[2003-11-14 15:29 UTC] konrek at gmx dot net

Description:
------------
<?xml version="1.0" encoding="UTF-8"?>
<page id="1">
<step id="2">
<hello is="3">hallo
</hello>
</step>
</page>

causes infinite recursion

Reproduce code:
---------------
echo "<h2>Test for Tree</h2>";
imppear( 'Tree/Tree' );
// setup a memory tree using nested sets
$tree = Tree::setup( 'Memory_XML', 'test.xml' );

// read the data from the DB and build the tree internally
$data = $tree->setup();
print_r($data);
//print_r($tree->setupByRawData($array ));
echo "<br /> ";
print_r($tree);

Expected result:
----------------
normal Parsing of XML in Tree-Object

Actual result:
--------------
output:

1

you should not use print_r here, but use $tree->varDump() instead, since the structure *is* recursive.
