SILVER 1 OZ 999 NY
    }
}

输出：

---------------
name: USD/KRW
price: 1131.319946
symbol: KRW=X
ts: 1371547710
type: currency
volume: 0
---------------
name: SILVER 1 OZ 999 NY
price: 0.045962
symbol: XAG=X
ts: 1371505422
type: currency
volume: 7

这在基本的 simplexml 使用示例中进行了概述和解释，请参阅：http://php.net/simplexml.examples-basic
