I have this part of an html page:
<td>
<div class='medals gold'>
</div>
</td>
To extract and print to video the div attribute I used this php code:
$div = $result->getElementByTagName('div');
echo $div->getAttribute('class') . " ";
In this way I get the string medals gold.
Could I extract indeed only the substring gold?
It would be perfect.
You could use preg_split and split the string on the empty space as others suggest
/* it should be `getElementsByTagName`*/
$div=$result->getElementsByTagName('div')->item(0);
list( $junk, $keep )=preg_split('@\s@',$div->getAttribute('class') );
echo $keep;
/* or */
$divs=$result->getElementsByTagName('div');
foreach( $divs as $div ){
list( $junk, $keep )=preg_split('@\s@', $div->getAttribute('class') );
echo $keep;
}
You can use the explode function to split the string medals gold into an array of two strings array('medals', 'gold'):
$div = $result->getElementByTagName('div');
$parts = explode(' ', $div->getAttribute('class'));
echo $parts[1];
split function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0.
Since split function was DEPRECATED in PHP 5.3, and it is also REMOVED in PHP 7.0, so I would suggest you to use explode.
Also
explode() is substantially faster because it doesn't split based on a regular expression, so the string doesn't have to be analyzed by the regex parserpreg_split() is faster and uses PCRE regular expressions for regex splitsSo, it would be better option :
$div = $result->getElementByTagName('div');
$parts = explode(' ', $div->getAttribute('class'));
echo $parts[1];
where you'll get array with 2 strings. //array('medals', 'gold')
