PHP XPath查询:
$query = $xpathvar->query('//siri:Service');
foreach($query as $service) {
echo $service->textContent;
// Here I need to also echo this Vehicle's reg
}
目标XML:
<Vehicle>
<CategoryA>
<Service>123123123</Service>
</CategoryA>
<CategoryB>
<SubCategoryA>
<Reg>ASDF_XC1</Reg>
</SubCategoryA>
</CategoryB>
</Vehicle>
// Imagine many more vehicles here each with a service and reg
如何更改PHP以便我也检索每个的Reg?检索时服务和注册必须在同一车辆内(不是随机对)。

如何查询车辆然后将其用作上下文节点来搜索Service
和Reg
?
$vehicles = $xpath->query('//siri:Vehicle');
$pairs = array();
foreach ($vehicles as $vehicle) {
$pairs[] = array(
'Service' => $xpath->evaluate('string(.//siri:Service)', $vehicle),
'Reg' => $xpath->evaluate('string(.//siri:Reg)' , $vehicle),
);
}
