我想在xml文件中搜索特定值，例如 v =“9617.5”，v =“ - 14”，v =“ - 0.145356”。我设法打印获取数组。但是无法从数组中获取值。
答案 0 :(得分：0)
使用Xpath：
$xrf = new SimpleXMLElement($xml);
foreach ($xrf->xpath('//*[@v="9617.5"]') as $x) {
var_dump($x);
}
Xpath是一种表达式语言，用于获取DOM的一部分（SimpleXML是DOM之上的抽象）。它功能非常强大，但如果您将其与SimpleXMLElement::xpath()一起使用，则会受到一些限制。要获得完全支持，您必须使用DOMXpath::evaluate()。

试试这个。
// Loading the XML into a SimpleXmlElement object.
$xml = simplexml_load_string($xml);
echo '<pre>';
$list = recursiveNodeIteration($xml);
print_r($list);
// Reads the node attributes from the given node.
function getAttributesFromNode(SimpleXMLElement $node)
{
$nodeAttributes = [];
foreach ($node->attributes() as $idx => $attribute)
{
$nodeAttributes[$idx] = (string)$attribute;
}
return $nodeAttributes;
}
// A function to recursively run through the node and its children.
function recursiveNodeIteration(SimpleXMLElement $node)
{
// Get the node name for reference.
$nodeName = $node->getName();
// Retrieve the attributes
$attributes = getAttributesFromNode($node);
$children = [];
// Check to see if this node has any children.
if ($node->count() > 0)
{
// If so, run through each child element and retrieve the data.
foreach ($node->children() as $child)
{
$children[] = recursiveNodeIteration($child);
}
}
// Wrap it up in an array and return the dataset.
return [
'name' => $nodeName,
'attributes' => $attributes,
'children' => $children
];
}
这是你的结果：
