How to find tag name using phpquery?

Question

I am using phpquery to extract some data from a webpage. I need to identify the menu of the page. My implementation is to find each element that has sibilings > 0 and last-child is an "a". My code is:

foreach($this->doc['*'] as $tagObj){
$tag = pq($tagObj);
if(count($tag->siblings()) > 0){
    if($tag->find(":last-child")->tagName  === "a")
        echo trim(strip_tags($tag->html())) . "<br/>";
    }
}

However, I am not getting any output because of

$tag->find(":last-child")->tagName

which isn't returning anything. What would be the reason for this?

Does the pq object have the methods find and sibling? I don't think so.. maybe — Tech Savant

What does the html structure look like at that point? Could it just be that for some reason there aren't any items with siblings and children? — BurningLights

What do you get if you make a var_dump of $tag->find(":last-child") ? Is it the one you searched for? Make a Testcase whisch should return that. Consider to use :last. btw the menu or nav? caus' nav is nav and menu is a <ul>/<ol> with <li> in it with <a> in it. no need to check if the last one is <a> — inetphantom

I don't know this library but perhaps something like this

$siblings = $tag->siblings();
if (($siblingCount = count($siblings)) && $siblings[$siblingCount - 1]->tagName === 'a') {
    echo ...
}

You can do it in reverse check for a:last-child :

For example :

foreach($this->doc['*'] as $tagObj){
$tag = pq($tagObj);
if(count($tag->siblings()) > 0){
    if($tag->find("a:last-child"))
        echo trim(strip_tags($tag->html())) . "<br/>";
    }
}

This will check for the a tag of last-child and you can get its content easily. May this help you.

Maybe you should use :last instead of :last-child

According to the library Google Page:

$li = null;
$doc['ul > li']
        ->addClass('my-new-class')
        ->filter(':last') // <--- :last
                ->addClass('last-li')
// save it anywhere in the chain
                ->toReference($li);

Because phpQueryObject returned by pq implements the Iterator and uses a public array $elements to store all elements, we need to get the element using the get() function, which returns a DOMElement that is has the tagName and nodeName properties:

$q = phpQuery::newDocumentHTML('<div><span class="test-span">Testing test</span></div>');
echo $q->find('.test-span')->get(0)->tagName; // outputs "span"
//echo $q->find('.test-span')->get(0)->nodeName; // outputs "span"

Both properties will output the tag name that has the test-span class which of course is span.
