Question

Help please on how to extract data like 15,Teaching Periods 1 and 2.,Max 150. e.t.c from the sample html code below using DOMDocument function? I have tried to work around it but having mutiple tags before the text I like to extract makes it harder for me to extract all the content once as I have to save all the extracted data into mysql database.

                   MY SAMPLE CURL CODE

$content3= $dom->getElementsByTagname('p');
$content4 = $dom->getElementsByTagname('b');

        //===========================================
        //=====  EXTRACT P STUFF ====================
        //===========================================

        foreach ($content3 as $value) {
            $contentnew[]= $value;
        print_r($value); 


        echo "Attribute Value = ";
        echo $value->getAttribute('value');
        echo "<br />";


        // let's get hold of the text value from the node
        $mytempvariable=$value->nodeValue;
        print "CONTENT OF P NODE: \n\n$mytempvariable <br /> <br />\n\n\n";
        }
        echo "<br /> <br /> <br />";



        //===========================================
        //===== EXTRACT B STUFF =====================
        //===========================================
        foreach ($content4 as $value) {
            $contentnew[]= $value;


        echo "Attribute Value = ";

        echo "<br />";

        print_r($value); 
        // let's get hold of the text value from the node
        $mytempvariable=$value->nodeValue;

        }
        echo "<br /> <br /> <br />";

I heard I could use ->nextSibling or xpath to extract all the data after all the b nodes but I cant seems to get around using xpath to extract all the relevant data I need.I could I do this please ??

Answer 1

You were very close:

$result = array();
foreach($dom->getElementsByTagName('b') as $node){
    $result[preg_replace('/:\s+$/','',$node->textContent)] = trim($node->nextSibling->textContent);
}
var_dump($result);
