Hmm I am still having problems with this and realise I did not explain it
all that well so am going to give it another bash.

I want to navigate an xml document and print out the values of the tags and
the tag name where I do not necessarilly know the content of the xml file so
a quick example of the sort of thing I want to do follows:

xml contains the following

<root>
    <tag1>
        Hello
    </tag1>
    <tag2>
        Bye
    </tag2>
</root>

the following displays in a table

Tag1    Tag2
Hello    Bye

Obviuosly this could be a lot more complex but the example is not complete
rubbish for now.

the following is the code I am trying to work with at the moment (all I am
trying to do is get all the data printing at this point no table rubbish):

$domData = $this->Dom->getElementsByTagName("*");
foreach ($domData as $discreetData){
    print $discreetData->nodeName . " = " . $discreetData->nodeValue .
"<br><br>";
}

this will print everything out but will do an extra lot at the beginning for
the root node e.g.

root = Hello Bye
Tag1 = Hello
Tag2 = Bye

I tried the following but then nothing prints out:

if (!$discreetData->hasChildNodes())

Any help would be appreciated.

Thanks,
Eamon.
