Bug in importFromString() ????

[J. C. <jan...@im...>]

Hello,

I would like to use the new Version but I got problems when changing
something. Here is a simple example:
======================================================
<?
require_once("XPath.class.php");                       //new
//require_once("XPath.class_V2.php");             //old
$xmlfile="xmlfile.xml";
echo "[new XPath]<BR>";
$xpath = new XPATH($xmlfile);
echo "[appenChild \"TEST\" to \"root[1]\"]<BR>";
$child=$xpath->appendChild("/root[1]","TEST");
echo "[replaceData \"TEST\"]<BR>";
$xpath->replaceData($child,"TEST");
echo "[exportToFile] <BR>";
$xpath->exportToFile($xmlfile,'','<?xml version="1.0" encoding="iso-8859-1"
standalone="yes"'.'?'.'>');
?>
======================================================
This code gives me this output:
======================================================
[new XPath]
[appenChild "TEST" to "root[1]"]
XPath error in XPath.class.php:4524 XPath error in XPath.class.php:1454.
Message: In importFromString(): XML error in given string on line 1 column
0. Reason:syntax error
[replaceData "TEST"]
[exportToFile]
PHP Warning: Undefined variable: PHP_SELF in
C:\Server-Entwicklung-V2\imeso\web\Administration\data\XPath.class.php on
line 4698
======================================================
The XML Code is:
======================================================
<?xml version="1.0" encoding="iso-8859-1" standalone="yes"?><root>
</root>
======================================================
When I use the old version it works nice so I think it might be a bug.
Any help?
(The warning is no problem - I normally comment that section at line 4698)

Cheers
Jan
