Example, I have an xml code like this:
$xml=<<<XML
<?xml version="1.0"?>
<cars>
<desc1>
<h1>Title 1</h1>
<p>Content</p>
</desc1>
<desc2>
<h1>Title 1</h1>
<p>Content</p>
</desc2>
</cars>
XML;
How can I grab string between tag <desc1>...</desc1> using simplexml so the output like this:
$output='<h1>Title 1</h1>
<p>Content</p>';
thanks in advance :)
You can use DOMDocument then load that xml into it. Target that desc1 then get its children, save it and put it inside a container string. Example:
$dom = new DOMDocument();
$dom->loadXML($xml);
$output = '';
$desc1 = $dom->getElementsByTagName('desc1')->item(0)->childNodes;
foreach ($desc1 as $children) {
$output .= $dom->saveHTML($children);
}
echo $output;
As an alternative to @Ghost you could use Xpath to fetch the child nodes directly.
$dom = new DOMDocument();
$dom->loadXML($xml);
$xpath = new DOMXpath($dom);
$output = '';
foreach ($xpath->evaluate('//desc1[1]/node()') as $child) {
$output .= $dom->saveHTML($child);
}
echo $output;
The Xpath expression:
Select all desc1 nodes anywhere in the document:
//desc1
Limit to the first found node:
//desc1[1]
Get the child nodes (including text nodes):
//desc1[1]/node()
Just an alternative for your specific simple example:
$output = "";
if(preg_match("/<desc1>[^<]*(<.*>)[^>]*<\/desc1>/s",$xml,$reg)) {
$output = $reg[1];
}
