Description of the current situation:
I have a folder full of pages [pages-folder], each page inside that folder has [among other things] a div with id="short-info".
I have a code that pulls all the textContent [which is for this purpose the same as nodeValue]
The code that loads the divs:

$books = $dom->getElementsByTagName['book'];
foreach [$books as $book] {
echo $book->nodeValue, PHP_EOL;
}
?>The above example will output:

Return if there are no matches is an empty DOMNodeList. Check using length property, e.g.:

Note that when using getElementsByTagName that it is a dynamic list. Thus if you have code which adjusts the DOM structure it will change the results of the getElementsByTagName results list.
The following code iterates through a complete set of results and changes them all to a new tag:
Since the list is dynamically updating, $nodes->item[0] is the next "unchanged" tag.

Following Example is of multiple attributes and multiple child nodes. this is being used to make joomla plugin for bulk upload of articles. Gurmukh Singh Bhatti
any html code here
my name is so so

EOT;$dom = new DomDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML[$xml];
$params = $dom->getElementsByTagName['section']; // Find Sections

My first post!
And this is how I get elements by attribute and its value.
For an example, if I want to grab all DIV tags with class name 'className', then...
value1
value2
value3
EOT;$dom = new DomDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML[$xml];
$params = $dom->getElementsByTagName['param'];
foreach [
$params as $param] {
echo $param -> getAttribute['name'].'
';
}
?>
Expected result:
--------------
param1
param2
param3

This is a very simplistic way to traverse xml nodes and childnodes using the DOMDocument class

I don't know if this is that obvious but it was not for me, so in addition to gem at rellim dot com's posting:

I was in need of $dom->getElementsByTagName that would hist magic within a contextNode.
Why i needed getElementsByTagName instead of just simple using an xPath->query is because while looping through the returned nodelist, more nodes with the tagName i was looking for where created.
When using getElementsByTagName, the new nodes are "added" to the nodelist i already am looping through.
When using an xpath query, you wil only loop through the original nodelist, the newly created elements wil not appear in that nodelist.
I was already using an extended class on domDocument, so it was simple to create an kind of getElementsByTagName that would accept an contextNode.
....
So if you bored to search for solutions with DOM like I did, please ensure that your www environment has the correct libxml2 / PHP Version installed on your apache2 server.So the php code to climb along the elements is:
I realised, that there is a different when using different libxml2 versions on Apache2. This code will fail with libxml2 version 2.6.23 and PHP version 5.2.6
--
->It works fine with libxml2 version 2.6.32 and PHP version 5.2.6-3ubuntu4.6
->...and finally it also works with libxml2 2.7.7 and PHP >= 5.3

If you want to move all nodes to another tag you can do it like that
Eg: replace function replaceDomElementTag[DOMDocument $dom, DOMElement $node, string $tagName]
{
$newElement = $dom->createElement[$tagName];
while [$node->childNodes->length]
$newElement->appendChild[$node->childNodes[0]]; $node->parentNode->replaceChild[$newElement, $node];
}$dom = new DOMDocument[];
replaceDomElementTag[$dom, $divElementToReplace, 'p'];
The following takes a list of news items from an XML file [or an RSS feed], assigning it to an array first for a name value pair and then generating an HTML list.

Problem:
You have an XML document that contains filename references to, say, images. Each filename reference is defined by filename.ext tag. You'd like to perform perform additional validation, say, after running the XML document through XSD validation. The additional validation can be any of your choice, in this example, it would be ideal to convert the PHP code to a function. The function would then determine if the images exist and return either an integer value or a boolean.
