Question

I’m using Zend_DOM_Query to read HTML elements using DOM.

<input type="text" class="a">
<input type="text" class="a">
<input type="text" class="a">

I load the html and find the <input> and then loop through the results.

foreach($inputss as $input){
}

What I actually want to do is add additional markup after each <input> like another input but of different class name <input type="text" class="b">. At the end my full markup will look like this

<input type="text" class="a">
<input type="text" class="b">
<input type="text" class="a">
<input type="text" class="b">
<input type="text" class="a">
<input type="text" class="b">

I keep seeing examples that use createElement() but nothing that seems to add HTML the way I need it added. Am I missing something?

Answer 1

The easiest way to do this is indeed with createElement:

foreach($inputss as $input){
    $newEl = $input->ownerDocument->createElement('input');
    $newEl->setAttribute('type', 'text');
    $newEl->setAttribute('class', 'b');
    $input->parentElement->insertBefore($newEl, $input->nextSibling);
}

Apart from the last line, which is admittedly a little verbose, this seems quite simple to me.

I suppose you could do this with createDocumentFragment and use appendXML to insert a string of HTML, but I don’t see that that would be significantly easier or quicker.

NB that the reason this works is that within a Zend_Dom_Query_Result object are normal DOM objects, so you can use normal DOM methods on them.
