I would avoid converting to/from strings because of all the fun that entities cause when doing so. Leave the DOM objects as a tree and just manipulate the objects to change the tag names, add or remove attributes, etc. But otherwise, yes.

For example, in PHP, you can do something like this:

<?php

require('phpQuery/phpQuery.php'); // JQuery port to PHP

$doc = new DOMDocument();
if (!$doc->loadXML(file_get_contents("/path/to/file.xml")) {
    // handle error
    exit(1);
}

/* Useful function */
function changeElementTagName($elt, $newTagName)
{
    $newelt = $Document->createElement(newTagName);

    // Clone the element's attributes
    foreach($elt->attributes as $attribute) {
        $newelt->setAttribute($attribute->name, $attribute->value);
    }

    // Clone the element's content
    foreach($elt->childNodes as $child) {
        $newelt->appendChild($child->cloneNode(true));
    }

    // Replace the node in the tree
    $elt->parentNode->replaceChild($newelt, $elt);
}


foreach (pq("title") as $titleelt) {
    changeElementTagName($titleelt, "span");
    $titleelt->setAttribute("class", "title");
}

$outputstring = $doc->saveXML();
print $outputstring;

?>

Or whatever. (Note: I have not actually tested this code, and it may not even parse correctly.)
