PHP:DOMDocument - 带有冒号的属性?

2022-01-13 00:00:00 attributes svg php domdocument colon

我正在使用 DOMDocument 来解析 XML (SVG).

I'm using DOMDocument to parse an XML (SVG).

某些节点的属性中带有冒号，例如:

Some nodes have attributes with a colon in it, like :

<svg 
   id="svg2"
   width="1000"
   height="1000"
   sodipodi:version="0.32"
   inkscape:version="0.48.1 "
   ...
>

但是当我这样做时:

$node= DOMDocument->documentElement;
foreach($node->childNodes as $key=>$childnode) {
  foreach($childnode->attributes as $attribute) {
    echo $attribute->name."
";
  }
}

带有 : 的属性在没有第一部分(命名空间)的情况下打印

the attributes with a : are printed without the first part (namespace)

在像这样迭代属性时如何获取该属性的命名空间?

How do I get the namespace for that attribute when iterating through the attributes like this?

推荐答案

答案来自 OP 的评论，nodeName 来自 DOMNode.

Answer from OP's comment, nodeName from DOMNode.

$node= DOMDocument->documentElement;
foreach($node->childNodes as $key=>$childnode) {
  foreach($childnode->attributes as $attribute) {
    echo $attribute->nodeName."
";
  }
}

原答案:

DOMNode 中的 prefix 怎么样?

$node= DOMDocument->documentElement;
foreach($node->childNodes as $key=>$childnode) {
  foreach($childnode->attributes as $attribute) {
    echo $attribute->prefix.":".$attribute->name."
";
  }
}
