Yes, simplexml can do this easily. See:
http://www.php.net/simplexml
Example 7. Setting values
Data in SimpleXML doesn't have to be constant. The object allows
for manipulation of all of its elements.
<?php
include 'example.php';
$xml = simplexml_load_string($xmlstr);
$xml->movie[0]->characters->character[0]->name = 'Miss Coder';
echo $xml->asXML();
?>
The above code will output a new XML document, just like the
original, except that the new XML will change Ms. Coder to Miss Coder.
Uros, it looks like you want to change one of the attributes; you
will need to use some of this code to handle the attributes:
Example 4. Using attributes
So far, we have only covered the work of reading element names and
their values. SimpleXML can also access element attributes. Access
attributes of an element just as you would elements of an array.
<?php
include 'example.php';
$xml = simplexml_load_string($xmlstr);
/* Access the <rating> nodes of the first movie.
* Output the rating scale, too. */
foreach ($xml->movie[0]->rating as $rating) {
switch((string) $rating['type']) { // Get attributes as element
indices
case 'thumbs':
echo $rating, ' thumbs up';
break;
case 'stars':
echo $rating, ' stars';
break;
}
}
?>

Hi!
I have XML and I would like to set some values. I almost done the
whole thing but have some problems when looping through some tags
<foo>
<bar id="1" name="bar1" />
<bar id="2" name="bar2" />
...
</foo>
I would like to set value for tag "bar" in some loop and then
export this back to XML. Is this even possible or it's better to
use SimpleXML only for read and create new XML from it.
XML is about 20 rows of data and I'm using PHP 5.0.4 with all XML
included.
