I've got this snippet of code that I will be replacing in various places and I was wondering how would I write the pattern to preg_replace it? Thanks!
<div class="leftside item1">
<label for="item1">Item1</label>
</div>
I'd like to replace it with:
<div class="leftside item1">
<label for="item1">Item1</label>
</div>
<div class="rightside item1_select">
<select class="item1_select" id="item1_select">
<option value="">Select one</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
If you want to totally replace it, and the code is constant, use str_replace()
. If the actual string varies somewhat, do NOT use regexes, as they really don't mix well with XML/HTML or SGML, use a parser ( DOMDocument
for instance, with an XPath query and some nodem manipulations).
$html = '<div class="leftside item1">
<label for="item1">Item1</label>
</div>
<p>aa</p>
<div class="leftside item1">
<label for="item1">Item1</label>
</div>';
$d = new DOMDocument();
$d->loadHTML($html);
$add = $d->createDocumentFragment();
$x = new DOMXPath($d);
$list = $x->query("//div[@class='leftside item1']");
if($list->length){
foreach($list as $divnode){
$add->appendXML('<div class="rightside item1_select">
<select class="item1_select" id="item1_select">
<option value="">Select one</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</div>');
if($divnode->nextSibling instanceof DOMNode){
$divnode->parentNode->insertBefore($add,$divnode->nextSibling);
} else {
$divnode->parentNode->appendChild($add);
}
}
}
echo $d->saveHTML();
