  • Reading XML with Namespace - Can't get Child Node

    Hi Guys

    I'm having a bit of bother with getting at a name space node. In fact, I've now wasted the better part of a day trying to get at it...

    I have an XML file that I'm pulling down and I can access most of the nodes fine, even the name space nodes are ok. My problem is that I can't access a "child" namespace node. I think I'm pretty close and I'm just missing out on the semantics. But then again, I have been massively wrong before

    Here is a bit of the XML:

    <?xml version="1.0" encoding="UTF-8"?>
    <feed xmlns:ls="http://yourcompany.com/ns/1.0" xml:lang="en-US" xmlns:georss="http://www.georss.org/georss" xmlns="http://www.w3.org/2005/Atom">
      <link type="text/html" href="http://yourcompany.com" rel="alternate"/>
      <title>The Title</title>
        <id>The ID</id>
        <title>The Title</title>
        <content type="html">The HTML Content</content>
        <ls:merchant>The Merchant Name</ls:merchant>
          <ls:city>The City</ls:city>
          <ls:state>The State</ls:state>
          <ls:zip>The Zip Code</ls:zip>
          <ls:country>The Country</ls:country>
          <ls:phone>The Phone Number</ls:phone>
          <georss:point>-28.0067947 153.4065773</georss:point>
          <name>Author Name</name>
    and here is a bit of the boiled down parser:

    // load the file on the DOM
    $dom = new DomDocument();
    $itemList 		= array();
    // get the list of Items.
    $itemElemList 	= $dom->getElementsByTagName('entry');
    for($i=0;$i<$itemElemList->length;$i++) {
    	$itemList[$i] = array (
    		'title'       	 => $itemElemList->item($i)->getElementsByTagName('title')->item(0)->nodeValue,
    		'link'           => $itemElemList->item($i)->getElementsByTagName('link')->item(0)->nodeValue,
    		'description' => $itemElemList->item($i)->getElementsByTagName('description')->item(0)->nodeValue,			
    		'city'           => $itemElemList->item($i)->getElementsByTagNameNS('http://yourcompany.com/ns/1.0', 'city')->item(0)->nodeValue
    Basically, I am trying to get the value from the ls:city node but this is my first real stab at namespaces and I don't really know how to get in at the child node of ls:location.

    Any help would be massively appreciated.

    Ahh... False alarm... I was using the wrong namespace e.g. I was using:

    getElementsByTagNameNS('http://www.w3.org/2005/Atom', 'city')
    instead of:

    getElementsByTagNameNS('http://yourcompany.com/ns/1.0', 'city')
    It's always the small things...

      An easer way to get the text node if you can't access to [0] property of the simpleXMLElement is to use the sprintf function.

      As gwhitescarver at yahoo dot com said, in some version of php 5 it is hard to access to text node of an element, but when you print the element, the [0] property is automaticaly returned.

      Like if you echo() the element, the text node is return.

      The sprintf function do the same:

      $a = array();

      foreach ($xml->children() as $child) {
      $a[$child->getName()] = sprintf("%s", $child);
