Question

I have been trying to modify HTML tag elements, I have a huge list of HTML files which needs to be modified.

I need the lines between the images and the following text removed. I am using PHP. I am using a DOMDocument to access all the nodes and I am also able to get the nodepath. But I am unable to get to modify that particular HTML tag from the nodepath. Is this possible?

This is what I have as of now:

$dom = new DOMDocument();
$dom->loadHTMLFile($pathname);
$i=0;
$allNodes = $dom->getElementsByTagName('*');
$tagNamesArray = array();
foreach($allNodes as $node) {
$tagNodePath = $node->getNodePath();
$tagName = end(explode('/',$node->getNodePath()));
$tagNamesArray[$i][1] = $tagName;
$tagNamesArray[$i][2] = $tagNodePath;
$i++;
}

checkForLines($tagNamesArray, $dom);

function checkForLines($tagsArray, $dom) {
$xPath = new DOMXpath($dom);
for($i=0 ; $i<(count($tagsArray)-1) ; $i++) {
    if($tagsArray[$i][1] == 'img' && $tagsArray[$i+1][1] == 'br') {
        echo $tagsArray[$i+1][2].'<br>';
        $lineTag = $xPath->query($tagsArray[$i+1][2]);
        $domElement = $dom->removeChild($lineTag);
    }
}
}

…consider any image and after it some following text(be it <p> or <h1> etc…) between the image and text there are <br> tags which I want removed…

If this is all you want to do:

$dom = new DOMDocument;
$dom->loadHTML( "<img src='foo.png' /><br/><p>Hello World</p>" );

$img = $dom->getElementsByTagName("img");

foreach ( $img as $current ) {
    $sibling = $current->nextSibling;
    if ( $sibling->nodeName === "br" )
        $current->parentNode->removeChild( $sibling );
}

echo $dom->saveHTML();

Which results in the following output:

<img src="foo.png"><p>Hello World</p>
