- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在尝试提取 <description>
使用 DOMDocument 和 XPath、domXpath 标记来自 XML 文档的数据。我只想要<description>
以标签 <header id="1236">MECHANICAL</header>
开头的数据.到目前为止,我已将其创建为我的 xPath 流程;但是调用数据一直不成功:
($xpath->query('//VehicleDescription/standard[header="MECHANICAL"]/description')
VehicleDescription
.有想法该怎么解决这个吗?请记住,这是一个肥皂结果,所以
VehicleDescription
并且该事项的所有其他数据将随着每个请求而改变。

最佳答案
作为 <VehicleDescription>
node 定义了它自己的默认命名空间(在 xmlns="urn:description7b.services.chrome.com"
中),您需要注册此命名空间并将其用作 XPath 表达式的一部分...
$xpath = new DOMXPath($dom);
$xpath->registerNamespace("def", "urn:description7b.services.chrome.com");
$mecharray = [];
foreach ($xpath->query('//def:VehicleDescription/def:standard[def:header="MECHANICAL"]/def:description') as $mechdescription) {
$mecharray[] = $mechdescription->nodeValue ;
}
def
作为命名空间前缀,但你可以使用任何你想要的,只要它在 XPath 表达式中是相同的。
