Question

For a given xml,

<?xml version="1.0" encoding="utf-8"?>
<College xmlns:A1="zool:"xmlns:A12="dym:">
    <A1:name>Seattle</A1:name>
    <A1:MiddleName>I</A1:MiddleName>
    <A12:lastname>Roya Asbari</A12:lastname>
</College>

how do i get the name space for each node while iterating.

Also the format of xml would differ everytime, so I am m looking for a generic way.

Answer 1

Setup XML

$xml = <<< XML
<College xmlns:A1="zool:" xmlns:A12="dym:">
    <A1:name>Seattle</A1:name>
    <A1:MiddleName>I</A1:MiddleName>
    <A12:lastname>Roya Asbari</A12:lastname>
</College>
XML;

Getting Element Name, Namespace and Prefix with DOM

$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXml($xml, LIBXML_NOERROR);
foreach($dom->documentElement->childNodes as $child)
{
    printf(
        "Name: %s - NS: %s - Prefix: %s\n",
        $child->nodeName,
        $child->namespaceURI,
        $child->prefix
    );
}

Output (codepad)

Name: A1:name - NS: zool: - Prefix: A1
Name: A1:MiddleName - NS: zool: - Prefix: A1
Name: A12:lastname - NS: dym: - Prefix: A12
