PHP Manipulating HTML from string
I'm reading in an HTML string from a text editor and need to manipulate some of the elements b开发者_C百科efore saving it to the DB.
What I have is something like this:
<h3>Some Text<img src="somelink.jpg" /></h3>
or
<h3><img src="somelink.jpg" />Some Text</h3>
and I need to put it into the following format
<h3>Some Text</h3><div class="img_wrapper"><img src="somelink.jpg" /></div>
This is the solution that I came up with.
$html = '<html><body>' . $field["data"][0] . '</body></html>';
$dom = new DOMDocument();
$dom->loadHTML($html);
$domNodeList = $dom->getElementsByTagName("img");
// Remove Img tags from H3 and place it before the H# tag
foreach ($domNodeList as $domNode) {
if ($domNode->parentNode->nodeName == "h3") {
$parentNode = $domNode->parentNode;
$parentParentNode = $parentNode->parentNode;
$parentParentNode->insertBefore($domNode, $parentNode->nextSibling);
}
}
echo $dom->saveHtml();
You may be looking for a preg_replace
// take a search pattern, wrap the image tag matching parts in a tag
// and put the start and ending parts before the wrapped image tag.
// note: this will not match tags that contain > characters within them,
// and will only handle a single image tag
$output = preg_replace(
'|(<h3>[^<]*)(<img [^>]+>)([^<]*</h3>)|',
'$1$3<div class="img_wrapper">$2</div>',
$input
);
I updated the question with the answer, but for good measure, here it is again in the answers section.
$html = '<html><body>' . $field["data"][0] . '</body></html>';
$dom = new DOMDocument();
$dom->loadHTML($html);
$domNodeList = $dom->getElementsByTagName("img");
// Remove Img tags from H3 and place it before the H# tag
foreach ($domNodeList as $domNode) {
if ($domNode->parentNode->nodeName == "h3") {
$parentNode = $domNode->parentNode;
$parentParentNode = $parentNode->parentNode;
$parentParentNode->insertBefore($domNode, $parentNode->nextSibling);
}
}
echo $dom->saveHtml();
