I was wondering: how would I change all occurrences of a certain word in a HTML, but only outside of tags?
Example:
Lets say I want to replace all occurrences of myWordToReplace with <a href="#">myWordToReplace</a>
So this html
<p data-something="myWordToReplace"> myWordToReplace andSomeOtherText</p>
should yield
<p data-something="myWordToReplace"> <a href="#">myWordToReplace</a> andSomeOtherText</p>
I was trying to achieve this with regex, but it's also a mess - I thought perhaps a DOM parser would do the trick?
Any help appreciated?
EDIT: @Muhammet's answer will do the trick if all your text is wrapped in some tags - but if parts of your text are without a tag, that text will not be replaced of course. I'm now trying to achieve this too.
Example: if I want to change myWord to someOtherWord:
Nam myWord pharetra <strong>auctor myWord</strong>
Should yield
Nam someOtherWord pharetra <strong>auctor someOtherWord </strong>
but now it only changes the second word - the one inside strong tags.
You could do something like this
$html = file_get_html($file_url);
$content = $html->find('text');
foreach($content as $line) {
if(strpos($line->innertext, 'myWordToReplace') !== false) {
$line->innertext = str_replace('myWordToReplace','<a href="#">myWordToReplace</a>', $line->innertext);
}
}
Here is another DOM-based solution to wrap parts of text nodes into <a> tags (using search as a sample):
$html = "<html><body>\n<!-- This is a comment for search //-->\n<span class=\"search\">New search performed</span></body></html>";
$key = "search";
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$tt = $xpath->query('//text()');
foreach ($xpath->query('//text()') as $textNode) {
$fragment = $dom->createDocumentFragment();
$text = $textNode->nodeValue;
while (($pos = stripos($text, $key)) !== false) {
$fragment->appendChild(new DOMText(substr($text, 0, $pos)));
$word = substr($text, $pos, strlen($key));
$lnk = $dom->createElement('a');
$lnk->appendChild(new DOMText($word));
$lnk->setAttribute('href', '#');
$fragment->appendChild($lnk);
$text = substr($text, $pos + strlen($key));
}
if (!empty($text))
$fragment->appendChild(new DOMText($text));
$textNode->parentNode->replaceChild($fragment, $textNode);
}
echo $dom->saveHTML();
Here is an IDEONE demo
This is working great for me. I don't know why it doesn't take the "data-something", it seems that it doesn't like the dash between the two words. But as it works, I hope it is useful for you.
I am using Simple HTML DOM Library
$my_html = '<p data="myWordToReplace"> myWordToReplace </p>';
$html = str_get_html($my_html);
foreach($html->find('p') as $p) {
if (!empty($p->data) && ($p->data == 'myWordToReplace')) {
$p->innertext = '<a href="#">'. $p->innertext .'</a>';
}
}
echo $html;
