The use of Dom to first remove and then add the width and height to the first img tag from the text.I hope it help you to save your time
<?php
$html = '
<img src="http://www.example.com/images/header.jpg" width="898" height="223" style="border-bottom:5px solid #cccccc;"/>
<img src="http://www.example.com/images/header2.jpg" width="898" height="223" style="border-bottom:5px solid #cccccc;"/>
';
$doc = DOMDocument::loadHTML($html);
$c =0;
foreach($doc->getElementsByTagName('img') as $image){
if ($c>0) continue;
foreach(array('width', 'height') as $attribute_to_remove){
echo $attribute_to_remove;
if($image->hasAttribute($attribute_to_remove)){
$image->removeAttribute($attribute_to_remove);
}
if($attribute_to_remove=='height'){
if(!$image->hasAttribute($attribute_to_remove)){
$image->setAttribute($attribute_to_remove,'220');
}}
if($attribute_to_remove=='width'){
if(!$image->hasAttribute($attribute_to_remove)){
$image->setAttribute($attribute_to_remove,'700');
}}
$c = $c+1;
}
}
echo $doc->saveHTML();

If wanting to set an attribute of an element with unique id of "1"
<?php
$dom = new DomDocument();
$dom->load('test.xml');
$xp = new DomXPath($dom);
$res = $xp->query("//*[@id = '1']");
$res->item(0)->setAttribute('title','2');
$dom->save('test.xml');
?>

@karvjorm,
Using this method is not exactly a good practice. Infact, I think it may be a bug.
Names beginning with "xml" are reserved (for namespaces in this case).
setAttribute() should return false in this case I think, but I suppose it doesn't.
Still, the right way to do it is with createElementNS().
It lets you specify the namespace when creating the element node.
So the equivalent to yours ($html added to allow word wrapping) is:
$dom = new DomDocument('1.0','iso-8859-15');
$html = $dom->createElementNS('http://www.w3.org/1999/xhtml', 'html');
$ht_ml = $dom->appendChild($html);
$ht_ml->setAttribute('xml:lang','fi');
$ht_ml->setAttribute('lang','fi');

$dom = new DomDocument('1.0','iso-8859-15');
$ht_ml = $dom->appendChild($dom->createElement('html'));
$ht_ml->setAttribute('xmlns','http://www.w3.org/1999/xhtml');
$ht_ml->setAttribute('xml:lang','fi');
$ht_ml->setAttribute('lang','fi');
Result:
<?xml version="1.0" encoding="iso-8859-15"?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fi" lang="fi">
