DOM in PHP

hi there

i've got a problem by inserting a new node into a document.

this is the xml file:

<?xml version="1.0"?>
<satz>
<id>1</id>
<data></data>
<info>some info</info>
</satz>

i want to insert a new tag <info> filled with text from user input.
so i tried with this code:

$doc = new DOMDocument();
$doc->load('daten.xm l');

$neu = $_POST['neu'];

$satz = $doc->getElementsByT agName( "satz" );

$r = $doc->createElemen t( "info", $neu );
$doc->appendChild( $r);

$doc->save('filename .xml');

echo $doc->saveXML();
but this codes adds the <info> tag at the end of the document. how can i insert
the element in the right place?

greets

Did you intend to append the new element to $satz rather than $doc?

If you need more control than that, you probably want the insertBefore
operation rather than append.

(There are many good tutorials on how to use the DOM. Reading one, or at
the very least taking the time to read thru the DOM spec to see what
operations are available, is going to be a lot more effective than
trying to guess.)

I don't know of any specifically with regard to PHP, but there are
certainly lots of articles on using the DOM with Java and other
languages, and the APIs and their behavior *should* be essentially the
same modulo any differences absolutely required by the language.

When I'm looking for training material, I usually start with IBM's
DeveloperWorks website at http://ibm.com/xml -- OK, I admit I'm biased,
but this is still a good starting point for standards education. If you
click on Training on the left side, then select Tutorials, then select
DOM from the drop-down list, you'll see 9 tutorials at various levels of
complexity and specificity. If you go back up to the top and change
"tutorials" to "articles", you'll see another 35 relevant documents;
there are also a few in the "standards" category.

I mostly look at the W3C's website, although I find their pages harder
to digest. Here's a page with all DOM levels:

http://www.w3.org/DOM/DOMTR

And a Google search on "PHP DOM" found this:

http://www.php.net/domxml/

The official specs are written by experts for experts, and unfortunately
companies don't donate editorial expertise, so they can be a bit of an
uphill slog. But they're the authoritative source of info for anything
developed by the W3C, and are definitely worth knowing about and
checking when in doubt.

My usual starting point there is http://www.w3.org/TR


which is a list of all the technical reports they've published,
including all the Recommendations already published and the Working
Drafts still being developed.

yep, but i meant this page: http://www.w3schools.com/

yeah, look there already but it's not explained in detail what each function and
method does.

And note that for PHP 5 and its built-in DOM support you need
<http://www.php.net/manual/en/ref.dom.php>
The domxml extension is for PHP 4.
