Php Domdocument How To Get That Content Of This Tag?

I am using domDocument hoping to parse this little html code. I am looking for a specific span tag with a specific id. Hello world

Solution 1:

You can use simple getElementById:

$dom->getElementById('CPHCenter_lblOperandName')->nodeValue

or in selector way:

$selector = new DOMXPath($dom);

$list = $selector->query('/html/body//span[@id="CPHCenter_lblOperandName"]');

echo($list->item(0)->nodeValue);

//or foreach($listas$span) { 
    $text = $span->nodeValue;
}

Solution 2:

Your four part question gets an answer in three parts:

1. getElementsByTagName does not take an XPath expression, you need to give it a tag name;
2. Nothing is output because no tag would ever match the tagname you provided (see #1);
3. It looks like what you want is XPath, which means you need to create an XPath object - see the PHP docs for more;

Also, a better method of controlling the libxml errors is to use libxml_use_internal_errors(true) (rather than the '@' operator, which will also hide other, more legitimate errors). That would leave you with code that looks something like this:

<?php    
libxml_use_internal_errors(true);
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
foreach($xpath->query("//span[@id='CPHCenter_lblOperandName']") as$node) {
    echo$node->textContent;
}
