I'm very interested in using XPath with my projects to handle XML. So I decided
to do some simple testing.

However, I cannot even overcome the simple first step, displaying the whole
tree. I *can* however access the contents of the single nodes of the tree (like
this: ' $txt = $xpath->getData("article/teksti"); ').

No matter what I try there's simply "XPath error in XPath.class.php:5813 The
supplied xPath 'root[1]' does not *uniquely* describe a node in the xml
document.Not unique xpath-query, matched 0-times." The code follows:

I have this simple XML-file that depicts an article:

<?xml version="1.0" encoding="UTF-8" ?>
<article>
	<otsake>Title Here</otsake>
	<teksti>Yabba Pala Plah Blah blaa. Gabber gabba yadda wabba. Shaba dada
baba.</teksti>
	<pvm>19082004</pvm>
	<contact>fa...@ch...</contact>
</article>

And then I tested Xpath 3.5 with this code:

require_once("XPath.class.php");
$xpath = new XPath("vi_articles.xml"); //the xml file above
//Display all the content
$art = $xpath->getData("root[1]");
echo "<hr>koko artikkeli:<br> $art<hr>";
..

In place of 'root[1]' I also tried '/', '/article', 'article', 'article[0]',
'article[1]', '/root', '/root[1]' (and several hundred other variations it seems
8) )

What gives? How to get to the whole tree so I can 'echo' it?

Thanks for reading,
