I done a very nice function to run over the XML element recursivly with SimpleXML, and print it on the screen
here it is:
<?php
$xml_han = new SimpleXMLElement( "data.xml", null, true );
print RecursiveXML( $xml_han );
function RecursiveXML( SimpleXMLElement $han, $preffix = "")
{
if( count( $han->children() ) < 1 )
{
return $preffix . "<" . $han->getName() . warpAttributes( $han->attributes() ) . "> " . $han . " </" . $han->getName() . "><br />";
}
$ret = $preffix . "<" . $han->getName() . warpAttributes( $han->attributes() ) . "><br />";
foreach( $han->children() as $key => $child )
{
$ret .= RecursiveXML($child , $preffix . "|-- " );
}
return $ret;
}
?>
enjoy :)

Quick easy way to turn objectified SimpleXMLElement data into an array.
<?php
function get_xml_from_some_source(){
//blah blah blah build cUrl
$data = @curl_exec($ch);
$newdata = new SimpleXMLElement($data);
$new = xml2array_parse($newdata);
}
function xml2array_parse($xml){
foreach ($xml->children() as $parent => $child){
$return["$parent"] = xml2array_parse($child)?xml2array_parse($child):"$child";
}
return $return;
}
?>
My first post, be nice. ;-)

for XML namespaces such as <dc:creator> in RSS feeds use
<?php
$xml = new SimpleXMLElement($string);
$item = $xml->channel[0]->item[0];
$dc = $item->children("http://purl.org/dc/elements/1.1/");
echo $dc->creator;
?>

I made a slightly differnt approch towards the RecurseXML function. Beeing hungry I had problems with the code, as it did just overwrite two <maincourse>s. So here is what I did:
<?php
$xml = new SimpleXMLElement(
'<meal>
<type>Lunch</type>
<time>12:30</time>
<menu>
<entree>salad</entree>
<maincourse>
<part>ships</part>
<part>steak</part>
</maincourse>
<maincourse>
<part>fisch</part>
<part>rice</part>
</maincourse>
<maincourse>
<part>wine</part>
<part>cheese</part>
</maincourse>
</menu>
</meal>');
$vals = array();
RecurseXML($xml,$vals);
foreach($vals as $key=>$value)
print("{$key} = {$value}<BR>\n");
function RecurseXML($xml,&$vals,$parent="") {
$childs=0;
$child_count=-1; # Not realy needed.
$arr=array();
foreach ($xml->children() as $key=>$value) {
if (in_array($key,$arr)) {
$child_count++;
} else {
$child_count=0;
}
$arr[]=$key;
$k=($parent == "") ? "$key.$child_count" : "$parent.$key.$child_count";
$childs=RecurseXML($value,$vals,$k);
if ($childs==0) {
$vals[$k]= (string)$value;
}
}
return $childs;
}
?>
Output is like this:
type.0 = Lunch
time.0 = 12:30
menu.0.entree.0 = salad
menu.0.maincourse.0.part.0 = ships
menu.0.maincourse.0.part.1 = steak
menu.0.maincourse.0 =
menu.0.maincourse.1.part.0 = fisch
menu.0.maincourse.1.part.1 = rice
menu.0.maincourse.1 =
menu.0.maincourse.2.part.0 = wine
menu.0.maincourse.2.part.1 = cheese
menu.0.maincourse.2 =
menu.0 =
(Not beautiful, but it solved my case...)

Just a warning that the iterable returned from children() contains the '@attributes' key, which is "invisible" during a foreach but can be seen if using a different construct, such as list()=each() or casting to an array before iterating w/ foreach.

Here's a simple, recursive, function to transform XML data into pseudo E4X syntax ie. root.child.value = foobar
<?php
error_reporting(E_ALL);
$xml = new SimpleXMLElement(
'<Patriarch>
<name>Bill</name>
<wife>
<name>Vi</name>
</wife>
<son>
<name>Bill</name>
</son>
<daughter>
<name>Jeri</name>
<husband>
<name>Mark</name>
</husband>
<son>
<name>Greg</name>
</son>
<son>
<name>Tim</name>
</son>
<son>
<name>Mark</name>
</son>
<son>
<name>Josh</name>
<wife>
<name>Kristine</name>
</wife>
<son>
<name>Blake</name>
</son>
<daughter>
<name>Liah</name>
</daughter>
</son>
</daughter>
</Patriarch>');
RecurseXML($xml);
function RecurseXML($xml,$parent="")
{
$child_count = 0;
foreach($xml as $key=>$value)
{
$child_count++;
if(RecurseXML($value,$parent.".".$key) == 0) // no childern, aka "leaf node"
{
print($parent . "." . (string)$key . " = " . (string)$value . "<BR>\n");
}
}
return $child_count;
}
?>
The output....
.name = Bill
.wife.name = Vi
.son.name = Bill
.daughter.name = Jeri
.daughter.husband.name = Mark
.daughter.son.name = Greg
.daughter.son.name = Tim
.daughter.son.name = Mark
.daughter.son.name = Josh
.daughter.son.wife.name = Kristine
.daughter.son.son.name = Blake
.daughter.son.daughter.name = Liah

Sometimes you actually want an array, not a pseudo array. This is especially true when you aren't dealing with attributes (i.e., you just want the array of child nodes).
Do like this:
<?php
$children = $sxml->xpath('child::node()');
?>
The reason you might want this is to be able to use array functions like array_shift, array_pop, etc. This is especially true when you are writing recursive functions. Simplexml works really well in iterative programming, but if you try to implement recursion it gets ugly.

Just a quick addition:
If you need to access a child node which contains a dash, you need to encapsulate it with {""}.
For example:
<?php
foreach ($domain->domain-listing as $product) {
}
?>
The example above doesn't work because of the dash. But instead you need to use:
<?php
foreach ($domain->{"domain-listing"} as $product) {
}
?>
At least for me the second example works perfectly fine.

For anyone who hasn't read Sterling Hughe's article (http://www.zend.com/php5/articles/php5-simplexml.php):
<?php
$xml_document =<<<EOT
<?xml version="1.0"?>
<root xmlns:foo="http://example.com">
<foo:bar>baz</foo:bar>
</root>
EOT;
$xml_document = simplexml_load_xml($xml_document);
$foo_ns_bar = $xml_document->children('http://example.com');
echo $foo_ns_bar->bar[0]; // prints 'baz'
?>

The example below shows the basic use of depth-first recursion to span the xml tree.
This is coded for the command line, and it prints out the original sentance above and then the copy cat sentence it creates itself for comparison, which as you will see; this example is slightly off from, I'll leave it upto you to resolve this issue.
All in all I personaly think xml and recursion go hand in hand, so if you don't understand recursion but know xml and want to use php to manipulate xml you will need to learn about recursion at some point.
<?php
$xml = simplexml_load_string(
'<person>
<child role="son">
<child role="daughter"/>
</child>
<child role="daughter">
<child role="son">
<child role="son"/>
</child>
</child>
</person>');
function recurse($child)
{
foreach($child->children() as $children) {
echo ' who begot a '.$children['role'];
recurse($children);
}
return;
}
foreach($xml->children() as $children) {
echo 'The person begot a '.$children['role'];
recurse($children, 0);
echo '; ';
}
echo "\n";
echo 'The person begot a son who begot a daughter; The person begot a daughter who begot a son; and that son begot a son'."\n";
?>

File:
<category>
<item>text</item>
<bold>text</bold>
<item>text</item>
<item>text</item>
<mark>text</mark>
<bold>text</bold>
</category>
If you want to get also names of the tags, you can use this loop layout:
<?php
foreach($category -> children() as $name => $node){
echo $name.'<br/>';
}
?>
