dump_mem(); NOT XML STRING??

[dev]

Hey all,

I do this:
$XML=$this->m_obj->dump_mem( true, 'iso-8859-1' );

SO THIS MEANS I HAVE A XML STRING?
if i print it then i get the xml structure!
But printed direclty in a browser i see nothing and only the sourcecode is a
xml but no parsing from clientside,

The real problem is when i do want to combine a xsl and sml file:
$arguments=array("/_xml" => $XML, "/_xsl" => $xslFileData);
$XSLobj=xslt_create();
$result=xslt_process($XSLobj,""arg:/_xml", arg:/_xsl", null, $arguments);

It parse the xsl file but IT NEVER READS FROM THE XML? it doesnt exist?

but when i save the $XML local to a file or i put it in a string it works..?

So why doesnt $this->m_obj->dump_mem( true, 'iso-8859-1' ) delivers a string
valid for this use??

GReetz,
