PHP：DOMDocument - 带有冒号的属性？

Question

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

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 "
   ...
>

But when I do:

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

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

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

Answer 1

You will need to work with namespaces (which is what the colon indicates) explicitly when you use DOMDocument .

Take a look at this method: http://www.php.net/manual/en/domelement.getattributenodens.php

Answer 2

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."\n";
  }
}

Original Answer:

How about prefix from DOMNode ?

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